Overwrite parts of your project
In an overwrite edit, one or more source clips overwrite any clips in the primary storyline or a selected storyline, starting at a range selection start point or at the playhead or skimmer position. No clip items are rippled forward, so the duration of your project remains the same.
Overwriting media is different from replacing it. Overwriting works with range selections only, not entire clips, and it is not constrained by clip boundaries. Use an overwrite edit when you want to edit media for a specific span of time, rather than specific shots.
Note: You can use three-point editing to make overwrite edits. For more information, see Three-point editing overview.
Overwrite clips in the Timeline with clips from the Browser
If there are multiple source clips in the selection, the clips will appear in the Timeline in the order in which they were selected.
To define where you want the overwrite clip to start in the Timeline, do one of the following in the primary storyline or a selected storyline:
Choose Edit > Overwrite (or press D).
The source clip appears in the primary storyline and overwrites any clips for the duration of the source clip.
Note: If you use the keyboard shortcut and the skimmer is present in the Timeline, the edit will occur at the skimmer position.
To overwrite from the playhead back, so that the overwrite clip’s end point (rather than its start point) is aligned at the target position, press Shift-D.
