A gap is an empty space in the timeline. On a single layer, a gap is displayed as a hole in the multi-layer timeline. A red X is displayed in the Player when the positioner is located on a gap. Gaps are also displayed as 'GAP' in the Source Timecode field.
Gaps can be modified like other clips. They can be trimmed by using Ripple Start and Ripple End mode (see ). Their length can also be increased or decreased by modifying the clips around them. Gaps can be selected, copied, or deleted.
