Other sources of documentation

The CatDV Pro 3.0 User Manual is a separate PDF document including screen shots and additional background material, available for free download. If you're not familiar with CatDV you are strongly recommended to read the PDF user manual first. It is also available in printed and bound form for a small handling charge.


Introduction

CatDV 3.0 is a cross-platform media cataloging and video logging tool. The CatDV product family has different members, all sharing the same basic user interface but with different features:

This reference guide describes all three versions. When there are differences, these are indicated in the text.

Cataloging

CatDV will import and catalog media files and video clip data in most popular formats, including:

Media files are indexed with thumbnails and can be played back either as previews or as full screen presentations.

CatDV helps you to keep track of which video clips are where on a tape (and which projects they are used in) by maintaining a catalog of clips, each with timecode in and out values and thumbnail previews. Each clip can be annotated with meta data (such as clip name, description, project, status, date and time of recording, or camera exposure details) that can be used for searching and sorting the catalog.

CatDV lets you organise digital camera images and MP3s as well as digital video. You can present slide shows containing a mix of media formats.

Managing large media files

Full-resolution video files are very large and it is usually impractical to keep them all on-line at the same time. CatDV uses both thumbnail images and low-resolution preview movies to show the contents of clips that are currently off-line. To restore off-line media CatDV generates capture logs for use with the batch capture capability of your editing application.

Logging and scene detection

To simplify logging the contents of a tape and creating a first rough draft of an edited program, CatDV supports automatic scene detection of captured footage. You can review each clip and enter a name and keywords describing the scene, mark it as "good" or not, and enter "in" and "out" points to select portions of interest within the clip.

Video capture

With QuickTime-compatible video capture hardware CatDV will scan a tape and capture previews in a single operation. (If you don't have compatible hardware, however, CatDV will work just as well with media files captured using your existing editing application.)

Editing

Although CatDV is not a fully featured editing application you can create a simple movie by stringing together clips of interest. You can export clips as either self-contained or reference movies, or you can convert a movie using a different codec, for example to create a web movie. You can also consolidate the media files on disk by trimming and deleting unused material.

Tools

Several unique utility functions are provided, such as adjusting the timecode values of a program to match the timecode generated after printing to video to permit recapture from a program tape, exporting "whole tape" batch capture logs, or adding a burnt in security camera-style date and time display.

Workgroup features

Using the optional CatDV Workgroup Server and a relational database you can store clip details in a central shared database accessible via a local area network, thereby allowing different members of a team to work together.


Installation and registration

System requirements

CatDV Pro is available for both Macintosh (Mac OS 8/9 and OS X) and Windows. It requires Java and QuickTime, which you can download for free if they're not already provided on your system:

(Note that you need to do a custom installation and select all components, including "QuickTime for Java".)

Updates

The latest version of CatDV is always available at http://www.catdv.com. You should check this site regularly for updates and bug fixes. Updates are sometimes provided as a base version plus a "patch" consisting of just those files that are new and need to be replaced.

Purchasing CatDV

CatDV Pro works as a 30-day limited-functionality demo until you purchase a license on-line to use the full application. You will then be sent a registration code to unlock the application. Enter the name and registration code in the Registration tab of Preferences.

For sales and registration enquiries please contact sales@squarebox.co.uk; for technical support please contact support@squarebox.co.uk. You can also use the web shortcuts in the CatDV Help menu.

There are separate registration codes for the Personal Edition and Professional Edition of the client application, with different features available in each.


Quick start guide

This section provides a very quick overview of the main features of CatDV. Each feature is described in more detail by following the links (use the back button at the top of this window to return to this page). Please refer to the separate PDF user manual for additional details.

Managing catalogs

CatDV stores clip details and their thumbnails in a catalog:

Catalogs are normally saved in a file with extension .cdv. You can open more than one catalog at the same time and copy and paste clips between them. Catalogs are portable between Macintosh and Windows.

The trial version of CatDV will not let you save catalogs (or export or print data).

With the optional Workgroup Server, CatDV users can store clips in a central shared database rather than in files in the local file system. Even then, however, CatDV still uses the concepts of catalogs as a logical grouping of related clips.

Regardless of whether you are using the single user standalone or the workgroup version of CatDV, to keep catalogs a manageable size you would normally have a separate catalog for each tape, or perhaps each project, rather than storing all your clips in one huge catalog. See managing multiple catalogs for hints on how to manage a large clip library.


Clips

All data within a CatDV catalog is held in the form of clips. There are different types of clip, such as still images, movie files, scenes within a movie, lines of an EDL or batch list, and so on.

Each clip has the following main properties or fields (also referred to as columns when clips are shown in a table). Additional fields that provide full details of the media file format that a clip was imported from are listed separately.

Some of these fields are editable while others are filled in automatically at the time of timport. Depending on the type of the clip, many of these fields will be blank.

Namename of the clip
Notesdescription or other comments you enter about the clip
Binproject bin or directory on disk where the clip came from, used for grouping clips
Tapename of the tape or reel the clip is on
Import sourcethe file that details of this clip were imported from (eg. a movie file, EDL, or batch list)
Source mediathe media file that holds the video data the clip refers to (not necessarily the same as the Import Source)
In & Outtimecode values for the whole clip. The Out point of a clip is the timecode of the frame after the last frame of this clip (and normally equals the In point of the following clip).
Durationthe corresponding clip length, i.e. the difference between In and Out points.
In2 & Out2timecode values for a selection made within the clip
Start & Endcurrent clip bounds, either In/Out or In2/Out2 depending on the Export clips based on selection Preferences option
Postereach clip has a poster thumbnail, normally the first frame of the clip but a different poster can be set in the clip details dialog
Marka general purpose check box to mark clips of interest or to save a selection
Hideclips may be flagged as hidden so they don't normally appear unless the Show hidden menu command is used
Gooda general purpose status field to indicate whether the clip is usable or not
Status codesummarise the results of reviewing a clip (combination of "Good" status with whether a selection has been made)
Exposurea summary of the camera exposure details (available with some DV camcorders)
Record datethe original date/time of recording of the clip or image (available with some DV camcorders and digital cameras)
Dateeither the DV record date, or the first modification time of the source media (which normally corresponds to the time of capture)
User 1 to User 3general purpose user-defined text fields
Transition & Seq. no.available when importing EDLs (edit decision lists)
Onlineindicate whether the clip is online, or a preview or thumbnail is available
Usedhow many sequences a clip appears in (this indicates whether a clip is used in a project or not).
Typeclip type, whether still, audio or movie file, clip within an EDL or batch list, or scene within a movie. For scenes the icon indicates whether a definite scene change at the start or end of the clip has been identified.
FormatA summary of the format of the movie (whether DV, other QuickTime movie, still, etc.). See the list of media-related properties for more details about the media file.

Some of these properties might appear more than once with similar names, for example where long and short forms of the same data are available. Use tool tip text (hover the mouse pointer over a field name) to show a short description of the field if you are unsure which property you are viewing.


Importing clips and movies

You can import clip data into a new or existing CatDV catalog from many different sources. The Open/Import command attempts to determine the file type automatically, though you can also use the Import As submenu to use a specific importer:

Use Import Directory to import all the recognised media files in an entire directory. If the appropriate Preferences option is set it will recursively scan the contents of any subdirectories. Use Scan For New Files to re-scan all the directories previously included in a catalog and import any new files that have been added since last time.


Live Capture

With compatible capture hardware you can scan a tape without capturing it to disk first. (On Macintoshes with internal FireWire interface this capability is built-in. Under Windows a third party VDIG driver may be required to enable the capture capability in QuickTime applications such as CatDV.)

Bring up the capture dialog using the Live Capture menu command or toolbar button. You have the following options:

Enter a tape name, destination file (if relevant) and other options, then press the Start button and start your tape playing to commence a scan or capture. (You need to use the controls on your deck or camcorder because CatDV does not currently provide Firewire device control.)

Use Set Poster while the tape is being scanned to create an additional thumbnail at the current frame and use that as the poster for the scene. (Because the length of a scene is not known in advance during live capture the preference options that let you specify which poster to use have no effect. Instead, the first frame of each scene is used unless you set the poster yourself.)

If necessary, use Power Up to initialise the capture hardware after connecting and powering up your camcorder. Use the Video and Audio buttons to configure the capture source. If no video is recognised when you play a tape try closing the Live Capture window, start the tape playing, and then re-open Live Capture.

If any timecode resets are detected while scanning the tape a new artificial tape name is automatically used for each continuous segment.


Exporting clips and movies

You can export the clip definitions in a CatDV catalog in various formats for use in other applications. Select the clips you want to export and use one of the Export As commands:

Use the Export clips based on selection checkbox in Preferences to select whether the whole clip (as defined by its "in" and "out" timecode values) or a selected portion within each clip (as defined by "in2" and "out2") is exported. (If a clip has no selection the whole clip is always used.)

Note that the trial version of CatDV will not let you export or print clip definitions.


Views

Clips are listed in a main window, which can be displayed in one of two main ways:

When using the main window you can

See also: Customising views, Quick start guide

Sorting clips

Clips have both a 'natural' order within the catalog (usually the order they were imported in) and a display order within each view:


Customising views

Use the Customise views command to create your own view definitions, containing just those columns or properties you are interested in:

Adjusting column widths

You can adjust column widths in a list view by dragging on the column divider line in the header row. If you make changes like this then bring up the Customise views dialog you are asked whether to import the current column widths into the view definition. You can then save the view definition including the column widths. (If you do not save the column widths in this way then they will only apply as long as the current window is open.)

You can also rearrange the order of columns graphically by dragging the column header. However, you need to use the Customise views command to add or remove columns.

User defined fields

Three user defined fields User 1 to User 3 are available for additional keywords or notes. These appear at the top of the clip details dialog, and you can define your own custom labels for these columns, and whether they should be used for grouping or not.

The Professional Edition has an unlimited number of user-defined fields. The first six of these are shown at the top of the clip details dialog, though you can access any of these fields via the details table or in a list view.

When you import clips with QuickTime Meta data, such as ID3 tags in an MP3 file, or Exif tags in a TIFF image, you can set it up so that the value of these tags are automatically copied to specified user defined fields. Simply give a user defined field the same name as a meta data tag (eg. "Flash" or "FNumber", "Artist" or "Track") and that column will be filled in automatically at the time of import.


Clip details dialog

Select Clip Details to bring up a window showing all the properties of a selected clip. This window also shows the thumbnails and media for a clip and is used for logging.

You can bring up the clip details dialog from the main window in several ways: via the menu bar, via a toolbar button, via the context sensitive popup menu, or by double clicking a clip (or control double clicking, depending on how your Preferences are set up).

Viewing media

Logging

  • Review the clip and make a selection of the portion you want to keep by marking "in2" and "out2" points using the buttons in the "movie" tab.
  • Review the selection by playing the selection, or playing the first or last few seconds of the selection.
  • Select a clip status of "good" or "no good" to indicate whether you want to use the clip or not.
  • Enter a name, notes, or user defined fields such as videographer or location, to describe the clip.
  • Select a new poster frame by pressing the Set poster button in the "movie" tab.
  • Select an existing tape or bin name from the combo box, or click in the box and type in a new name.
  • Viewing and editing clip details

    Previews


    Media dialog

    There are several ways to display the media for a selected clip at full size:

    All these options use the media dialog to show the media, either in a window or full screen. Double click or press Escape to close the media dialog. The next topic lists various other keyboard shortcuts you can use to control the media as it's playing.

    There are a number of Preferences options that control how media is played, eg. the slide show delay.


    Media dialog shortcuts

    The following keyboard shortcuts can be used to control the media presentation and mark the clip that is playing:

    Space barplay or pause a movie
    Up, Downmove to previous or next clip in the catalog
    Escapeclose the media dialog and fade out any audio
    Ftoggle into full screen mode. Double click to return to normal mode.
    Tab (or S)start or pause slide show mode
    +, -increase or decrease the audio volume
    [, ]rotate image 90 degrees left or right
    Ddouble the playback size of the movie or image
    Shift-Drestore playback to normal size

    Pplay the selection from start to end (in2 to out2)
    T, Ymove to start/end of a selection (in2/out2)
    S, Eplay start/end of a selection (in2/out2)
    Ctrl-J (or Cmd-I)display clip details dialog

    JKL controls

    The behaviour of the JKL jog-shuttle controls depends on the Preferences setting:

    These keys apply in the media dialog, in the Movie and Preview tab of the clip details dialog, and when playing movies full screen.


    Sequences

    A sequence is a special type of clip that contains a sequence of clips in order. It corresponds to an edited program. A sequence is created:

    Double click a sequence to display it in a special sequence dialog. There, you can:

    The sequence dialog is also used when you use View tape as sequence.

    You can export sequences as an EDL.


    Marking and selecting clips

    You can copy or move clips (together with their thumbnails) between catalogs.

    Use the Mark check box to mark clips of interest or to save the state of a selection:

    You can also mark clips as "good" or not ("no good", or as "maybe" if you are undecided) using the Good field:


    Hidden clips

    Clips may be flagged as being hidden so they don't normally appear in a catalog window. These clips are still part of the catalog, however, and are saved and loaded normally. They can be made visible temporarily by:

    You can hide or unhide selected clips more permanently by using the Hide Selected or Unhide Selected menu commands, or by checking or unchecking the "Hidden" checkbox in the details dialog.

    When you import a DV movie a master clip representing the movie file as a whole is created, as well as separate clips for each scene detected within that movie. In most cases you are likely to be interested in the scenes on a tape, rather than the capture files, so the clips representing the movie file are initially marked as hidden.


    Searching and filtering

    You can search for clips based on one or more clip properties, and also apply a filter so that only those clips matching the filter condition are shown in a window.

    A search or filter can have different types of conditions, all of which must be true for a clip to match:

    When searching you can move forward to the next clip matching the conditions, or search for all clips in one go (all clips that match will be selected). You can also create a new view containing just the matching clips.

    When a filter is in effect only the clips that match the filter are show. Press the filter button to toggle a filter on and off, or select a named filter to apply from the drop down list in the toolbar (Professional Edition only).

    Grouping and Hiding clips are two other ways of excluding clips from being shown in a window, separate from and in addition to the regular filtering mechanism.

    See the page on the enhanced query dialog for details of the query dialog available in the Professional Edition.


    Summary mode

    Sometimes a catalog may contain overlapping or duplicated clip definitions, for example if you import logs from completed projects, or if you capture a tape in several segments.

    If you use a Whole tape capture log to capture tape it's very unlikely that all the file boundaries will fall on an exact scene change boundary. Some scenes will end up spanning more than one imported clip therefore. There are different ways to combine these broken clip segments and join them into a single clip for each scene:

    How summary mode works

    The changes made by summary mode only affect how clips are displayed and exported. The original clips in the catalog are not altered, so you can safely toggle in and out of summary view as required. Summary mode displays a concise description of the scenes on a tape as follows:


    Grouping mode

    Use grouping mode to view all the clips in a catalog by tape, bin, or other picklist property. Select the property to group by from the drop down list at the left of the window, then select the particular item to view.

    More advanced operations are possible:


    Printing

    You can print reports from a catalog consisting of all the clips in the current view:

    To adjust the appearance of printouts:

    Other features


    Source media management

    CatDV deals with both clips and source media. A clip describes a piece of media in abstract terms (tape name, in and out points) whereas a source media file is an actual file on disk that contains a DV stream or other media content, such as stills, audio clips, and so on. A clip may or may not have any source media, but you can only manipulate source media in CatDV if you have a clip that refers to it.

    When you import a media file CatDV analyses that file and creates a clip that refers to and describes the source media. If the file is a movie file then several clips may be created, a master clip for the media file as a whole and one for each scene.

    A source media file need not remain online on disk once it has been imported into a catalog, though obviously you won't be able to play the media file if it no longer exists (or can't be found). The clip details store the last known location of the media file.

    The following commands let you deal with source media in various ways:


    Media file metadata

    CatDV provides detailed information about virtually any kind of media file that you import into a catalog, including stills, audio files, and other formats, not just DV movies.

    All the metadata (ie. information about the file, as opposed to the media content of the file itself) that is stored with the file is extracted at the time of import and displayed in special columns against each clip. (Depending on the file being read, not all the fields will be set).

    This information can be very useful when searching for clips, when grouping similar clips together, or when diagnosing problems with particular files.

    General metadata

    The following fields are potentially applicable to any type of media file:

    VideoA summary of the format of the visual track, including the codec, frame size and frame rate. (If there are several video tracks the overall frame size of the movie is shown.)
    AudioA summary of the format of the audio track, including codec and sample rate.
    ImporterDetails of which QuickTime importer is used to read the file, ie. whether it's a QuickTime .MOV file or another format that needs to be imported into QuickTime.
    FormatA concise summary of the format, based on the Importer, Video and Audio fields. In the case of stills the approximate size of the image in megapixels is shown.
    QT TracksA list of all the tracks in the file, as reported by QuickTime. The 4 character type and subtype codes are shown, eg. "vide/jpeg" is a JPEG video track, while "soun/musi" is a MIDI music track. The size in pixels (Width x Height), the number of samples, and the duration of the track is shown. If a track has a name or is disabled this is indicated also.
    Meta dataAny QuickTime user data, such as movie title or copyright annotations, that might be stored in the file is shown here. This field also shows metadata such as JPEG comments, ID3 tags from MP3 files such as artist and track, and Exif tags (but see also below). Wherever possible the data is decoded to a readable form but sometimes the raw hexadecimal codes are shown.
    TypeThe clip type icon indicates whether a clip is a DV clip, a still, an audio clip, an interactive file (eg. Flash or QuickTime VR), or other movie.
    Aspect RatioThe aspect ratio of the visual frame. In the case of DV the intended display size (4:3 or 16:9) is shown, taking into account the non-square pixel size, even though this won't match the ratio of the frame size.
    Frame rateThe frame rate of the visual track, if known, or an indication if this file is a still.
    Frame sizeThe normal display size of the movie in pixels, after any transformation matrix has been applied. (By contrast, the unscaled size of each track is shown in QT Tracks.)
    Audio RateThe audio sample rate (this is extracted from the Audio column and made available separately so it can be used for grouping).
    Import NotesIf anything unusual about the file is detected, such as audio and video tracks that differ in length or don't seem to relate correctly to the number of media samples, or if there are problems with the timecode, then a warning message may be displayed here.
    DurationThe duration of the media file. The timecode format used depends on the file.
    In (and Out)If the file has a timecode track then the in and out points use this timecode information, otherwise each media file is assumed to start at 0:00:00
    Media pathThe last known location on disk of the source media file.
    Media dateThe modification time of the source media file (typically the time the file was captured or digitized, as opposed to the original record date.)
    Media sizeThe physical size of the source media file in kilobytes or MB. (This is the size of the media file as a whole, not the size for a particular scene.)
    Data rateThe average data rate of the media.

    DV metadata

    The following fields have special meaning for DV clips:

    Aux T/CAdditional user-settable or time of day timecode supported by some cameras. (Professional Edition only)
    DV T/CThe timecode value at the start of each clip as stored in the DV data itself (this may be different from the QuickTime timecode track).
    ExposureCamera exposure details recorded in the DV data at the time of recording by some camera models.
    FormatA summary of the format, such as whether PAL or NTSC, widescreen or normal, and locked or unlocked audio. In the case of DV this field is based on the DV data itself, not on what QuickTime reports. For example, if a captured movie file has been conformed by rendering a new audio track then the Format field might report that the original recording was at 32kHz even though the Audio field reports that the movie has a 48kHz audio track.
    Record DateThe original date and time of recording, stored in the DV data (assuming the clock on the camera was set correctly at the time of recroding).

    Exif metadata

    The following fields have special meaning for JPEG and TIFF files with Exif metadata:

    ExposureA summary of the Exif exposure details (if present). The EV (exposure value) number combines the aperture and exposure times and gives an approximate indication of the overall light intensity in the scene, assuming the shot was exposed correctly and the camera has equivalent sensitivity to ISO100 film. (Typically EV0 would correspond to almost complete darkness, while EV18 might be a pure white object in very bright sunshine.)
    Meta dataThis lists all the Exif tags commonly recorded by a digital camera, such as camera make and model, exposure time, whether flash was used, etc. You can copy these tags out to their own separate columns by defining approriately named user defined columns.
    Record DateIf the Exif data has a DateTimeOriginal or CreationDate tag then this value is extracted and stored in the Rec Date field.

    Import warnings

    When importing movies several consistency checks are applied and warnings may be displayed in the Import notes field under various circumstances. The most common messages and their meanings are shown below. (These warnings are fairly technical in nature and can usually be ignored.)

    Timecode jump
    This indicates that the DV timecode in the captured movie is not strictly continuous, either because the original source tape has a timecode discontinuity, because frames were dropped during capture, or possibly because data corruption occurred or the movie was edited or rendered by computer. If the 'strict' capture option is on each continuous segment is processed separately during import into CatDV.
    Dropped frame(s) between ? and ?
    Repeated frame(s) between ? and ?
    These indicate shorter timecode errors of just a few frames. CatDV treats these differently and does not automatically create a new clip for each continuous segment.
    Timecode differs (DV/QT=?)
    There are two ways to determine the timecode for a particular DV frame, based on the QuickTime 'timecode' track and how far into a movie the frame is, or on the digital data read from the DV stream itself for that frame. Usually these will give the same result but if you have dropped frames on capture or other anomalies occurred the results may be different and CatDV displays a warning during import. If you have set the strict import option then CatDV will always try to use the DV timecode and generate new clips whenever it detects a jump, otherwise it uses QuickTime's concept of the timecode (which may agree more with what other applications use) and displays the DV timecode for reference in the DV T/C field.
    Incorrect length (? short of ?)
    This means the length of the media in the movie does not match the overall length reported by QuickTime for the movie as a whole. This can occur if frames were dropped during capture but other frames are stretched out to maintain the overall movie length. Often the movie is reported as being longer than it really is and the last frame appears as a long frozen still, stretching out to give the movie its overall length. In this case the length that QuickTime thinks the movie is is shown in the message but the clip in CatDV will be shorter and reflect the media that is actually present.
    Audio sample rate mismatch
    If a DV movie has a separate audio track this message indicates that the sample rate of the audio track doesn't agree with that originally recorded in the DV stream. This can happen if the audio was resampled during capture, or if you capture a clip where the audio sample rate changes mid way through, in which case QuickTime can sometimes get confused about the sample rate and create an unplayable audio track.
    Unstable frame at start
    Skipping unstable frame(s) at ?
    When the camcorder starts recording a new scene the tape speed may not have stabilised fully and the DV data in the first frame or two may not have a valid timecode or date/timestamp. Where practical, the unstable data is ignored and the first valid date or timecode is used instead.
    Video and Audio differ by ? seconds (? frames)
    The audio track is shorter than the video track by the amount shown. This may indicate dropped frames or some other capture problem, but it could also mean that the movie was edited or rendered, or that the camcorder doesn't precisely lock audio and video samples. (Don't worry if the quoted difference in seconds and in frames don't agree with each other, this is quite normal as they are calculated differently.)
    ? fps invalid for PAL/NTSC DV
    This indicates that the frame rate is not exactly 25 or 29.97/30 fps respectively, perhaps because the movie was rendered by computer rather than captured with a camera, or because frames were dropped during capture.

    Many of these messages only apply to the clip representing the movie as a whole, which is hidden by default. You should therefore show hidden clips if you are trying to diagnose capture or import problems.

    Controlling how movies are imported

    Use the Strictly base clips on captured DV media preferences option (which is on by default) to:

    Turn off the 'strict' option:


    Preview presets

    When you use the Build Preview Movies command low resolution preview movies are created from your source movies to use even when the original source media is offline.

    The following compression presets are available. The approximate file size for one hour of preview footage at 160x120 resolution is shown in each case. (In the Professional Edition you can create your own customised preview settings using any available QuickTime compressor.)

    Balanced
    Video: Sorenson 3, 8 fps, medium quality. Audio: Qualcomm PureVoice 22kHz. (110 MB/hr)
    Speed
    Video: Motion JPEG, 6 fps, low quality. Audio: IMA 4:1 11kHz. (110 MB/hr)
    Quality
    Video: Sorenson, 12.5 fps, medium quality. Audio: QDesign Music 22KHz. (140 MB/hr)
    Speed + Quality
    Video: Motion JPEG, 8 fps, medium quality. Audio: IMA 4:1 22kHz. (250 MB/hr)
    File Size
    Video: Sorenson, 6 fps, low quality. Audio: QDesign Music 22kHz. (30 MB/hr)
    Speed + File Size
    Video: Motion JPEG, 5 fps, least quality. Audio: IMA 4:1 11kHz. (80 MB/hr)
    Quality + File Size
    Video: Sorenson, 8 fps, medium/low quality. Audio: QDesign Music 22kHz. (75 MB/hr)
    Balanced (fast)
    Video: Motion JPEG, 8 fps, low quality. Audio: QDesign Music 11kHz. (125 MB/hr)

    The difference in time to compress between the speed optimised and normal presets can be a factor of five or more, but with a corresponding difference in the resulting file size and quality.

    Note that you should not access the preview files from the preview directory directly. They are private to CatDV - this is why they have obscure names like "25,123,4210,64x.mov". Instead, use Export As Movie(s) command, where you can choose to export existing previews as either reference or self contained movies without recompressing them.

    Live capture

    When building previews in Live Capture (using the Scan & Build Previews command) time is at a premium, so this always uses a 'fast' Motion JPEG codec, with IMA 4:1 12 kHz audio. The frame rate and JPEG quality setting are controlled by the Live Capture preview settings in Preferences.

    As less time is available to compress each frame the Live Capture preview file sizes may be bigger than when building previews from movies that have been captured to disk. You may choose to use a smaller preview size for Live Capture therefore.


    Managing multiple catalogs

    If you have a large number of clips to catalog you may find it convenient to create several separate catalog files, for example one per tape or per project. When you open a catalog all the clips from that catalog are loaded into memory so performance may degrade if you have excessively large catalogs, especially if you use large thumbnails.

    Use the Browse catalogs command to list all the catalog files in a directory, together with a summary of their contents:

    Use Catalog Details to enter a brief descriptive comment about each catalog. This description is listed in the Browse Catalogs window to help you determine the correct catalog to open.

    Searching catalogs (Professional Edition only)

    With the Professional Edition you can search all the catalogs in a directory looking for particular keywords:

    With the optional CatDV Workgroup Server you can also publish catalogs into a relational database and perform much more sophisticated queries, at the granularity of individual clips rather than entire catalogs.


    New features in CatDV 3.0

    There are now two different editions of the CatDV client application, the Personal Edition and Professional Edition, each with different feature sets. Unless otherwise noted, the changes above are applicable to both editions of the application. Various additional improvements are specific to the Professional Edition only:


    CatDV 2.x Features

    New features in 2.5

    New features in 2.0


    Professional Edition Features

    The Professional Edition has several features over and above the standard Personal Edition:

    Workgroup features
    The Professional Edition has an additional Workgroup menu that contains commands to share catalogs with other users and search for clips across catalogs in a central clip database.
    Enhanced searching and filtering
    The Professional Edition features a powerful, completely new query dialog, used for both searching within a catalog and when performing remote queries against the shared database (with the optional Workgroup Server). Queries can contain any number of terms, be combined with logical OR and AND operations, and include regular expressions. Queries can also be named and saved for future use. There is a new toolbar Filter drop down that can be used to apply a named clip filter to the window. The Professional Edition also features a powerful Search and Replace tool that allows textual replacements to be made across any logging field, including regular expression pattern matching.
    Unlimited user defined fields
    The Professional Edition allows you to create an unlimited number of user-defined fields, compared with the standard number of three. These can be used to record details such as videographer, producer, project, location, and so on. Each field can store up to 64K of text and is fully searchable. The clip details window provides immediate access to user fields 1 to 6, and access via a scrolling list to the other fields.
    Improved importers and exporters
    The Professional Edition supports several additional file formats, including Final Cut Pro, Avid, dpsVelocity and XML.
    Analog scene detection
    The Professional Edition lets you perform automatic scene detection on clips subsequent to them being imported, via a separate Detect Scenes command, and also lets you tune the sensitivity for this operation. This is useful if too many false scene changes are detected, or if scene changes are missed with the default setting.
    Timezone adjustments
    To allow footage from different cameras, perhaps shot at different locations around the world, to be accurately correlated by date the Professional Edition has a Timezone Adjustment command allows the date to be adjusted based on timezone and camera clock differences.
    JKL jog-shuttle keys
    The Professional Edition supports the use of standard JKL keys to play media backwards or forwards at different speeds in both the clip details dialog, in the media dialog and when playing full screen.
    Additional clip fields
    To support these features and more, the Professional Edition supports several additional columns. These include Aux T/C (which displays the user-settable timecode field supported by some DV cameras), GMT Date, Location Date, Location Timezone, Clock Adjustment, Catalog and Catalog Notes.
    Customisable preview settings
    In Preferences you can customise the size of previews and the compression setting used in addition to using one of the presets.

    Workgroup Features (Professional Edition only)

    Requirements

    To use the workgroup features of CatDV you need to purchase and install the separate CatDV Workgroup Server product, which is available for various server platforms and databases. You also need a Professional Edition license for each client that will be using the server.

    Note that because most Internet firewalls block access to non-standard ports you normally need direct access to the server machine from each client machine via a local area network.

    Connecting to the server

    Use the Log On To Server command in the Workgroup menu and enter the hostname or IP address of the machine running the CatDV Server. When you press OK you will be logged on to the server and the other Workgroup menu commands will be enabled, or you may see a message that a connection failure occurred.

    To check that you have established a connection with the server program use the Server Status command to display some statistics about the operation of the server, such as how many catalogs and clips are contained in the remote database.

    Publishing catalogs

    If you have created catalogs and saved them locally on your hard disk you need to publish them to make them available to other users via the shared database. Once they are stored in the shared database you no longer need the local catalog files (though you may choose to keep these files somewhere as a backup or in case you need access to them when the server is unavailable). Once published to the database you should make all your changes there, however, rather than in the local files, as the local files will not be kept in sync with the database.

    You publish a catalog by opening it and then using the Publish Catalog command. This will publish the catalog from the current window (even if you have just created it and it has never been saved to disk - if you don't require a local copy you can then close the window without saving changes).

    You can also publish an entire directory full of catalog files directly from your local hard disk by using the Publish Folder command.

    Opening a remote catalog

    Use the Browse Database command to view a list of all the catalogs in the remote database, including a short summary of the contents of each catalog. You can open a catalog by double clicking its name in the list. From this window you can also delete catalogs, or search for all the catalogs containing a particular keyword (in either the catalog description or the clip details).

    Querying the remote database

    Use Perform Query to enter search criteria to search for matching clips across the entire remote database. A window is displayed containing the query results, combining all the clips that match, even if they are in different catalogs.

    You can save the query results to a new local catalog file, print them out, export them as a batch list, or make changes to the clips returned, perhaps adding new logging annotations and then publishing the changes back to the remote database.

    Managing catalogs

    Although all the clips in the remote database are stored in the same place, for convenience they are still grouped into logical groupings called catalogs. You should normally create separate catalogs for each tape, or perhaps each shoot or each project, rather than trying to store all your clips in one large catalog. This will make it easier to manage your clips. For example, you can use the Delete Catalog command in Browse Database to delete a catalog from the database. You also minimise the risk of creating a catalog that is too large to open reliably if you only have limited memory available.

    Once you have opened a remote catalog you have a local copy of the clips and thumbnails from that catalog in memory on your machine. If another user on your network edits these clips and publishes their changes to the database you can use Refresh Window to update your window with the latest version from the remote database. The time at which the contents of the window were last synchronised with the remote database is shown as part of the window title. If you have had a window open for a long time it's a good idea to refresh the window before starting to make any changes.

    Publishing changes

    When you open a remote catalog or perform a query and are working with the query results you can edit the clips in your window exactly as if you were working on a normal local catalog file. However, rather than saving any changes to disk with Save Catalog, you normally want to update the clips in the remote database instead, for which you use the Publish Changes command.

    You can add logging notes, change clip names, make selections, select new poster thumbnails, delete unwanted clips, split a clip into two or create new secondary clips, and all these changes will be saved when you publish the changes. You can also create brand new clips, eg. by importing a file or using New Log Entry, but only if you have opened a remote catalog, not if you are viewing query results, as in the latter case it is not defined which catalog the new clips belong to.

    Resolving conflicts

    If two users try to make changes to the same catalog or clips at the same time then only the first set of changes that are published will be saved to the remote database. The second person who attempts to publish changes will receive a warning message stating there were conflicting edits (eg. trying to add a comment to a clip which the previous user has just deleted). All the changes which can be saved without conflict are saved, and the main window is refreshed to show the current contents as per the remote database. Any clips which weren't able to be saved are displayed in a new unsaved changes window. The second user then needs to manually re-apply those changes in the main window, deciding whether and how to resolve any conflicts before trying to publish the changes again.

    When to re-publish a catalog

    If you publish a catalog with the same name and creation time as an existing catalog in the remote database (and your local catalog is newer than the one in the database) then you will overwrite that catalog in the database with the newer one. Normally you should always use Publish Changes, as this automatically merges your changes and attempts to resolve any conflicting edits.

    There are two main situations, however, where you may want to overwrite a catalog by using Publish Catalog instead:

    In both cases note that any change history associated with the old catalog will be lost, and if another user has the same catalog open they will be unable to publish their changes.


    Enhanced query dialog (Professional Edition only)

    With the new enhanced query dialog you can build up complex queries and save them for use later. Use the same query dialog when searching for clips in the catalog locally or querying the remote database (with the optional Workgroup Server).

    Named queries

    Remote searches

    When querying the remote database (with optional Workgroup Server only) you have the following options:

    Local searches

    Regular expressions

    In regular expressions many characters have special meaning to match particular groups of characters. For example, '^' and '$' match the start and end of a line respectively, '.' matches any character, '[A-Za-z]' matches any upper case or lower case letter, '\s' or '[:space:]' means any white space character, '\d' or '[0-9]' or '[:digit:]' means any digit, '\S' means any visible (non-space) character, and '\b' matches a word boundary. '*' means the previous character can match any number of times (0 or more), '?' means it's optional (matches 0 or 1 times), and '+' means matches 1 or more times. To prevent one of these characters from having its special meaning precede it with a '\'. For example, 'h[ea]llo' or '(hello|hallo)' will match 'hello' or 'hallo', while '\(.*\)' will search for pairs of parentheses.

    Using the Search and Replace tool you can search for a regular expression and use the results of that expression in the replacement. Any text that matches a sub-expression in the search term inside parentheses '(' and ')' can be inserted into the replacement text using '\1' for the first term and so on. For example, you could search for '^(\S+) (\S+)' and replace it with '\2 \1' to swap the first two words of each line, or search for '.*XXX.*' and replace it with nothing to delete all comments tagged with the text 'XXX'.


    Additional Importers and Exporters (Professional Edition only)

    Batch lists

    The Professional Edition (and Workgroup Edition) features the following additional export file formats. Use Export As and one of the following:

    It supports the following additional importer, use Import As and:

    XML

    The Professional Edition supports two type of XML export:


    I have many tapes, how do I know what's on them?

    This is the first of a series of How-To notes, describing how to perform various common logging tasks.

    CatDV is designed to help you pull together all the information you have about what's on a tape to make it easier to manage your tape library and find scenes again. It will also manage low resolution previews that you can use even when the contents of a tape are not currently captured to disk.

    1. First you need to load the information into CatDV:
    2. To find clips on a tape it's important that the correct tape identifier is entered for all your clips. Use the editing commands within CatDV to correct any mistakes or missing data. (For example, you could used the Search dialog to find all the clips from a particular project, then group by tape and drag the selected clips onto the correct tape name or use the Bulk Edit command.)
    3. Once your clips are in a CatDV catalog there are lots of things you can do to help you find those of interest. For example, you could:
    4. To build previews for a tape that is currently online (i.e. that has been captured to disk), select all the clips for that tape, ensuring they have the correct tape name, then use Build preview movies. Use the Preference options to determine the size and quality of previews.

    How do I automatically log a tape with an external capture application?

    Assume you are about to start editing a tape and want to log the start and end of each scene. The traditional way to do this involves wearing out your tape and camcorder by painstakingly logging each scene by cueing and reviewing the tape itself. Instead, a better approach is to capture the whole tape to disk first and then log the scenes automatically, as follows:

    1. Cue to the end of your tape and note down the last timecode value recorded on it.
    2. Use the Whole tape capture log command within CatDV and enter the tape name and final timecode value to generate a series of equal length clips that cover the whole tape. Some capture applications have a limit of 2GB per file, others even 1GB (about 9 minutes or 4-1/2 minutes respectively), but apart from that the size you enter doesn't matter.
    3. Select, then export these clips as a batch list suitable for your editing application (Final Cut Pro, Premiere, Cinestream, etc.) using the Export as submenu.
    4. Create a new temporary project within your editing application and import the whole tape capture log, then use your batch capture command to capture the entire tape to disk. You don't need to capture any additional trim handles. After you have successfully captured the long clips to disk you can delete the temporary project.
    5. Alternatively, if your editing application has the facility to capture an entire tape unattended, use that instead of the steps above.
    6. Import all the long captured movie clips into CatDV using either the Import as media or Import directory command. This will scan the movies to identify each scene and extract thumbnails for them.
    7. Use the Summary mode command to view the clips as scenes, merging fragments as required, then edit the summary clips to give each scene a meaningful name. If necessary, open up the clip details dialog by double clicking a clip and view the movie to help you pick a name.
    8. Select all the scenes you want to use in your project then do Export as movie(s), saving normally (allowing references).
    9. Create (or open) the editing project you want to use the scenes in then import all the reference movies you have just generated. Start editing!

    How do I automatically log a tape using Live Capture?

    1. Ensure your system has a suitable FireWire interface and drivers that are compatible with QuickTime.
    2. Connect your camcorder/deck and computer using a FireWire cable and power up the camcorder.
    3. Launch CatDV and open the Live Capture window. If you get an error this probably means you don't have a compatible VDIG driver, but try resetting the FireWire bus by removing and reinserting the cable (with the camcorder still on) and press the Power up button.
    4. Press play on your camcorder or deck and you should see a preview of the video in the monitor window. If necessary check and adjust the Video and Audio capture settings. You should not select any compression here (use DV for video, Uncompressed for audio, and select the same sample rate as your tape is recorded at).
    5. Type in a tape name and select Scan & Build Preview.
    6. Rewind the tape to the start and press play on your camcorder/deck. Press the Start button in the Live Capture window.
    7. CatDV will now scan the tape, simultaneously capturing low resolution previews and detecting scene changes.
    8. Each scene will have a thumbnail poster from the start of the scene, but you can press Set Poster while the tape is playing to use the current frame as a poster instead. (It is normal for the monitor window to show the thumbnail for the current scene rather than the playing video.)
    9. If capture doesn't stop automatically when the end of the tape is reached, or if you want to stop early, press the Stop button. Close the Live Capture window and review the clips in the catalog.

    How can I archive the source material for a project?

    Almost without exception, when you dub to a DV camcorder or deck it will write new timecode (beginning from zero or following on from whatever was previously written to a tape) rather than use the timecode of the original source. Although you can make perfect digital copies by hooking two camcorders (or a camcorder and computer) together with a FireWire cable, the copy will have different timecode, which unfortunately reduces its usefulness for making backups to restore a project from.

    Using CatDV's Map Tape Offsets command, however, you can create a capture log that correctly refers to the location of clips on a copy that you might have made of your original master tapes. This can be particularly useful if you are consolidating the contents of more than one source tape.

    For example, assume you have already used the techniques described earlier to help you log the contents of your source tape(s), scene by scene, and have created an editing project that contains all the clips you might possibly want to use:

    1. Use your editing application to quickly review each scene and trim out any material you know you don't need. (At this stage, you are going for a very rough cut and should err on the side of including any material you are not sure about.)
    2. Cut all the clips you are interested in to the program (i.e. to the timeline or sequencer, depending on the terminology used by your editing application). Place them all on a single track, and don't apply any filters or effects yet. You can also include any non-DV or computer-generated material at this stage, though of course it will need to be rendered. Doing so here has the advantage that you will then be able to batch capture it later!
    3. Print this temporary program to tape, using a fresh blank tape. This will be your working master from now on and you can file away the original recording masters in a safe place.
    4. Export an EDL for this temporary program from your editing application. Note down the start time of this EDL, or the time of a particularly obvious scene transition near the start of the program.
    5. Review the program tape (your "working master") and note down the exact timecode that was actually recorded corresponding to the event you picked in your EDL (either the start or an obvious scene change).
    6. Import the EDL you saved into CatDV and select the program clips from that EDL.
    7. Use the Map tape offsets command and enter the original and new timecode values you noted earlier (from the EDL and program tape, respectively). Enter an identifier to identify your working master tape. This will update all the program clips to refer to the actual location of the clips on your new master tape.
    8. Use the Export as submenu to export the modified program clips as a batch log and import the log into a new project in your editing application.
    9. Batch capture the clips for the new project from your new working master tape and edit away!

    This technique works particularly well if you are combining material from several tapes but the clips for all your rough cuts fit on a single working master tape, as it means all the material needed for that project is archived in one convenient place - and you have a backup of your precious recording masters! You can still use this technique if your working cuts span more than one tape but you would then need to split your temporary program by hand when you print to video.


    How can I merge two EditDV/Cinestream projects together?

    You can't directly merge together two EditDV/Cinestream projects but you can import the clip definitions from one project into another using the EditDV Import capture log command.

    1. First you need to decide which is your main project and which you want to import the clips from. You then need to decide whether your want to import the definitions of clips from the "project" window or from the "sequencer", i.e. whether you want to preserve the original start and end points of your source clips, or the selected in and out points of those clips as used in your program.
    2. If you want to use your "project" clip definitions, create a temporary CatDV catalog and import the EditDV project. Select all the source clips from the catalog and export them as an EditDV capture log.
    3. Alternatively, if you want to use your "sequencer" clip definitions, export an EDL from EditDV containing those clip definitions and import the EDL into a temporary CatDV catalog. As before, select the source clips from the catalog and export them as a capture log.
    4. Import the capture log you have generated into your main EditDV project and batch capture the newly merged in clips. You will need to reapply any filters or transitions to those clips.

    How do I use CatDV with other applications?

    CatDV will import and export clip data to a variety of non-linear video editing systems and other applications.

    Many project and batch file formats are directly supported. For example, CatDV will directly read EditDV/Cinestream project files, and can export an EditDV/Cinestream capture log. It will import and export Final Cut Pro batch lists, and can export clips as a Premiere batch capture log. CatDV can import clips from Premiere if you first export them as a CMX EDL or tab separated text file.

    Most other NLEs can also export and import clip lists in a form that is compatible with CatDV, as both CMX EDLs and tab separated text are fairly universal file formats. If necessary you can use a text editor to adjust the file format.

    Finally, you can import and export clips between CatDV and other applications in any QuickTime-supported media file format, including .MOV and .AVI files.

    Tab separated text

    Use tab separated text to exchange data with a wide variety of other applications, including spreadsheets, databases or other logging applications, or even a "pencil and paper" log that you typed in to a word processor or text editor.

    To export clips:

    When importing tab separated text CatDV uses a smart algorithm that tries to guess the format of the file used and extract as much information as possible.


    How can I edit and present a program within CatDV?

    A very common task if you have recorded and captured a whole tape of material is to produce a condensed version of the edited highlights to show to people.

    If you want to edit together a finished program, perhaps applying special effects, L- or J-cuts, transitions, titles, voiceovers and so on, you would of course use a fully featured non linear editing package. If all you want is a simple "cuts only" selection of the highlights, however, then you can use the capabilities built in to CatDV as a quick and effective alternative:

    1. Capture the material you want to use to disk and import the media files into CatDV. (Alternatively, if disk space is limited and 'preview' quality is sufficient for your needs at this stage, use the Scan & Build Previews command in Live Capture.)
    2. CatDV will automatically detect and produce a clip for each scene. (Either use Summary mode or enable the Auto-merge DV clips belonging to same shot Preference option if a scene might span across more than one movie file.)
    3. Use the Clip details window to review each scene in turn. Play the clip (in the Movie or Preview tab as appropriate) and mark In and Out points around the section you want to keep.
    4. If you don't want to include that scene in your highlights, select "No Good" from the Good drop down list.
    5. If you want to include a scene in its entirety select "Good" from the drop down list. (If you have already made a selection you can leave the Good value blank as making a selection implies that you've reviewed the clip and want to use it.)
    6. If you want to include two separate sections from the same scene you can either duplicate the clip or create a new secondary clip for the current selection from within the Clip Details dialog.
    7. As an alternative to using the Clip Details dialog you can use the Media dialog to review the clips. Use the keyboard shortcuts 'I' and 'O' to mark selection in and out points as a clip is playing, 'G' or 'N' to mark the clip as good or not, and 'P' to play the selection from start to end. Use the up and down arrows to move to the next clip.
    8. Once you have reviewed your clips and decided which material should be included in the highlights program, select all the clips in the catalog with Control-A (or Command-A). Notice that the status line shows how long your "good selection" is.
    9. Use the Present Movie command, choosing the options "Good clips only" (as mentioned previously, by default this also includes those with a selection) and "Selection (in2/out2)", to show your edited program.
    10. You can set up a filter so your view only shows the good clips (for example to display a storyboard view and rearrange the clip order by dragging and dropping clips). Press the Filter button, select Pick List field "Status", and then select the values "G" and "S" (hold down the command or control keys to select multiple items).
    11. At this stage your edited program is defined by the status of each clip and can still be edited. To make it more permanent use the Select Reviewed command to select just the good clips and then do Create Sequence. This will create a new clip called a sequence that holds your program selections. You can then export this sequence as an EDL or play it in the media dialog at any time.

    How can CatDV help me organise my digital photos?

    You can use CatDV to catalog and present digital photos and other image files stored on your computer:


    How should I deal with timecode resets on a tape?

    If at all possible you should try to avoid timecode resets or breaks from the outset. Timecode discontinuities arise when you play or fast forward past the end of a recording and the camcorder either picks up an incorrect timecode value from an old recording "underneath" or encounters blank tape. You should therefore get in the habit of always using your camcorder's End Search facility every time you Play or Cue a tape, unless you know you have finished and will never record any more on it. (Ideally, you should also avoid pre-striping or reusing tapes as this does nothing to avoid the underlying problem but makes timecode breaks much more difficult to detect.)

    There are two possible strategies for dealing with timecode resets once they occur on a tape:

    Actually, there's a third option which is to ignore timecode altogether. This is fine if all you do is play tapes from beginning to end, but will fail if you ever plan to edit, batch capture or catalog your tapes properly, as having a unique tape name and timecode value to identify each frame of video is an essential pre-requisite for any of these operations.

    Copying a tape is the best solution in the long term, and is straightforward if you have two decks connected by a FireWire cable. The copy will be identical to the original except for having new clean timecode. You can also make a copy via the computer using a single deck or camcorder, by first capturing and concatenating the segments in your editing application and then printing these to tape. The end result is the same though the process is more cumbersome.

    Alternatively, you can think of each timecode segment as a separate "virtual" tape and name them accordingly, for example "Tape 12 #1" and "Tape 12 #2". The fact that the timecode starts from zero in each segment does not matter in this case, because the timecode is unique within each virtual tape. During batch capture, if your editing application asks for "Tape 12 #2" you need to fast forward into the second segment of "Tape 12" and capture from there.

    If you use Live Capture to scan a tape and build up a catalog then if CatDV detects a timecode reset it will automatically create a new virtual tape name for each timecode segment.

    Alternatively, if you have captured a tape containing timecode resets to disk and want to import the movies to CatDV then you should proceed as follows:

    1. Select the Strictly base clips on captured DV media Preference option.
    2. Import the movie file(s).
    3. Show hidden clips, to make sure you correct all the clips including any that are hidden.
    4. Ensure that you are not sorting the view based on Tape or In point, otherwise clips from both timecode segments will be intermingled. Instead, either sort on DV Record Date or leave the view unsorted (ie. in the order the clips were imported to the catalog).
    5. Look at the In (and DV T/C) columns and select all those clips that occur after the timecode reset. Use the Bulk Edit command to give these a new virtual tape name to distinguish them from the first timecode segment.

    It is very important that you set a new virtual tape name like this before building preview movies otherwise the previews will refer to the wrong clips.


    How can I simulate batch capture with CatDV?

    Batch capture (the ability to automatically capture a series of clips from tape based on a specified list of in and out timecode values) is one of the main features used to distinguish "entry level" editing systems from their more expensive "fully featured" cousins.

    Arguably the main benefit of batch capture is that it gives you repeatability: the ability to delete capture files to free up disk space at the end of a project but then to be able to re-capture and re-generate the original project and all its files at a later date if you need to.

    You can use CatDV as a "poor man's" batch capture command to achieve repeatability, even if you use it in conjunction with a low cost NLE which only supports manual capture:

    1. Capture your initial footage to disk by manually starting and stopping capture as required
    2. Use CatDV to log and split the footage into separate files for each scene you're interested in.
    3. Import the movie files generated by CatDV into your NLE, instead of those you originally captured, and edit your project.

    Even if your NLE doesn't support timecode, once you have completed your project you can safely delete the movie files written by CatDV. You can repeatably re-generate them at a later stage by manually recapturing footage that spans all the required clips and repeating steps 1 and 2 above. Because it will detect the same scene changes again, CatDV will generate exactly the same files again, even if the capture files don't have exactly the same start and end points as before. As the files will be named the same and cover the same material, you should be able to re-open your original project and resume editing without noticing any change.
