• You can sync lock any number of tracks in any combination. The tracks do not require
matching timecode or common sources and can include multiple video tracks as well as
audio tracks.
• Sync locking affects entire tracks. This means that parallel segments in other
sync-locked tracks are affected when you add, move, trim, or remove material anywhere
in the sequence.
Syncing with Tail Leader
You can add tail leader to the audio or video material to provide a useful visual reference in
the Timeline for tracking and fixing sync breaks across any number of tracks.
Film editors traditionally use standard head and tail leaders for this purpose. You can create
your own leader according to any specification, as described in “Leaders” on page 241.
With tail leader added to synchronized tracks, you can go to the end of the sequence after
making a complicated edit and see whether the leaders are lined up. If they are out of line,
this indicates a sync break that you can measure and eliminate.
To eliminate a sync break when the leaders do not line up:
1. Move the position indicator to the black segment that follows the out-of-sync leader.
2. Select the track, and then click the Mark Clip button. You can measure the break by
checking the IN to OUT duration of the marked segment.
3. Find the point at which the sync was lost.
4. Add or remove frames by using the appropriate edit function, as described in “Fixing
Sync Breaks” in the Help.
5. (Option) As a quick fix, you can enter Segment mode by clicking the Extract/Splice-in
(yellow arrow) button. Drag the black segment at the end of the out-of-sync tail leader to
the location where the sync was lost.
This segment of black, created when the track went out of sync, is the exact length of the
sync break.
Syncing with Locators
Like tail leaders, you can add locators to material in the Timeline to track and adjust breaks
in sync between any number of tracks. You can place locators anywhere in the sequence and
you can add specific notes.
For more information on using locators, see “Using Locators” on page 352.
