I think it would be really useful and fast with postproduction digital noise, if simple enough.

There were some FFTW-based plugins like DeFreq (?). But it works about good only if you distortion is narrow bandwidth enough (like colour subcarrier). Natural noise is much more complex mixed with useful data and can not be as simply separated. When you run SMDegrain and it blends different frames blocks - it may be equal to special temporal-convolution frequency filter to pass only narrow frequencies and suppress out of band noise. May be same or close idea is implemented in FFT3D plugin via FFT.

That is not natural noise.

That anime was 3D rendered and digital noise added later, to simulate film effect. The bandwidth, as far as my eyes can see, is really limited and mostly visible in darker area, even if light ones are mildly affected too.

[DTL]

Typical examples for narrow band distortions are Aerial interference with analog broadcast or some analog interference at ADC board/device to convert analog to digital. If random special noise is added - it most probable have too wide (flat) spectrum and can not be easily filtered out with narrow band-stop filters.

Would you please address me to where to download them?

Do you know of some model that can keep 1x scale and deblur/antialiasing, to have some anime restoration instead of scaling?

Tried to use Oyster_super.

I have to Crop(128,128,-128,-128) and resize because the image become enlarged and corrupted along the sides and doubles.

Plus, the comment says ## Input: 444 YUV/RGB at any bitdepth (output is float) but it needs to be 32 bits.

Anyone else?

LWLibavVideoSource("INPUT.mkv")
ConvertBits(32).ConvertToPlanarRGB()

Has anyone compared Stabilization Tools Pack with Deshaker 3.1?

[tormento]

The call from xClean:

ConvertFormat(cconv, fmt_out="444", kernel_c=chroma, tv_in=!fulls, cplace_in=cplace)

causes

Script error: NNEDI3RESIZE does not have a named argument "src_width"

and I can't sort out the bug in the TransformsPackMain-2.2.1.

Any idea?

It happens that anime are getting more and more "clean" in the general appearance but if you zoom in the dark areas you can see lot of "pixel fluctuations", perhaps coming from a poor AVC compression strategy, even from BDs. Sometimes it appears on light areas too but it's more rare.

Wanting to cleanup those lurking pixels without ruining the overall quality what do you suggest me?

I have tried with high tr and thsad numbers but all I obtain is to ruin the details without cleaning up the dark areas.

Someone tried it before?

Filter the dark areas with stronger filtering than the brighter areas (or no filtering for the bright)

You can use the LumaMask in the MasksPack

Thank you, nice idea.

And what about “subtle pixel noise” in light areas?

It’s way less noticeable but still there.

The problem is that from film grain noise, digital workflow switches that easily fixable rumor to tiny pixel fluctuations than you can really notice on larger screens.

Not really my idea - people have been doing this for >30 years, pre-avisynth with denoising images. You can find video mask scripts 20 years ago

Use a "subtle pixel noise filter" for the light areas using the mask

Then it wasn't produced correctly. Digital workflows add grain to blend everything in . e.g. CG added to film

Ray-tracing renderers can produce "real" grians by itself.
And most noises in digital era is added without good reason.

Yes, or not - it depends on the settings

Often the "grain" does not end up look like real film grain, but digital noise - not enough iterations and convergence during render

Yes, digital acquisition tends to be clean, especially with good lighting. The grain is added in post. "Dark" scenes are often shot brighter, then adjusted to look "dark" in post

But for film, the CG elements have grain emulation to blend into the film as stated above

Some full CGI animes start to have good enough quality to be almost on par with drawn ones, i.e. Girls band cry.

The problem is that people are so used to grain that they artificially added it with no apparent reason.

Thus, denoising that digital "pixel fluctuation" makes faint details from CGI to disappear.

I uploaded a small clip from that anime, if you are curious to look at what I mean.
