Under the menu point
Options\Video Format
you will find another very important parameter
for recording video sequences. The setting Image Format lets you determine how many bytes
to use to save one pixel of the TV picture. As before, the more bytes per pixel you have, the
greater the data yield when recording. For that reason, take a close look at the following table:
Image Format
What it means for the Recording
32-Bit RGB
4 bytes per pixel in the TV picture are saved
24-Bit RGB
3 bytes per pixel in the TV picture are saved
15-Bit RGB
2 bytes per pixel in the TV picture are saved
BTYUV
Low data yield through compression
YUV9
Low data yield through compression
YUV12
Low data yield through compression
NOTE:
Recordings of video sequences made with the BTYUV, YUV9 and YUV12 image formats, can
only be played back on systems, on which the TV card's drivers are installed. This is because
these image formats work in conjunction with special compression formats matched to the
television hardware. When you prepare a video sequence for use on your system, you can
easily fall back on these special compression formats. If you want to give your video clips to
other PC users, then you should use a RGB format!
