A slip edit allows you to change a clip’s start and end points simultaneously. Whenever you arrange clips in the timeline so that edit points line up with musical beats or other fixed sync points in a movie, you want to keep your clips in position to maintain the alignment.
What changes when you edit with the slide tool?
The Slide Edit tool lets you slide a clip forward or backward between two other clips without changing the selected clip. Rather, you shift the in- and out-points of the adjacent clips to accommodate your clip’s new position in the project. Once again, the overall length of your production does not change.
