Quartz Composer and embeded Movies

Hi Richard,
I know this isnt what you would normally want to do, but I'm trying to mask a movie using the least no. of layers.
I have a quartz composer file that I want to use to mask out sections of a movie that is playing in qc, this works fine and considerably better than trying to compress to a codec that supports alpha channels! Its a stationary matte so I thought Id give it a go, but catalyst only doesnt play the embeded movie (via image with movie) I dont need playback fx etc, just to mask the movie.
Is this a workable idea? Or any other ideas that can keep it on one layer?

Cheers

Chris

AAhhhh,
easier than I thought, mask layers in quicktime pro, fantastic, just ignor this post!!!

mask layers?

i never tried to use this.

Can you send me your movie?

Or write here how you need this?

You could also say what you tried to do in qc.

Maybe other people might be interested.
