Why Synchronize Playheads?
Reasons for using playhead sync include:
 Automatically opening sequence clips in the Viewer to quickly make filter
adjustments (for example, adjusting each sequence clip’s Color Correction filter).
 Using the Viewer as an alternative to the Trim Edit window, to look at prospective
new In and Out points for a sequence clip. Although the end result is the same, this
method provides a different experience than editing in the Timeline or the two-up
view you see in the Canvas while trimming.
 Temporarily syncing a Browser clip to a sequence, using any sync relationship
you want.
 Enabling real-time multiclip editing. When the Multiclip Playback option is selected,
the Open playhead sync option is automatically selected.
