I am applying the keyed green screen footage as a track matte to the original footage (without the key) because of the graininess created by Keylight. When I do this, the dreaded matte line appears around the edges of the footage. I have watched the video on premultiplication as well as the video called "Alpha Channel Problems". The issue I am having has to do with the Remove Matte Color effect. When I use this effect, I have to use a gray color in order to eliminate the matte line, and even that does not completely work. If I choose black as the color for the effect the matte line still exists. What am I doing wrong? Is there another way to get rid of that matte line?
