Red line artifacts?

[kuchikirukia]

I have a telecined DVD that has residual combing after IVTC and these red bits in the linework and elsewhere.

(both untouched, just different frame, both should be "progressive")

Looks a bit like rainbowing to me but Tcomb doesn't touch it.

Definitely not rainbow
Chroma-shift, maybe?

Chroma-shift, maybe?

Yeah, seems to be. I can't make heads or tails out of what it's doing, though.

From the apothecary grandma: Here. (http://forum.doom9.org/showthread.php?p=1582950#post1582950)

That doesn't seem to touch the red lines. It fixes some patches of blocks in the background here and there, but also introduces a few more artifacts. And it seems to change the tint of the whole scene.

Try with DeRainbow or BiFrost.

EDIT: or try Vinverse or Mergechroma(vinverse()).
