TRACK MATTES
Hi All,
I’m editing a show and have been given an animation that needs to be layered over the opening montage. The animation is kinda like those masks that isolate James Bond in the titles to the Bond films, but kinda 3D-ish.
I’ve been given a color pass and a matte of the animation.My color pass has the foreground elements in pink and white (they’re supposed to be that color) and the rest of the image area is green. The edges of the circle are supposed to fluctuate between pink and white when layered over the matte.
I’ve got the montage on V1, the matte on V2 and the color pass on V3. Composite modes are NORMAL for V1 and V2, and TRAVEL MATTE LUMA for V3.
Now i see my montage through the center. The problem is that the edges of the circle are still green. So i’ve CC’d it and got the greens out etc. But it just doesn’t look the way it should.
The FLAME guy says thats the way he always gives his stuff out and that when the color pass and matte are layered correctly. the edges will turn pink.
Does anyone have any suggestions ? I’m sorry if i haven’t explained the animation very well, but it’s just kinda weird looking.
Sandeep.

If I’m reading the post correctly, you’re seeing a few pixels of the foreground image bleeding in around the edge of the matte?
You might try applying a bit of Matte Choker to the matte image but that might do something the Travel Matte blending function since effects are processed before blends. But I never use travel mattes, I always set up straight alpha or luma keying in a nested sequence.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

seems like the common symptom of a premultiplication issue. In a movie file with embbeded alpha, you can switch form straight to premultiplied iwth black (FCP calls this “Black”) in the clip’s properties, but i’m not sure you can deal with it when using a track matte.
Maybe you could try to use the “Image mask” effect instead. It doesn’t work for moving mattes, tho. If it doesn’t work, you should do it in After Effects or Combustion.
