miroVIDEO DC1
README for version 2.06 11-06-96
This text contains important information for the user of the miroVIDEO DC1 system.
If you encounter any problems when working with the DC1, please read the manual and this text.
During installation:
If you have an older version of the miroVIDEO DC1 software installed on your PC,
please remove this old software using Control Panel / Drivers before installing the new driver.
Installing the miroVIDEO DC1 drivers for Windows 95:
To install the miroVIDEO DC1 drivers under Windows 95,proceed as follows:
Double-click the My computer icon.
Open the Control Panel.
Enable Add New Hardware. The Add New Hardware Wizard window appears.
Click Next.
When being requested, if you want the system to check whether there is new hardware, answer No
because the system will not find miroVIDEO DC1.
Now you are back in the Add New Hardware Wizard window. Click Next.
Click sound, video and game controller. Click Next.
Click Have Disk... to specify from which drive you want to install
the miro drivers.
The default is drive A:\. If the disk is located in another drive, change to this drive
and to the directory. Click OK.
Select miroVIDEO DC1, Motion JPEG Capture/CODEC Board and click Next.
Click Next, to accept the resource settings specified by Windows 95.
The miroVIDEO DC1 driver and the INF files are copied to the Windows 95
system directory (C:\WINDOWS\SYSTEM).
To exit the installation, click Next.
Restart the system. Now You can use your miroVIDEO DC1 board.
Change settings:
Windows 95 configures the hardware settings (addresses, interrupts, and DMA channels) automatically.
To change the settings configured by Windows 95, open the Control Panel and double-click the System
icon. Open the Device Manager. Double-click the Audio Video and Game controller icon and select
miroVIDEO DC1 Motion JPEG Capture CODEC Board. Click on Resources.
To change the resource settings (address, interrupt, DMA channel).
Disable user automatic settings.
Under Settings based on: you see the configurations offered by miroVIDEO DC1:
configuration 0 (default):
Disable user automatic settings. Click on Change settings... .
Select the setting you want to change (address, interrupt, DMA channel): all further settings will
be displayed. Change the desired setting and click OK.
If necessary, change further settings.
If you have changed the settings under Change settings..., these cannot be changed, this means that
Windows 95 cannot change them even if another less flexible hardware component needs these settings.
In case of a hardware conflict, change the miroVIDEO DC1 settings.
Changing further settings:
To change further miroVIDEO DC1 settings,open the Control Panel and double-click Multimedia.
Under Advanced you find miroVIDEO DC1. Double-click this entry. Select the device type Video Codec
or Video Capture. Double-click miroVIDEO DC1 and click Settings.The miroVIDEO DC1 Hardware Settings
window appears. Here you can enable/disable the Burstmode and 0-Wait State.
0 Wait State:
This function accelerates the data transfer via the ISA bus and should be activated.
In case of conflicts, especially with old computer models, this function should be deactivated.
Use DMA Burstmode:
Enabling the DMA burst mode, accelerates the data transfer. By default, the DMA burst mode is
switched on. For some computers, the burst mode may not function properly. When capturing or playing
back video, frames may be lost or there may occur patterns in the image. In this case, disable the
DMA burst mode.
Result of the installation:
After the installation the VIDEODC1.DRV, DC1SETD.HLP, DC1SD.HLP, DC1FD.HLP, MIROVXD.386 files, and the
hard disk speed utility (MIROXPERT.EXE) have been copied to the Windows system directory (default:
C:\WINDOWS\SYSTEM). The SYSTEM.INI file have been complemented.
Output to video:
If you have installed a Windows95 game on your system which has installed "Direct Video" too, it could
happen that there is no video output on the TV playing back videos with the Media Player. The "Print
to Video" option is enabled. In this case you should edit your system.ini file e.g. with the sysedit
and delete or remark the following line in the [drivers32] section:
vids.draw=dvideo.dll
If you decide to remark this line, you can do this by setting a semicolon before this line. After this
you save this modified file. With Windows95 you don't have to restart your system, the modifications
will be taken immediately.
If you like to activate "Direct Video" please remove the semicolon in front of this line and save
your system.ini again
Combination with miroMOVIE (pro):
If you use the VIDEO DC1 in combination with a miroMOVIE (pro) board, and you want to use only the
overlay features of the MOVIE, you must either use the MOVIE's other input connector or disconnect
the VIDEO DC1 and MOVIE or activate the DC1's video loopthru by starting Video Capture.
Resolution limits:
When recording video to the harddisk, the maximum resolution is 320x240 with NTSC (384x288 with PAL
or SECAM). When you create a VIDEO DC1-compressed movie using Video Editor or Adobe Premiere, you
should not exceed this limits, because you wouldn't get any higher video output quality. The VIDEO DC1
hardware, however, is able to handle up to 590x442 on compression / decompression and up to 288 lines
at any width when putting out sequences to video.
Handling 'miroVIDEO DC1 Display':
As soon as the VIDEO DC1 driver is active, the Display dialog is visible either as an icon or as open
dialog box. Whenever the VIDEO DC1 hardware is in use, for example to display a movie, the dialog box
cannot be opened. When the box is open, the hardware is temporarily locked and cannot perform any
compression or decompression.
Compression of 8-bit files like 'flics':
When you want to compress 8-bit (256 colors) files for video output with the miroVIDEO DC1 using Micro-
soft's VidEdit, you have to set 'Video / Video Format' to 24 bit after loading the 8 bit file. Otherwise
the VIDEO DC1 MJPEG driver wouldn't appear in the list of compressors.
Working with Adobe Premiere 1.1:
In Premiere, several settings must be correct to allow for trouble-free work with the miroVIDEO DC1 .
- for capturing video using Premiere's Capture application, 'Capture directly to memory' should be
checked and a capture file should be preallocated.
- within Premiere, the Preview Options must be set to Cache Nothing. The preview window size should
match the resolution of the digitized clips, other important settings are described in the VIDEO DC1
manual.
Known bugs with Adobe Premiere 1.1:
- For the setting of the timescale for featuring to 1 minute in Construction View, effects are not
represented and can' t be modified in this feature.
Workaround: Choose another scale than 1 minute if you want to place it (larger or smaller 1 minute).
Working with Adobe Premiere 4.0 LE:
Adobe Premiere 4.0 LE has the capability to work with presets for a project. These presets contain the
settings for the video-codec, the audio samplerate and the videoformat. The miroVIDEO DC1 driverdisk
contains two presets.
How to use the presets:
- Exit Adobe Premiere 4.0 LE
- Copy the two files PRST0000.PST and PRST0001.PST into the PLUGINS subdirectory of Premiere
(e.g. C:\PREMIERE\PLUGINS)
When Premiere 4.0 LE is started the next time the two presets are available.
Capturing:
Using Adobe Premiere 4.0 LE avoid to change the preview rate in the "MOVIE Capture " menue to "off".
This setting causes a "division by zero" and is not a default setting.
Adobe Premiere 4.0 LE and Win95
If you have problems with the DC1 Display by using Adobe Premiere 4.0 LE, you have to delete the file
premiere.ini in the Windows\System-directory first and then reinstall Adobe Premiere 4.0 LE.
Known bugs:
After having started several applications using the VIDEO DC1 - driver under Windows95 the problem may
occur that there is a lack of continous memory for DMA in your system and an error message appears. In
this case please close all active applications and restart Windows95. In order to get enough continous
memory for DMA-transfer you should
- have at least 16 Megabyte RAM in your system
- add a program which uses the VIDEO DC1 driver (e.g. VidCap32) to the 'start-up'-group to ensure that
the available DMA-memory can be allocated by the VIDEO DC1. Alternatively you can e.g. add the line
run=c:\windows\system\VidCap32.exe
to the [windows]-section of your WIN.INI-file.
If your system hangs while configuring the VIDEO DC1 please check, if the selected DMA-channel is
already in use by another device. If so, please change the VIDEO DC1-DMA-channel (available: 5,6 and 7)
