Synchronizing at key positions

If you have added key positions to the clip(s) (see Adding key positions), you can synchronize performances at every key position for which the labels match. For example, if you consistently use the label "impact" when the club hits the ball and "top" for the position that corresponds to the end of the back swing, it will be very simple to re-synchronize two clips at "impact" or at "top".

You can synchronize clips by matching key positions with the same label. To do this:

1.	Load two clips in split-screen.

2.	Switch to the Key Positions view. Say that both clips contain a key position with the label "impact" at the position where the club hits the ball. Labels must exactly match (see Editing key positions to find out how to edit key position labels).

3.	Double-click on the key postion "impact".

This method allows very fast re-synchronization at every matching key position.

If you add key positions to a clip by importing them from a reference clip (see Importing key positions), it will be very easy to synchronize both clips because labels are imported from the reference clip and so exactly match.

If the clips contain multiple key positions, you can synchronize them at a particular position by a double click and navigate through the other key positions by a single-click and observe the relative position of the performers. For example, if you have a key position at every gate of a giant slalom it will be easy to see the distance gained or lost by a skier between each gate.
