It's my opinions that that noise is on the original film, so it should remain in the video. If you really want to remove it you can use a filter that includes spacial noise reduction as well as temporal noise reduction. Try something like MCTemporalDenoise(settings="very high") instead.
Also, I just noticed the video needs a little more cropping at the top and right of the frame.

Replacing Temporaldegrain by MCtemporaldenoise
From its doc:
# recommendation:
...
# 3. if more denoising is needed try postFFT=1 with postSigma=1 and postDither=-1, then tune postSigma (obvious blocking and banding of regions in the sky are indications of a value which is at least a factor 2 too high)
# 4. if you would need a postSigma of more than 2, try first to increase degrainTR. The goal is to balance postSigma and degrainTR. However, do not increase degrainTR above 1/8th of the fps (at 24fps up to 3).
# 5. if there are any issues with banding switch to postFFT=3
...
# - postFFT, if you want to remove absolutely all remaining noise suggestion is to use 3 (dfttest) for its quality or 1 (ff3dfilter) is much faster but can introduce banding. 2 and 4 are GPU based versions.
# - postSigma, increase it to remove all the remaining noise you want removed, but do not increase too much since unnecessary high values have severe negative impact on either banding and/or sharpness
# - postDither, positive values are used as parameter for dfttest (values above 2 can remove preexinsting banding), negative values indicate 16 bits FFT processing (to be used only with postFFT=1 or in case of strong paranoia regarding banding)

I installed the filters asked by MCtemporalDenoise but i have this message?
Do you have an idea what i am doing wrong?

The error message doesn't make sense. The first 135 lines of that avsi file are comments. So there can't be an error on line 3. Did you check the contents? Don't just rely on the name.

Try mctemporaldenoise with the gradfun2db turned off, and not being used by making GFthr=1.00 instead of its default which will deband the video, and destroy more detail.
mctemporaldenoise(sigma=2, sharp=false, radius=1, ecrad=1, AGstr=0.5, GFthr=1.00) # Increase sigma to 3-6 to get stronger denoise if you want
It might get it working, but you should still try to fix the underlying issue.Last edited by killerteengohan; 6th Apr 2021 at 15:09.

Yeah, like Jagabo said, it uses a much higher sigma which is very destructive to details and will smudge out grainy artifacts more to look cleaner. It will look cleaner, but you are wiping out detail. If you want smeared out garbage to get it cleaner looking, then by all means, raise the sigma higher and use DNR that's overkill. It's your call. I just typically try never to go above 6, and even then I feel 6 is too strong.
