Okay so I have two videos. One is a background video (scenery) and the other is a action video (layered on top). I want to give the effect that the action video is fitting into the background video, it's a window (see screen shot): http://imgur.com/a/vbIqX
I have circled in red the 4 corners where I want to skew the video so that it fits in that window. How is this done? Currently I can only drag the entire left side or the entire right side. I should be able to drag the corner freely to fit in the corners? Thanks!
