Understanding Sync Relationships
Between Multiple Linked Audio Items
Up to 24 audio items can be linked to a single video item in the Timeline. As a result,
some complex sync relationships may result if you slip more than one of a clip’s audio
items (for information on slip edits, see “
Slipping Clips in the Timeline ” on page 325).
These are easily managed using the same out-of-sync indicators described earlier.
When you create a merged clip, or link multiple items together in the Timeline, the
video item is considered the anchor item to which the sync of all other linked audio
items is compared. If you’re linking audio clip items without a video item, then the
topmost audio item in the Timeline acts as the anchor item.
In the following example, three stereo pairs of audio items are linked to a single video item.
Moving a single pair of items out of sync results in a single out-of-sync duration, with out-
of-sync indicators with positive and negative durations in both the video and audio items.
