help to identify the artifact on fast motion frames

[dr-rainbow]

Hello, tell me please the name of this type of artifact. This is not a simple graininess or noise, such effects appears only in fast motion frames. Do you know some filters or scripts avisynth that can remove it without loss of image clarity and quality?

I tried many Denoisers, but they degrade detail on the background.
Simple "blend fields" clean up well the dirt, but seriously affects image quality.

Try reducing qcomp and see if x264 will do your blurring for you.

The first one looks like it could be an intentional part of the CG render. The other two look like compression artifacts (interlaced mode?).

Yes, source is Mpeg2 ntsc (interlaced)

I think Vinverse (http://avisynth.nl/index.php/Vinverse) is good for reducing the visibility of the tiny combs, but it may not do much for the blockiness.

Have you tried QTGMC's denoising (http://avisynth.nl/index.php/QTGMC#Noise_Bypass_.2F_Denoising) capabilities? I'd be surprised if that doesn't take care of most of those artifacts.

Vinverse with default settings sstr 2.7 skips a lot of dirt.
Decrease sstr improves quality, but blurs the details.

QTGMC denoising really perfectly copes with these artifacts.
I used it only for deinterlacing before.

Thanks for the help!
