Undo command.
Changing the Duration of a Nested Sequence Ripples Clips
After the Nested Sequence
When you first nest a sequence into another sequence (sometimes known as the
parent sequence), changes in the original nested sequence that affect its duration are
reflected in the parent sequence. For example, if you shorten a clip in the original
nested sequence, the overall sequence duration changes. As a result, the duration of
the nested sequence within the parent sequence is also shortened, and the subsequent
clips in the parent sequence are rippled to compensate for the shorter
nested sequence.
This is quite helpful, since otherwise you’d end up with gaps in your parent sequence
whenever you change the length of one of your nested sequences. This is convenient
when each of your movie scenes is in a separate sequence. After you’ve edited all your
scenes together, if you decide to reedit any of the scene sequences, the changes you
make will automatically ripple items in the entire master sequence.
This nested sequence
replaces the selected
clips.
