How do I sync 2 videos so they play in time?

1. Once your videos are loaded, click on button ‘A’ to the right of the video slider (scrubber). 
2. Now move video A to a key point in the action.
3. Repeat with the steps above video B.
4. Now press the AB button to lock them together. Remember they can only be in sync at the 2 points you chose.

If you play the video, events later in the video may be out of sync if the action is happening at different rates.
