Wow everyone is making this too complicated. After you rip the video, put it in womble, take the section you want and get rid of everything else on the timeline. Export that clip then load it into AE, in AE (I might have pro, not sure) you can highlight a selected area (select the area you need from the clean frame and save it). Apply it as another layer on top of the clip (the area where you selected will stay the same as the frame you selected it from, everything else in the clip [aside from the area you selected] will stay the same as it normally would for that frame) mark in where you want this to start, move the slider a few frames to where you want it to stop then mark out. Drag the slider back to the beginning and hit play just to see if you did it right, then export it. Then import it into womble and put the clip where it belongs. These are pretty basic and generalized directions, but once you start to mess with it I swear you get the hang of it in no time, I swear, this was the first type of thing I had to do in AE and it was fro someone elses edit and I was a total noob but after only a coupla hours everything turned out perfect! TheForce.net has some tutorials for this under the fan films section (thats where I learned) but if you can't figure it out, I'd be glad to walk you and/or anyone else through it, my AIM screenname is the exact same as my username on these boards!
