I am interested in learning how to create something like this on my Mac? http://i4.tinypic.com/6tumv4g.gif So I have found that you need to take these steps to get your video footage from youtube http://www.youtube.com/watch?v=jZVKkNGZZQw but then once you have the video, how do you separate the scene and convert it into a motion gif file like the one I opsted above? I am running Leopard with imovie, but have not really used it yet. Any tutorial links or advice would be appreciated. Thanks!
