Edit Sync Mode The setting chosen in Setup Menu 221 - Edit Sync Mode – determines which point in the audio material to be pasted or inserted from the clipboard will be used as the sync reference point for the edit. This is a very important consideration, since the end result of the edit operation may be very different depending on the current setting of this menu parameter when the edit is performed.
The two parameters for this menu are Sync at In Point and Sync at Playhead.
When Sync at In Point is chosen as the Edit Sync Mode, the beginning of the region placed in the clipboard (by executing a Copy, Clear, or Cut operation) will be placed at the current In register time code setting when a Paste or Insert operation is performed. This is the mode illustrated in the graphic representations of the Edit functions shown on the previous pages of this manual.
When Sync at Playhead is chosen as the Edit Sync Mode, the location of the playhead relative to the In register is remembered as an offset when the material is placed on the clipboard (by executing a Copy, Clear, or Cut operation). That offset point (rather than the beginning of the region defined in the clipboard) will be placed at the current In register time code when a Paste or Insert operation is performed. The region defined in the clipboard will be placed at the appropriate location relative to the offset amount defined when the Cut, Copy, or Clear operation was performed. The Playhead offset can be before or after the In point of the material placed on the Clipboard. Here are two examples:
Playhead
Clear w/Playhead Before In

This function is most often used to synchronize a point within an audio segment (for example the point of the Doppler shift in a car drive by) to a specific time code point (the place where the car appears closest in the shot).
