Linking and Unlinking
When you add an asset to your sequence that includes multiple tracks, the segments on those tracks are linked together by default. If you move a segment to a different position in the timeline, the associated segments tracks generally move with it (unless you take steps to modify that behavior). When working with a Sequence, you can sever the relationship between the segments by unlinking them from each other. After you unlink the segments, each behaves independently from the other by default.
Alternatively, you can link segments that were previously unlinked or even link segments together that had no prior relationship. For example you could link a video segment from one asset with the audio segments of a different asset.
Linking and unlinking changes are not saved with the sequence. If you load another sequence in the Asset Editor or reload your sequence in a different user session, the segments revert to their original associations.
To unlink or relink audio and video segments:
1. Do one of the following to define your selection:
Click a segment in the Sequence Timeline to select it.
Ctrl+click two or more individual segments.
2. Do one of the following to either unlink or link the segments:
Right click on your selection and select Unlink from the context menu to disassociate the selected segments.
Right-click on your selection and select Link from the context menu to link the segments together.
After you use the link or unlink commands, you cannot use Undo to revert the action.
