Hi!

I'm trying to fix these three kind of chroma noises Video link - 26MB (https://drive.google.com/open?id=1ufys65bD0Ywv0x9NmoFKAO0j9XtGpDOw).
In the video you have in the top row the U channel and in the bottom row the V channel. First column even fields, second column odd fields.


I'm quite confident that there isn't "one size fits all"-filter, but maaaaybe..! :p

1) Are these kind of chroma noises some kind of "known noises"?
2) Is there some good motion compensated chroma noise removal?
3) These are results of a median of multiple captures. So I'm confident that the noise is actually on the tape and was not introduced by me, but is there a way to remove this kind of noise from the source? Is the comb filter useful for this case?

Thanks!
I'm learning a lot thanks to this forum :-)

Can you upload a few seconds of the original capture, rather than your '3 kind of chroma noises' clip?
Did you try avisynth filters for (chroma, flux …...) noise reduction?
