Hey folks, I'm layering a couple of video files, animation+ codec,
using gl.videoplane. so the chain is something like [qt.movie
colormode@ uyvu] -- [gl.vidoplane]
it works great except the people who made the original animation
didn't premultiply the alpha channel (this is their terminology, i'm
just parroting it here because of my general ignorance of alphas in
motion graphics) and a fine while halo appears around the matte.
in final cut pro i can change the alpha type from "straight" to
"white" and the image appears without this fine white line.
re-rendering after selecting this type of alpha matte doesnt seem to
help in gl playback. is there an analgous attribute to this "alpha
type" in gl.videoplane, gl.texture, or anywhere else for that matter?
thanks list. you're best.
