I'm seeing a phenomenon I don't know how it's called. Color dancing up and down. I attach an untouched snippet. How can I take care of it?
Here's also a picture, a zoomed close-up

Thanks. But I'm using avisynth, not vapoursynth. Also, sadly in your attachment there are still some rainbows in the tree there...
While we're at it, in the source there's not only dancing rainbows, there's also a general dancing of the image, don't know how to put it better. Is there a way to stabilize it?
Did you try
DeRainbow(8) #adjust the strength (lower value=stronger)
Is your snip.mkv an upscaled and re-encoded VHS capture or other source? If so, it's better to start from the original capture or unprocessed source.

About DeRainbow, it depends on mipsmooth which is 32-bit only. I can't use it in my 64-bit installation
Re: the clip. What you say is very possible but I have little information about the original source, and I don't have access to it, so this will have to do.
I'm using a 64bit MipSmooth here without a problem,... (http://avisynth.nl/index.php/AviSynth%2B_x64_plugins)users currently on my ignore list: deadrats, Stears555
Thanks! I often forget to check that page, I just saw the plugin here http://avisynth.nl/index.php/MipSmooth#Spatio-Temporal_Denoisers which is 32-bit only.
It does help a lot (had to go down to 3 for the DeRainbow value)
