About Ripple Edits and Sync Relationships of Clip Items
on Other Tracks
When you perform ripple edits, it is fairly easy to cause linked clip items across tracks to
go out of sync with each other. This usually happens when you perform a ripple edit on
one track while other tracks are locked, so the clip items on that track can’t move in
sync after the ripple edit.
For example, if you have video clip items edited to the rhythm of a music track, rippling
clips in the video track moves them out of sync with the music. In this case, you
probably shouldn’t use the Ripple tool. Instead, you can change the length of a clip
item without moving other clips in the Timeline. If you shorten the clip item, this
means there will be a gap in the video track that you need to fill, but at least all of your
other clips won’t be out of sync with the music.
Final Cut Express HD tries to prevent you from performing ripple edits that will cause
linked clip items to go out of sync. Final Cut Express HD assumes that any overlapping
clip items should maintain the same sync relationship before and after an edit.
Furthermore, a ripple edit cannot cause any clips to overwrite other clips.
Before the edit,
clips are in sync with
markers on the
audio tracks.
After a ripple edit, the
sync relationship
has changed.
