Chapter 18 Performing Slip, Slide, Ripple, and Roll Edits 335
III
In the example below, Final Cut Pro won’t allow you to perform a ripple edit because
the second music clip in tracks A3 and A4 would either need to be shortened, or would
overwrite part of the first music clip in order to stay in sync with the clip items in V1,
A1, and A2. Since the ripple edit cannot force the second music clip to overwrite the
first music clip, Final Cut Pro warns you that the ripple edit cannot be performed
because there is a clip collision on track A3 (and A4).
There are three ways to solve this problem:
 Lock tracks A3 and A4 so that Final Cut Pro does not attempt to ripple the second
music clip (see “ Locking Tracks to Prevent Edits or Changes ” on page 132).
 In addition to selecting the clip Out points in tracks V1, A1, and A2, you can also
select the first music clip’s Out points in A3 and A4.
 Instead of selecting the first music clip’s Out points, you can perform an asymmetric edit
by selecting the clip Out points in tracks V1, A1, and A2, and the second music clip’s In
points on tracks A3 and A4. This causes the first clip to be shortened from the Out point
while the second clip is shortened from its In point. For more information about
asymmetric editing, see “
Asymmetrical Trimming With the Ripple Tool ” on page 336.
...Final Cut Pro won’t allow the
edit because the second music
clip in tracks A3 and A4 cannot
overwrite the first music clip.
Although your intention
is to only ripple the
selected clips...
