Can't amke primatte work properly

[user_deleted]

Am work with an awful green screen. trying to put a CG still image on a live action telly in a room (with someone in front of it). Have got a reasonably clean line around theh person but the edge of the screen was a bit off (also a lot of the periphweral action is either transparent fopreground or background). So created a rotoshape of the screen and subtracted a rotoshape of the person to get a garbage matte. Then inverted screen roto to make a holdout matte.But when I wire everthing up i get a lot of holes in my original image and one of teh mattes seems to cut into the image and I get some? colour comming through the holes in the image. Can anyone help?

I can hardly imagine your setup without actually seeing the image, but if you do have a clean outline, why don't you just draw a rotoshape around it (outbounds), invert it, and feed it as garbagematte?
If you also have transparent areas inside the character, you should cover them with another rotoshape that would go into holdoutmatte.

Primatte hates QuickTime. Export to an image sequence first.
