This is an example of an overlay edit. You can use this during when an action is going on so it doesnt disrupt the flow of the action. i decided to overlay the second clip where i did so it seemed like the girl was excited about the jump the other girl just preformed. The difference between an overlay and an insert edit is that in an overlay edit the original video keeps playing along with the second video in order to keep the time flow going and to make the video look normal. An insert stops the original video and while the first video is paused it plays the second video. In this case the overlay works better because it doesnt stop the action that is being preformed and keeps everything flowing.
