Ahh, Cowboy Bebop. Ask manono!

I think this is called rainbowing. There are some filter against this artefacts, like derainbow or SmartSSIQ. Just search for some keywords. :)

I agree that it is called "rainbow."

I did a quick try at cleaning it. Not claiming it as best way.



BiFrost(interlaced=false,scenelumathresh=1.5,variation=2)
BiFrost(interlaced=false,scenelumathresh=1.25,variation=2)
BiFrost(interlaced=false,scenelumathresh=1.2,variation=2)


Loaded into VDub and using internal "temporalsmoother" set to "5"

Looked good.

For Avisynth only setup, try "TemporalSoften(4,4,8,8,2)"

I find that the Vdub internal TemporalSmoother is better than the Avisynth TemporalSoften. Of course, it requires a color remapping, more hard drive space, etc...

I actually made my "Rainbow killer" using Cowboy Bebop as reference. You can find it:

There are plenty of other great filters out there, but this one did the job nicely for C.B.

Cool. I'll try that out and see how it
works.

Thanks for the help everyone.
