I like to create my character animations in Poser 7 and then add them as foregrounds (via compositing) to movies in a video editor (Final Cut Pro in my case). Keying (in the video editor) is really tricky, however -- I'm never sure what the best background color to use in Poser to get the cleanest knockout, though I suppose it may vary according to the Poser character(s) I'm using. The standard Poser gray-brown works okay, but not perfectly. The supposedly superior (for keying) blue or green backgrounds often leave tricky edges. Which is best? I need cleaner keying! Second, I recall someone talking about generating alpha channels in Poser as the best way to composite a Poser character animation in a video editor. Anyone know how that might work? SS
