Several of the used tools don't work with RGB32.

Basically it should be possible to separate the channels, process them individually and merge back together ... but that's an insane effort. The script right now is already ultra-slow when called on the full 1080p video. With channel splitting, it'll be roughly 4 times slower, if not worse.

Also, I'm not even sure in how far this kind of processing is a valid thing to do on the alpha channel.
