The Roll edit tool is used to trim two contiguous clips at the same time. The out point of the first clip and the in point of the second clip will be trimmed simultaneously, changing the duration of both clips without moving their positions on the timeline.
When you position the mouse on the connecting line between two clips it will change the roll edit icon. Clicking and dragging with the mouse will change the out point of the first clip and the in point of the second simultaneously.Surrounding clips are unaffected.
Roll edit Viewer
The Viewer updates with useful information during a roll edit:
The out point of the first clip is shown on the left and the in point of the second clip is shown on the right. As you perform the roll edit both previews will update to show the new edit points.
