Installation
============
- For video software to work properly, Windows NT 4.0 Service Pack 4 or later
must first be installed. To obtain a Microsoft Service Pack, contact
your system vendor or see the Microsoft Web site (www.microsoft.com).
- The Matrox Video Tools setup program stops if a Matrox video capture card
supported by this video software isn't properly installed in your computer,
or if recent Matrox display drivers aren't installed.
- If you see a message indicating that DirectX Media can't be installed, it
may be because DirectX Media is already installed on your computer. If you
see this message, click "OK" and continue the software installation.
- To remove Matrox Video Tools software, click "Start" -> "Settings" ->
"Control Panel" -> "Add/Remove Programs" (double-click) -> "Matrox Video
Tools" -> "Add/Remove". You should restart your computer immediately after
you remove the software.
Notes, problems, and limitations
================================
- Matrox Video Tools requires Windows NT 4.0 Service Pack 4 for dual-CPU
computers.
- The Matrox Video Tools software doesn't support the Matrox add-on for
DFP (Digital Flat Panel) monitors.
- On some systems you may experience problems with jerky video file playback.
This can especially happen at larger video frame sizes (352 x 480/576 and
704 x 480/576). To help avoid this problem, make sure your hard disk is
using DMA (Direct Memory Access). For most computers, a DMA driver is
available for Windows NT 4.0 (for example, the "PIIX Bus Master IDE" driver
supports many computers). For more information on how to get this driver,
contact your system vendor.
- For optimal performance of capturing/playback, we recommend that DMA is
enabled from within Windows NT. By default Windows NT will not enable DMA.
You would have to obtain a utility called DMACHECK or similiar utility in
order to enable DMA support under Windows NT.
- Because of a limitation in Microsoft Video for Windows, video files you
capture are limited to a 2 GB size. (The Matrox PC-VCR Remote program lets
you work around this limitation by creating consecutive video files.)
- When recording more than 2 GB of video with the Matrox PC-VCR Remote
program, there may be a small gap between video files. The amount of
video missing depends on the performance of your system.
- Recording RGB video files with a Matrox G100-MMS card at a data rate
over 2 MB/sec will result in a high number of dropped frames. (The playback
of the resulting video will be jerky.)
- Because of a limitation in Microsoft Video for Windows NT 4.0, there's a
maximum number of frames (cumulative) you can capture with an RGB capture
setting. The number depends on the amount of main memory in your computer
and the speed of your computer's CPU. If the maximum number of frames is
exceeded, you may get an error message stating that video can't be captured
because the data rate is too high or your disk is full. (You may get this
error message even though your disk is not full.) If this happens, close
the capture program you're using and then restart it. If your video capture
program lets you allocate a video file size before capturing, you can use
this feature to avoid this limitation.
- If your display is using a 32-bit color palette, you may notice lines in a
video window while viewing TV tuner input or MJPEG video files. To avoid
this problem, try reducing the video window size to a size that is smaller
than the resolution of the original video (size "x1"). Also, you can try
reducing the vertical refresh rate of your monitor to below 85 Hz. (For
more information on changing monitor settings, see Matrox PowerDesk online
documentation.)
- Using a DOS window or changing display settings (resolution or color palette)
may cause problems if, at the same time, you're playing back or recording a
video file, or using the Closed Captioning feature.
- PC-VCR Remote may stop responding or playing back files while playing back
multiple video files using the looping option. To restore PC-VCR, click
"Stop" and then "Play", or close and then restart the program.
- After you click the "Auto Scan" button on the "TV Setup" property sheet of
Matrox PC-VCR Remote, live video may not be properly displayed in the
current video window. To restore the video window, simply select "LINE" or
"FILE" input, then reselect "TV" input.
- If you have a Matrox Marvel G200 or Rainbow Runner G-Series card, Matrox
video software can't be used with a 640 x 480 display resolution. This is
because of a limitation in the version of Microsoft DirectDraw used with
Windows NT 4.0. If you're using this display resolution and you have one
of these cards, change your display resolution before using a video program.
- If you use the Matrox QuickConnect program with a Matrox G100 MMS card and
a 640 x 480 display resolution, the navigation buttons may be cut off by the
bottom of your display. Before using QuickConnect, make sure your display
resolution is higher than 640 x 480.
- There are maximum video window sizes for viewing MJPEG video files or live
video ("TV" or "LINE" input). These maximum video window sizes depend on
your display settings and graphics card. For more information, see the
"Display information" section of your Matrox video capture card manual.
Note: Not all Matrox products include MJPEG hardware. If your system doesn't
have MJPEG hardware, MJPEG controls are unavailable.
- Because of a limitation with the DirectDraw 3 software used with Windows
NT 4.0, Matrox Video Tools software only supports multi-display mode
with the Matrox Productiva G100 MMS cards.
- You may experience problems if another Matrox graphics card is installed
with a Matrox G100 MMS card.
- The Matrox VidCap driver is designed to work only with 32-bit programs
(programs designed for Windows 95, 98 or NT). You can't use 16-bit programs
(programs designed for Windows 3.1) with your Matrox video editing
hardware.
- Only one program at a time can use Matrox video editing hardware. Before
starting a video program, close any other video program that may be running.
- With Matrox Video Tools software installed on your computer, you may
experience problems using video editing software. To recover from
these problems, save your work and then try restarting your video editing
software.
- MediaStudio updates are available at Ulead's Web site (www.ulead.com/tech)
These updates should improve stability and performance. The following entry
can be added to ulead32.ini for improved MediaStudio performance.

- You may experience problems with a video capture program if it's not closed
before logging off a Windows session.
- When you drag-and-drop video files onto the PC-VCR Remote icon, long file
names are converted to the old 8.3 DOS-naming style in the PC-VCR Remote
menu window and on the video window title bar.
- Suspend mode is not supported by Matrox video software.
- With Matrox G200 graphics cards and Matrox Video Tools for NT, you can
view video while previewing TV channels in PC-VCR window. (Matrox Video
Tools for Windows 95/98 doesn't support this feature.)
- If Microsoft Media Player stops responding, try clicking on the Windows
desktop background, then clicking on Media Player -- this may restore
control.
- While playing back an MJPEG video file with Media Player, you may experience
problems if you double click on the title bar. To fix this, download an
updated version of Media Player from the Microsoft Web site
(www.microsoft.com).
- After installing Matrox Video Tools, the default tuning settings on the
"Video" property sheet of PC-VCR Remote are 0% (even thought the video
window displays properly). To restore the appropriate levels, click "Default
Tuning". (To access the "Video" property sheet, first select "TV" or "LINE"
input.)
- Ensoniq Sound Cards: Certain models of Ensoniq sound cards (for example the
SoundScape Vivo 90) will lose audio when seeking or stopping and restarting
any video file. This happens when double-clicking on a file or using
DirectShow through Media Player. To avoid this problem, use the Matrox
PC-VCR Remote to view your video files.
- ESS sound chips: Certain sound card models equipped with the ESS audio chip
(for example the ESS 1878 found on laptops) may experience a loss of
audio-video synchronization when playing back video files. Video will be
late compared to audio whenever pausing and restarting the playback. To
correct this problem, click on the PC-VCR Remote playback status bar to jump
to a particular area in the file.
