Move edit points to the playhead
You can adjust selected edit points in the Timeline, either as a ripple edit or a roll edit, using
keyboard shortcuts.
1 In the Timeline, select the edit point you want to adjust.
Selected end point
Note: For a roll edit, select both sides of the edit point with the Trim tool.
2 Position the playhead or the skimmer at the point in the Timeline to which you want to move
the edit point.
Skimmer
3 Choose Edit > Extend Edit (or press Shift-X).
The edit point is extended (or shortened) to the playhead or skimmer position.
The clip’s end point is extended
to the skimmer position, and
subsequent clips ripple right.
In the example above, if you selected the end point of the clip, subsequent clips in the Timeline
are rippled accordingly. If you selected both sides of the edit point with the Trim tool, the right
clip is shortened (with a roll edit) and no clips ripple.
