I've searched long and hard for something to feed quality video into winamp for manipulation. Unfortuantely, all I've found are these:
psychosis isn't bad., I haven't done a lot of testing with this because it's a full plugin, not an AVS preset panel.
pr0n is an AVS preset panel, but because of my crappy webcam (Connectix Quickcam VC) it's occassionally flakey and the last thing i need during a performance is the pc going into an eternal sleep.
there is one other AVS preset panel that I know of but can't find right now (I'm at work...) I'll update this post in the very near future.
