If you watched episode 47 of Red Giant TV, aside from being humbled by the amazingness of Tiny Inventions, you may also have caught a notation about Knoll Unmult – a free plug-in for removing black backgrounds and generating mattes. Here is a 3-minute excerpt from the tutorial that explains what it does and how it works:
iPod/iPad-Friendly version on Vimeo.
Since then, we’ve had a lot of requests for a CS5-ready version. So, rather than waiting until it came up in our release schedule, our engineering team got cracking, and pushed it forward – just for you! No joke.
It’s still FREE, and you can get it here.
Have fun!

In which case is this different from “Set Matte”-effect or making a Luma-Matte based on it self?

@Twinkle:
I just downloaded it to test. It is slightly different, to a degree that I think it makes it more than trivial.
Applying unmult on an image, then placing a black solid behind it, makes it appear as the original image did.

Hi Guys.
I can’t get unmult to install on CS5.5. Is there any reason for this? It just doesn’t show up in AE no matter where I try and install it.

Hey,
Having the same problem with CS.5 its not showing up in the effects tab any solutions to this.
I put the plugin into /Applications/After effects 5.5/Plugins
