TemporalDegrainV2

[ErazorTT]

If I may enter the discussion here. I have checked the worst of all grainy film (300) and there at scene changes I must say that, yeah perhaps there is a very slight increase of remaining grain but I doubt this will be seen when not at 400% zoom.
So please also just try this:
TemporalDegrain2(degrainTR=2)
or even
TemporalDegrain2(degrainTR=3)

With increasing TR the degraining capability increases but the impact of scene changes decreases. So 3 cleans more than 2 which cleans more than 1 but the impact of a scene change is pretty strong for 1 less so for 2 and only minor for 3.

So to be very much independent of scene changes you could use 3. Then perhaps there might be too much cleaning for your taste, but in this case you could then mix some of the original back into the resulting clip, like that:
TemporalDegrain2(degrainTR=3, postMix=25) [postMix was broken before release 2.3.0 so you'd need to grab this newest one]

Meaning that 25% of the original will be mixed with 75% of the filtered result.

I am just looking at scene changes here and not at what VoodooFX discribed as "flicker" frames. These singular flicker frames basically represent 2 scene changes, one just before and one just after that fliker frame. These will be always very hard to deal with. There is simply not enough information to figure out if the things shown are grain, noise, or actually part of the image. Only way there would be a neuronal network which was trained on the noise during the movie and which is then applied to these singular frames. I have no idea but this sounds a lot like what I just described: http://www.avisynth.nl/users/vcmohan...NeuralNet.html

I saw people using ScSelect in this thread, and it prompted me to make and post this mod.
(I was never a big fan of ScSelect, it makes too many false detect mistakes)

EDIT: Script removed.

I wanted to point that FFT3DGPU requires mode to be 1 to utilize ow and oh. Also precision should be set to 2 to match the CPU version. According to the author, ow must be even but that won't be the case when grainLevel is set to 1.

One more thing, I don't think multiplying ppSAD1 and ppSAD2 when DCT=5 is a good idea. With default setting I noticed a huge banding and artifacts on scene change. The colors are also inaccurate. Using different grainLevels didn't help.

It got better when I removed the multiplication code. See:

Does those artifacts propagate into frames before scene change?

First of all: Many thanks for your script!
I am although running in an issue:
I need to use TemporalDegrain2 multiple times and it throws an exception about "Multiple QTGMC Calls". I found out that QTGMC provides an option to pass the name of the variables it should us or that it should reuse the existing variables. Is there anyway to pass that to your script as your script internally uses TemporalDegrain2?
Thanks for help.

I did the following in TemporalDegrain-v2.2.1.avsi:

# changed
# from ReplaceGlobals = false
# to ReplaceGlobals = true
# to solve QTGMC error "Multiple calls to QTGMC, set PrevGlobals="Replace" or read documentation on 'Multiple QTGMC Calls'"

I only share link for ErazorTT when he online he will catch it. I got last ver when Asd-g released it

[kedautinh12]

As I could observe BM3D is better at motion estimation and probably also at denoising.

[kedautinh12]

fmtconv available avs+ now, maybe replace dither

I moded TemporalDegrain2 use BM3D, details in description

Still waiting for ErazorTT

[coolgit]

TemporalDegrain2(degrainTR=1, postFFT=4, postSigma=2, fftThreads=8) produce a slight shift in colour and weird frame blending during 1st and last frame of scene changes.

The orange/brown colour not suppose to be there.

Upload those images to imgur or you'll wait forever for approval.

[Sangen]

I wonder why it takes so long for approval here

[Boulder]

Sometimes the best way to get them approved is to report the post and ask for the approval

[coolgit]

Changed the links as post 195 is still pending approval.

Impressed with the denoiser!
