Adding Black While Trimming
You can add black filler on either the A-side or the B-side of a transition while maintaining the overall duration of the track and the sync relationships. The system adds a black segment to fill the duration of the trimmed frames.
To add black while trimming:
1.  Enter Trim mode.
2.  Select the transition.
3.  Press and hold the Alt key (Windows) or the Ctrl key (Macintosh) while dragging the A-side or B-side trim roller.
The system adds a black segment without changing the duration of the sequence.
After you add black filler to a video track, you can replace the filler with footage by performing a replace edit. For more information, see Performing a Replace Edit.
