Under Video Processing Format , select either 8-bit or 10-bit to indicate
5
the bit depth you want to use for processing video in a sequence. In some
cases, such as when the video output for an HD sequence is downconverted
to NTSC or PAL, the video processing format will be set to 8-bit .
Under Preroll/Postroll Frames for Audio Scrubbing , use the sliders to
6
specify the 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.

choose to disable certain features and specify how you want your Motion
effects to be processed. For details, see

Under Realtime Indicator Threshold , drag the slider to set the threshold at
9
which Matrox Axio determines that a segment in the Timeline panel is
realtime. Drag to the left to set a lower (safer) threshold, or to the right to set
a higher (more aggressive) threshold. For example, if you find that Matrox
Axio does not identify any segments as being non-realtime (that is, with a
red bar) and you have dropped frames when you export your sequence to
tape, you can set a safer threshold to force more segments to require
rendering and avoid having dropped frames. Alternately, if you find that
some segments are identified with a red bar but they don't have dropped
frames, you can set a more aggressive threshold.
