So at the moment I'm using iMovie, but I really don't think it can do this. Basically I'm looking to isolate a small part of a gif/video and drop it on top of a video. Any ideas what application I can use? I've tried looking for iMovie tutorials on this, but they just seem to be split-screen videos which isn't really what I'm wanting. Any ideas which apps I can use and how I can do it? Can it be done through iMovie? Heck, I can't even figure out how to do effects as crudely as Birdemic!
