Recording to a video file
1 Click the LINE button on the PC-VCR Remote. You should see video in the PC-VCR
Remote video window; if not, see “Before you record to a video file”, page 34.
2 Click Record ().
If you click Record once, PC-VCR Remote will record to video file until you click Stop
( ) or run out of disk space. If you click
Record again, PC-VCR Remote will record
for 2 minutes; click again and PC-VCR Remote will record for 4 minutes; and so on.
Recording settings
The maximum frame size and rates you can select with
the
Recording settings slider are based on the currently
selected capture settings (see “Capture options”) and
the disk where the video file will be created. Higher-quality capture settings generally
require a disk that can store information faster. PC-VCR Remote determines how fast your
disk can store information by checking the results saved by the
Matrox HD Benchmark
program.
Capture options
On the Recording property sheet, click the Capture Options button to select your video
capture type:
MJPEG – Click this button to use hardware-based Matrox MJPEG (Motion-JPEG) video
compression. Video files you create with this button selected are smaller, and as a result, your
disk can store longer videos and handle more video at a time. When your disk can handle
more video at a time, you get
higher-quality video file recording and playback.
Video files you create with this button selected are still Audio Video Interleaved files ( *.avi ),
but only someone with a Matrox video editing card and its software drivers can use them.
This is because Matrox video editing cards have special hardware to decompress MJPEG-
encoded video files. You can adjust the image quality of Matrox MJPEG digital video by
moving the
MJPEG quality slider in the same dialog box.
