Under Video Processing Format , select either 8-bit or 10-bit to indicate
3
the bit depth you want to use for processing video in a sequence. When the
video output for an HD sequence is downconverted to NTSC or PAL, or
when you are working with a 1440×1080i/p sequence, the video processing
format will be set to 8-bit .
¦ Note If you select a 10-bit video processing format, you'll be able to capture
clips to Matrox 10-bit uncompressed format only. If you also want your
previews to be rendered to 10-bit format, make sure that you configure the
Matrox uncompressed codec to 10-bit for your video previews as explained
in "Defining your video preview settings"
Use the Preroll/Postroll frames for audio scrubbing sliders to specify the
4
number of audio frames you want to be played before/after the location of
the current-time indicator when you scrub a sequence. This lets you hear
more audio to help you better identify sounds when scrubbing. For example,
if you set the number of preroll frames for audio scrubbing to 3 , you will
hear the audio for the current frame and three previous frames when you
scrub a frame in a sequence.
¦ Note
To return a slider to it's default setting, click its D button. This button
is available for all sliders in the Matrox dialog boxes.
