Hi again. I have a clip which contains lots of rainbowing. The clip is stored in a zipfile and can be accessed *here* (http://rapidshare.com/files/125547793/rainbowclip.zip.html) via Rapidshare.

The clip is a snippet of a raw, unprocessed analog capture (30 frames long, 29.97fps interlaced, YUY2 colorspace, Huffyuv compression, no audio).

I can't seem to get rid of the rainbow seen in the brown shawl worn by the old woman in the foreground. I've tried Derainbow(), and TComb v2B2 without success. I'm hoping that maybe someone has a function (optimizable for this clip) or a script that will eliminate the rainbow without messing up the chroma very much.

As always, I'm grateful for the assistance that this community provides. :thanks:

I had just the same problem recently. Derainbow(1) removed the majority of rainbows, but there were still large ones. Especially on transitions. I guess those just can't be removed, but they are not so noticeable in real time.
