automatically captured to multiple files; OMF

is captured to multiple files when you set an
option in the Capture Settings dialog box.
Capturing to multiple media files has the following advantages:
• You can create longer clips whose media files would otherwise exceed the file size
limitation of 2 GB.
• You can group all drives with the multiple file options, enabling the system to capture
long clips continuously; for example, satellite feeds.
• The system makes more efficient use of drive space, particularly when capturing
long clips.

For media file management purposes, any clip whose media exceeds the 2-GB limit has
more than one media file associated with it.

Best Available Control
Track
Your Avid editing application uses the control track to determine the preroll point.
• If there is not enough control track for preroll, the system adjusts the specified
preroll time to accommodate the amount of valid control track available.
• If the adjusted preroll time is too short to sync lock at the IN point, the system does
not capture the shot and displays an error message.
After the system adjusts the preroll to the individual shot, it returns to using the
user-specified preroll time until it needs to adjust the time again.
Use this method if you know there are timecode breaks and want to capture material as
automatically as possible. Because the system does not use timecode, it might
Standard Control Track Your Avid editing application uses the control track to determine the preroll point.
If there is a break in the control track, the system stops capturing and displays an error
message.
Use this method if you know the control track is continuous or if you want to
determine if there are breaks in the control track.
