Doesn't ChromaShift left/up equal Luma shift right/down and vice versa
Hmm, luma are chroma are independent. So, I don't understand this remark.

I was looking at the avi of Defiler, in this thread: http://forum.doom9.org/showthread.ph...ht=chromashift

The suggestion of Belgabor doesn't make any sense to me:

ChromaShift(u=-2, v=2)
# u: green -> blue
# v: green -> red

IMO, the solution should be:
shift green ~ 2 pixels to the right
shift blue ~ 2 pixels to the left
shift red ~ 1 pixel to the right

By controlling only u and v, you can't shift all three colors with ChromaShift (which is needed in this case, I think). But, maybe I'm totally incorrect ...
