Program Monitor during a ripple or rolling edit
A rolling edit trims an adjacent Out point and In point simultaneously and by the same number of frames. This effec-
tively moves the edit point between clips, preserving other clips’ positions in time and maintaining the total duration
of the sequence. Pressing Alt when you begin to perform a rolling edit ignores the link between video and audio
(known as an
L-cut or J-cut ).
In this rolling edit, the edit point is dragged earlier in time—shortening the previous clip, lengthening the next clip, and maintaining the
program duration.
A ripple edit trims a clip and shifts subsequent clips in the track by the amount you trim. Shortening a clip by ripple
editing shifts all clips after the cut back in time; conversely, extending a clip shifts the clips that follow the cut forward
in time. When you’re making a ripple edit, empty space on one side of the cut is treated as a clip and shifts in time
just as a clip would be. Pressing Alt when you begin to perform a ripple edit ignores the link between video and audio.
In this ripple edit, the edit point is dragged earlier in time—shortening the preceding clip and the total program duration.
