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 a recent Matrox display driver isn'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
================================
- Tip: If your computer has more than one hard disk, you may get better
results if you play back or capture video files with a disk other than the
one where the Windows swap file is stored. (The Windows swap file is
usually stored on drive "C:".)
- 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.
- Suspend mode is not supported by Matrox video software.
- 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.
- If Microsoft Media Player stops responding, try clicking on the Windows
desktop background, then clicking on Media Player -- this may restore
control.
- 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.
- 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.)
- 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.
- 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.
- 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.
- You may experience problems with a video capture program if it's not closed
before logging off a Windows session.
- If you're using Matrox Video Tools with a dual-CPU computer, make sure that
Windows NT 4.0 Service Pack 4 (or later) is installed.
- 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.
- 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, a data rate over 2 MB/sec may result in a high
number of dropped frames. (The playback of the resulting video may be
jerky.) To avoid jerky video with RGB video file recordings, use lower
frame resolution and frame rate settings.
- 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.
- Matrox PC-VCR Remote may stop responding or playing back files while playing
back multiple video files using the looping option. To restore PC-VCR Remote,
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 your Matrox video capture card has MJPEG hardware (for example, Marvel
G200 or Rainbow Runner G-Series), 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 experience
this problem, change your display resolution before using a video program.
- If you use the Matrox Quick Connect program with a Matrox MMS card and a
640 x 480 display resolution, the navigation buttons may be cut off by the
bottom of your display. Before using Quick Connect, make sure your display
resolution is higher than 640 x 480.
- 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 the Ulead Web site
(www.ulead.com/tech). These updates may improve stability and
performance. Also, to improve MediaStudio performance, the following entry
can be added to your "ulead32.ini" file:
[HardwareAcc]
AlwaysKeepLastFrame=1
- With Matrox G200/G400 graphics cards and Matrox Video Tools for Windows NT
4.0, you can view video while previewing TV channels in the Matrox PC-VCR
window. (Matrox Video Tools for Windows 95/98 doesn't support this feature.)
- 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).
- With the Ulead MediaStudio Pro video capture program, make sure the number
of video buffers is set to 30 or less. Otherwise, you may get an error
message while capturing MJPEG video. To access the video buffer
setting, click "Capture" -> "Video" -> "Advanced".
- To record video with the Microsoft VidCap32 program, click "Capture" ->
"Video", select your settings, then click "OK".
- This version of Video Tools supports multi-display mode. However, if you
have more than one graphics card in your computer (all of which must be
supported by the Matrox display driver), video support may be restricted
to certain graphics cards.
(1) If more than one Matrox graphics card in your computer has video input
support, video input is only supported with the first video-input-
supporting graphics card detected by your computer. (The order that your
computer detects each card is partly determined by the expansion slot
each card is in.)
(2) The viewing of Matrox hardware-supported video (for example, live
video) only works among displays controlled by graphics cards using the
same slot type (PCI or AGP). Also, if the graphics card with video input
support is G100-based, video support only works with that graphics card.
If all the graphics cards in your computer are using the same expansion
slot type and none of the cards is G100-based, video playback is
supported on all displays.
Note: In multi-display mode, video quality is usually better on the
display that has video input support associated with it.
- With this version of Video Tools, a digital flat panel monitor is only
supported with the Matrox G400 flat panel add-on. With a G400 flat panel
add-on, Video Tools only supports the maximum display resolution of your
flat panel monitor.
Note: Without Video Tools support, no program can use Matrox video input.
- If you have DualHead-supporting Matrox graphics card and you're using a
TV for your secondary display, you may not be able to enable "DualHead
Clone" mode while a video program is running. To avoid this problem,
close all video programs before enabling "DualHead Clone" mode.
- You may experience problems if you're capturing large video files (larger
than 2 GB) and your computer doesn't have enough system memory. To capture
large video files, we recommend that your computer have large amounts of
system memory (128 MB or more).
