Inserts and Overlays

I learned how to insert a video into another video. So the time in the video wont be wierd, the girl is doing her jump on the horse when the 1 1/2 seconds is still going it was just like just a little brake. so you dont really miss anything. They are diffrent because the insert is cutting the first video and the overlay is running both videos at the same time. So when the girl is looking the horse is still jumping there is no pause this is the overlay. The insert Pauses the jump to have the girl look then replays the horse jumping. You may use insert to help show a persons emotions when somthing is happening.
