This is an example of an overlay edit. An overlay edit places a clip on top of an original clip while the original clip is still playing. The inserted clip does not effect time in the original clip. To do this, you edit the clip in the source panel. Then you drag the edited clip to the timeline where you want to place it. I decided to edit the 2nd clip where I did because you see the lady is paying attention right after the first jump, then goes back to the horse jumping a second time.



The difference between an overlay and an insert edit is for an insert edit, when you place a clip in the timeline with an original clip, time in the original clip stops and cuts to the inserted clip,then picks up where it left off. This type of edit interrupts time. You would use an overlay edit when you want to keep time realistically going, while you’d use an insert edit when you don't want, or need continuous time. In this case the overlay edit works better because the lady in the second clip is watching a continuous action.
