if you want to just remove all the greens and reds in the video, why not texture it on something that has no red/green components (like a [square] with [color 0 0 1]) - default texturing does a per-channel multiplication with the underlying color (so if the the channel "red" is zero for the geo, than the you won't have any red-component in the displayed image either) if you want to burn CPU-cycles, you could also use [pix_gain] and set the gains to "0 0 1"
This is very efficient on CPU. But, if one needs to add saturation or contrast in Gem, he needs to use [pix_levels] or [pix_gain] for saturation and [pix_curve] for contrast, right ?
