-
- Q. Why is my image grainy?
- A. What you see is dithering, a method to "see" more colors (e.g.,
- 16M-color JPG file on a 256-color display). For for outstanding
- JPEG viewing, on 256-color displays, enable Optimal Palette
- option for outstanding JPEG viewing.
-
-
- Q. Why can't I play VideoCD files?
- A. VideoCD (*.DAT) files are MPEG-1 files (*.MPG) and require an MCI
- driver that plays MPG files. Rename any *.MPG file on your hard
- disk to *.DAT; if it plays then you've confirmed a BUS MASTER
- conflict. Remove your OEM Bus Master driver (e.g., Triones) and
- reload the Win95 default PIIX driver (without bus mastering).
-
-
- Q. Why can't I play WAV or MID (MIDI) files?
- A. You must have a sound card and drivers (that come with your card)
- installed. Only MID (MIDI) files with matching instruments
- mapped by your MIDI Mapper can be played.
-
-
- Q. Why can't I play AVI, MOV, FLI/FLC or MPG movies?
- A. You need the VFW (Video for Windows) MCI driver for AVI files,
- QTW (QuickTime for Windows) MCI driver for MOV files and Autodesk
- Animation MCI driver for FLI/FLC files. MPG files need a driver
- from your video card manufacturer for optimal playback. You can
- also try the Shareware MCI driver (VMPEG); check my Web page for
- download links.
-
- Win95 users already have the latest VFW drivers if you installed
- with a typical setup; otherwise, install multimedia components
- from your Win95 CDROM. Win31 users that play AVI files encoded
- with new compression schemes may get an MCI error and must
- download VFW11e.exe (or later) and install extracted files.
-
-
- Q. What MPEG drivers does VidFun support?
- A. It supports all MPEG-1 MCI drivers. Make sure you set VidFun's
- compatibility options from it's Main menu. MPEG-2, MPEG-4, and
- MJPEG (Motion JPEG) are very rare and require hardware-specific
- drivers and/or hardware devices.
-
- With VMPEG, CompCore SoftPEG (bundled w/ Matrox cards), or
- MediaMatics (bundled w/ Stealth64 and NEC machines) driver set:
-
- Safe MPEG Mode=OFF
- Scaleable MPEG=ON
-
- With the Xing driver (bundled w/ many S3 cards) set:
-
- Safe MPEG Mode=ON
- Scaleable MPEG=ON
-
- For best results, users with S3-based cards should
- get/use the NATIVE S3 Xing driver (v1.3 or later).
-
- With the ATI driver (v2.22 or earlier) set:
-
- Safe MPEG Mode=OFF
- Scaleable MPEG=OFF
-
- With the ATI driver (v2.23 or later) set:
-
- Safe MPEG Mode=OFF
- Scaleable MPEG=ON
-
- Interpolation is a bit slow since the Mach64 does not
- support hardware scaling; the Mach64VT does. Switch
- Scaleable MPEG=OFF for smoother viewing.
-
- With all other drivers (e.g., Tseng 4000, Cirrus) set:
-
- Safe MPEG Mode=ON
- Scaleable MPEG=OFF
-
-
- Q. What are "Safe MPEG Mode" and "Scaleable MPEG" options?
- A. "Safe MPEG Mode" uses high-level MCI functions instead of faster,
- low-level function calls and another instance to avoid a system
- lockout if driver crashes; looped playback in slideshows is also
- disabled. DO NOT DISABLE unless sure that your driver is stable.
-
- The "Scaleable MPEG" option, if enabled, will play MPG files
- like AVI or MOV (Quicktime) video; position and video size in
- slideshows is supported. If disabled (default), MPG video files
- will play as non-scaleable animation files (e.g., FLI); the MCI
- driver is responsible for window creation and update (usually
- last position). DO NOT ENABLE this option if you are not sure
- your MCI driver supports variably resized video windows (i.e.,
- any zoom factor, not just 2x or 4x).
-
- If your card does not support scaleable MPEG, don't fret. As
- long as MCI driver does (e.g., VMPEG, SoftPEG, MediaMatics),
- VidFun will use it's feature set. ATI's Mach64 driver is NOT
- scaleable but fast and stable; the new Mach64VT supports scaling.
- Video cards based on S3 (Trio32/64, 864/964) chipsets do NOT
- support scaling. Weitek 9100, Trident 9680 (IBM Aptiva), Matrox
- Millenium, Tseng ET6000, Alliance ProMotion 64xx (NEC xx22), and
- S3 (928, Trio64V+/UV+, 868/968, ViRGE) cards support scaling and
- are usually bundled with an MPEG MCI driver. With other cards,
- check your manual or ask your dealer.
-
-
- Q. Why are total number of reported MPG frames wrong?
- A. Some MPG files stop or loop from middle or continue playing even
- if 'end of the file'. Depending on the way "key" frames are
- encoded and read, the total number of frames reported by the MCI
- device will be wrong. Regardless, VidFun will loop when file
- has stopped and allow random access "beyond total frames".
-
-
- Q. Why is MPG video playing "too fast"?
- A. This problem exists with many MPG files found on the Internet.
- It varies with MCI driver or file encoding. With Xing driver,
- enable "Rate Control" to minimize problem.
-
-
- Q. Why is video playback silent?
- A. Playback of AVI or MOV files with sound requires a sound card and
- installed drivers. Some video files have NO audio; most MPG files
- found on Internet are silent movies. Some MPG files have WAV files
- (with same name) as audio track; VMPEG is the only driver I know
- that plays MPG with synchronized WAV audio. Also, ensure that
- your Volume Control is set correctly.
-
-
- Q. Why does VideoCD playback stop after a minute?
- A. You are probably using the Shareware version of the VMPEG driver.
- Get a registered version of VMPEG or install the MPEG MCI driver
- bundled with your video card or Computer.
-
-
- Q. Why is video playback jerky?
- A. Firstly, make sure your video files are placed on uncompressed
- hard drive. If playing from CDROM, Quad-speed (or better) is
- recommended; in Win95, set maximum "read ahead" buffer and
- appropriate drive speed. 160x120x256 (15 fps) AVI video runs
- smoothly on most 386DX33s; for 24-bit video playback, see below.
-
- Frames fps Type(s) Zoom Mininum System Requirements
- -------- --- ------- ---- ---------------------------
- 160x120 15 MPG x1 486-33 + 32-bit video
- 320x240 30 MOV/AVI^ x1 486-66 + 32-bit video
- 352x240 30 VideoCD x1 486-100 + 64-bit video
-
- ^Cinepak compressed w/ less than 300 kbs xfer rate; Indeo
- compressed files and xfer rates >300 kbs need faster CPU.
-
-
- Q. I want to upgrade my system. What do you recommend?
- A. For extended hardware discussions surf over to
-
- http://www.rose.com/~lgozum/bang4buck.html
-
-
- Q. Can I design a slideshow for different video modes ?
- A. Yes, provided the target display is larger than the display mode
- you designed it on. Write the script in 640x480 video mode for
- widest audience. Remember that (1) FLI/FLC (or non-scaleable
- MPG) playback is not resizeable. (2) WAV and MID playback needs
- a sound card. (3) Graphics, video/animation in user positions
- will not be in the same spacial location as those set to "mid".
-
-
- Q. Can the slideshow wait for a keypress before showing next slide?
- A. Yes. Pressing [spacebar] terminates the wait/delay added to a
- particular slide; set the wait/delay to maximum. If you enable
- View|Preferences|Show Slide Control, each slide advances only
- when you click advance button (you can "jump" to any slide too).
-
-
- Q. What causes erratic multimedia slideshows/screensaver errors?
- A. Running multi-track multimedia slideshows can "stress" your
- system. If slideshow/screensaver plays for hours then crashes,
- HEAT is the problem; we have confirmed this on a 6x86 P150+;
- no problems have been reported with Cyrix/IBM 6x86 P120+.
-
- To diagnose memory timing problems, write down ALL your CMOS
- CHIPSET settings and enable BIOS DEFAULTS; diehard "tweakers"
- can adjust individual settings until reliable settings are found.
- Also, update your Win95 system with Microsoft's SERVICE PACK and
- other updates (downlable from their Web site). Video and audio
- card drivers can also affect reliability (see next sections).
-
-
- Q. Is there a problem with ATI/Mach64 card?
- A. Quicktime for Windows may crash if the following entry is
- absent in your [Macx] section:
-
- DeviceBitmap=OFF
-
- Get latest drivers from ATI (www.atitech.ca); v2.23 or later.
-
- The Win95 MPG driver 2.23 sometimes "unregisters" itself;
- using in Screensaver is not recommended.
-
- Q. Is there a problem with Matrox Millenium card?
- A. Older drivers caused mask to appear as solid white block in True
- Color (24-bit) video mode. Get latest Win95 drivers (v3.14 or
- later) from Matrox (www.matrox.com). In Windows 3.x, use the
- Mask|Inverse option to correct 24-bit mask problem.
-
- With VMPEG MCI driver, DISABLE DCI in "Video Configuration".
-
-
- Q. What do I do about MCI errors when playing FLI/FLC files?
- A. Most likely you did not install the MCI drivers for FLI/FLC
- playback or have an incomplete setup. Use Media Player to test
- playback. Check your SYSTEM.INI and WIN.INI files.
-
- In SYSTEM.INI file:
-
- [mci]
- Animation1=mciaap.drv
-
- In WIN.INI file:
-
- [mci extensions]
- fli=Animation1
-
-
- Q. What do I do about MCI errors when playing Quicktime MOV files?
- A. If your video card seems incompatible with MOV playback, backup
- your QTW.INI file then modify the following sections' entries to
- look like this:
-
- [Options]
- VideoOptimize=DIB
-
- [Video]
- Optimize=DIB
-
- If you get MCI errors during playback, backup your SYSTEM.INI
- and check for following entry under the [mci] section (drive and
- directory may vary with your system).
-
- QTWvideo=C:\WINDOWS\SYSTEM\MCIQTW.DRV
-
- Also, check your WIN.INI file for the following entry under the
- [mci extensions] section.
-
- MOV=QTWvideo
-
- To get the latest QTW drivers visit Apple Computers' Page
-
- http://www.apple.com
-
- QuickTime for Windows (QTW) 32-bit (v2.1.1 or later) does not
- not support MCI; the Win95 Media player will not recognize it;
- the same seems to be true with QTW 16-bit (v2.03 or later).
- However, VidFun will play QTW MOVies if QTW 16-bit is properly
- installed. VidFun supports 32-bit video and will recognize a
- QTW 32-bit version that supports MCI (e.g., via "thunking").
-
-
- Q. Media player reports "settings changed by another program"?
- A. If you associated multimedia elements with VidFun instead of
- the Win95 Media player, it will report that. Click "No" if you
- still want VidFun to be default multimedia player; click "Yes"
- and Media player again becomes the default multimedia player.
-
-
- Q. Is my video card incompatible with video playback?
- A. Change Windows video mode to VGA 640x480 (16 colors). Video
- files should play (jerky, slow and grainy). Test other video
- modes; if specific modes don't playback correctly, install
- updated drivers from your card's manufacturer. In Win95,
- you can also set "Graphics Performance" to NONE (at System
- Panel) to test driver compatibility.
-
-
- Q. Is my audio card incompatible?
- A. Generally, you shouldn't have a problem. On a Pentium 100 or
- faster, the chances of incompatibility increase. With Creative
- Labs' Vibra16 card, make sure you get the latest Win95 drivers
- (4/96 or later); older drivers had some nasty interactions.
-
-
- Q. I don't want certain VidFun File association, what do I do?
- A. If you don't want to associate specific FILE TYPES such as *.CAL
- fax files which have the same extension of CALendar data files,
- uninstall VidFun to restore all your previous associations.
- Reinstall from original self-extracting archive and "check" only
- desired FILE TYPES to be associated, in setup dialog.
-
-
- Q. Can I import unsupported graphics (e.g., GIF)?
- A. If other Windows apps can decode it, copy it to the Windows
- clipboard; from VidFun select Edit|Paste. Also, use other apps
- to save to one of VidFun's supported formats (e.g., BMP) too.
