Also, what's the codec of the source material?

If it's a highly compressed one (DV, mid-quality MJPEG etc.) then you'll see this staircasing much more clearly when you've pulled your key than on your original unkeyed footage. There is a keyer designed for DV material, that works to smooth out these artefacts, but I can't remember exactly what it's called (DVmatte?).

You could also put a small blur on your matte.

Alternately, as it looks like a CG source, you could re-render your orignal footage to an uncompressed codec prior to doing any further work on it.

Hope that helps,
