string mode - processing speed (and quality) - slow/slower/slowest - slowest

int strength - processing strength - 0-255 - 255

float clipstren - value clipping strength - 0.0-10.0 - 5.0

bool post - spatial postprocessing - true/false - true
 
"Slow" mode might cause chroma ghosting on edges. Slowest is the safest, but might not be as effective as slow.
 
Explanation of clipstren: this works like value boosts in mfToon, it's the gamma correction of the mask ^^'. Lower values give more variation, but less strength.
 
You need [[Deen]], [[MaskTools]] and [[MSmooth]].
 
Like before (and probably ever again), I don't check colorspaces cause I'm too lazy, and my function always outputs YV12. Who needs another colorspace anyway. I'm still kinda sad about the fact that [[Layer]] and [[Mask]] don't work in YUV (cause of the lack of an AYUV colorspace), so alas I have to do 2 colorspace conversions, namely to RGB and back. (Note Wilbert: note that there is a Layer/Mask equivalent working in YUV nowadays, so the script could be adjusted without those colorspace conversions.) The luma luckily doesn't have to be touched (and I do [[MergeChroma]] to ensure that), so that minimizes conversion errors.
 
Please test if this is any better or worse than existing derainbowers. A discussion can be found [http://forum.doom9.org/showthread.php?s=&postid=321859#post321859 here].
