Avid Xpress Pro/ Media Composer and understanding sync lock
The sync lock feature allows you to maintain sync among several tracks while adding, moving, trimming, or removing frames in a sequence. For example, if you insert an edit into one track that is sync locked to a second track, the system automatically inserts filler in the second track to maintain sync between the two.
You activate sync locking by clicking the Sync Lock button in the Track Selector panel to display the Sync Lock icon. You can also switch all sync locks on or off by clicking the Sync Lock All button.
Here are some of the things you need to be aware of when using the sync lock feature:
1. Edits performed in editing, Segment, or Effect mode override sync-locked tracks.
2. Sync locking applies to single-roller trims only because dual-roller trims do not break sync.
3. 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.
4. 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.
I use sync lock in all of my editing and is it very important to utilize it once you have a completed sequence.
