Chapter 32 Performing Slip, Slide, Ripple, and Roll Edits 467
VII
In the example below, Final Cut Express HD 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 Express HD 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 Express HD does not attempt to ripple the
second music clip (see “ Locking Tracks to Prevent Edits or Changes ” on page 314).
 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 468.
...Final Cut Express HD won’t allow
the edit because the second
music clip in tracks A3 and A4
cannot overwrite the first music
Although your intention
is to only ripple the
selected clips...
