Using the Gang Playhead Sync Option
You can lock the playhead in the Viewer to the playhead in the Canvas and Timeline so
that they move together while scrubbing through clips. This is known as ganging the
clip in the Viewer window to the sequence in the Canvas and Timeline windows.
When this option is selected, the offset between the current position of the Canvas/
Timeline playhead and the current position of the Viewer playhead is maintained as
both playheads move together. This mode is useful for editing operations in which you
want to set In or Out points in the Viewer using durations defined by items or markers
in the Timeline as your reference.
