Preroll Type a value in the box to specify the number of seconds of preroll
Video Capture should use for SDI batch capture.
When you click Capture Clips , on the Clip Log tab, Video
Capture will seek to a point prior to your Timecode In setting
determined by the number of seconds you enter in the Preroll box.
Video Capture will begin playback at the preroll location, and switch
to capture when it reaches the timecode you specified in the
Timecode In box.
Notes:
n Batch capture will fail if there is not enough lead-in time.
The deck must be able to find the timecode that equals
the Timecode In value minus the Preroll value.
n VITC and HANC timecode sources require less preroll
than RS-422, as RS-422 needs time to synchronize
timecodes with video frames.
