That effect is easily done in Adobe Premiere.
I made this <a href="http://coolantx.hn.org/media2/demo-it.avi">demo</a> in about 10minutes. Is there something more to this 3-layer process that Iam not seeing? Such as you don't have Premiere?
Just it's great if you need all those editors to do neat stuff, but I just used one editor, Premiere, to do that effect....
