Apple Final Cut Pro 7 - Manual (Page 700)

A ripple edit is a one-sided edit, meaning that only an In or Out point of a single clip item
is affected. All clips following the shortened or extended clip are moved accordingly in
the Timeline, so ripple edits affect both the trimmed clip and the position of all subsequent
clips in the Timeline. This is a much more major operation than simply trimming an
individual clip’s length.

Important: Ripple edits can be dangerous if you are trying to maintain sync between clip
items on different tracks, since all of the clip items on one track may move forward or
backward while the clip items on other tracks don’t.
To perform a ripple edit, you use the Ripple tool.
Ripple edits are done
using the Ripple tool.
Note: You can select an edit point in the Timeline when you are using the Ripple tool.
You can also open a sequence clip in the Viewer when the Ripple tool is selected by
double-clicking the clip in the Timeline.
Which Clip Items Move in the Timeline After a Ripple Edit?
Clip items with In points later in the Timeline than the edit point (or edit points) you are
adjusting will move, or ripple, after you perform a ripple edit. All other clip items remain
in the same position in the Timeline.
Take special care when performing ripple edits with complex edit point selections on
multiple tracks. To make sure you understand how an edit affects the clip items in your
sequence, you can undo (Command-Z) and redo (Command-Shift-Z) your edit several
times to compare the sequence before and after the ripple edit was performed.
