^^ Scratch that! Apparently you need to load DGDecNV via the avs LoadPlugin method, for DGDenoise to work.

EDIT: And allow me this opportunity to again express how happy I am with DGDecNV. I used to use KNLMeansCL (with haf.QTGMC), but DGDenoise goes so much faster!

Again, glad you like it and thanks for your kind words. Note that DGDenoise is spatial only. Some people prefer also to do temporal. I have often asked for a sample that shows the need for temporal but nobody ever provided me with one. I'm still willing to add temporal but only if the need is clearly shown.

Well, for VHS tape captures I have been using
Code:
DGDenoise(strength=0.04)
temporalsoften(4,4,8,10,mode=2)
fluxsmoothST(3,3)
Not sure whether a temporal component in DGDenoise would have been a substitute for the temporalsoften() and fluxsmooth()

Hard to say without a sample that shows the actual need for temporal processing. Can you provide one?

Bluray source:

I don't know how it looks with DGDenoise since I don't have DGDecNV or a nvidia card, but I doubt It will be as clear as with a spatio-temporal filter.

Thank you, ChaosKing. What spatiotemporal denoiser and settings would you use for this sample?

Such source can be denoised without major detail loss using double denoiser technique: mv.Degrain(tr=1, thsad=48...120) and prefilter (for example, dfttest with tbsize=3 and sirma=1..7) on super-clip. That's my common solution on gainy animes.

Full script would be appreciated. Also, what frame rate would you get for (say) a 1920x1080 stream with that denoising?

Just a quick test - I use vapoursynth, ryzen 1700, rx480 gpu


3.5 fps with knlm.KNLMeansCL(d=2, a=6, s=5, h=2.2)
9fps TemporalDegrain2(clip, degrainTR=3, postFFT=0)

this is more grainy, but the grain ist much more stable
50fps haf.SMDegrain(clip, tr=3, thSAD=800, prefilter=clip.flux.SmoothT(temporal_threshold=6))


There are avisynth equivalents for the used filters.

Edit
this looks actually very good (noisefree) and is still "fast"
15fps haf.MCTemporalDenoise(clip, settings="high")

I don't think I've actually ever used MCTemporalDenoise with 'settings=high', as even 'medium' is very, very strong. Unless the presets are attenuated some in VS. They aren't, are they?

I think they are pretty close to the avs version.
