You can include elements from multiple video tracks in an edit sync group. The following illustration shows a multitrack that
includes front and matte elements for two layers and a background. Create an edit sync group for both layers so that any edit
you perform to a front, for example, does not throw off the timing of the corresponding matte. By creating an edit sync group
for V1, V2, V3, and V4, you maintain the timing for the front and matte layers while working on the timeline.
If you are manually creating edit sync groups, the first element you select becomes the master sync element. If the edit sync
groups were created automatically during input, the element used as the master sync element depends on the assignment of Primary
and Secondary video tracks:
- If a track to be included in the edit sync group is assigned as the Primary video track, the first element on the Primary
video track automatically becomes the master sync element for the edit sync group.
- If a track to be included in the edit sync group is assigned as the Secondary video track, and no other track is assigned
as the Primary video track, the first element on the Secondary video track automatically becomes the master sync element.
- If no tracks to be included in the edit sync group are assigned as either Primary or Secondary video tracks, the first element
on the highest video track in the stack becomes the master sync element.
To create an edit sync group with multiple video tracks:
- Select the element you want to use as the master sync element.
- Hold down Ctrl and click the other video elements that you want to include in the sync group.
- Press Ctrl+E.
The sync group is created.
