Need a matte generated from an image or video shot on a black background? Knoll Unmult will create an alpha channel from any image shot on black. This is particularly useful for generating alpha channels for flares rendered on black or video or filmed media that is shot on black like cloud tank, lighting, or water droplet on glass—like the shots done in Episode 47 of Red Giant TV (Aeen in the video above).

Knoll Unmult works in After Effects CS3, CS4, and CS5 (64-bit).
