Final Cut Express: Flip a Video Clip I'm sure this is trivial to do, but I've yet to find the right filter to Flip a video clip in FCE 4.

For example, see what happens at the 0:42 mark in this video  (Night Stand HD Pro)

I see box flips, or page flips, but how can I just flip a single layer around an axis?
I guess I'll answer my own question:

After a lot of searching last night, I found a YouTube video that demonstrated a method to animate the flip of video clips using a free plugin called MultiSpace from idustrial revolution.
