Can you edit all parameters in Clay for the results?

Sure go ahead and tweak all you want.

It would be perfect if the noise is removed.

Also results are weak in terms of upscaling.

You're right again.

I tried many AviSynth denoisers but can't get a result without loss of detail.
Can I see your effort please?

try

SMDegrain(6, 400, prefilter=6, ContraSharp=true, RefineMotion=true, plane=4, limits=false, DCTFlicker=false)

or

TemporalDegrain2(postFFT=4, fftThreads=2)

[ingoldie]

By the way, the results without denoise filter I use

What do you think about denoising effort of the results?

I wonder why both of you don't try and test. I'm lazy and just suggestions. You need to try before ask someone result

Both are very bad. Detail loss, multiple deformities, etc.

Can you screenshot where detail lost between original and denoised video? And deformities relate interlaced not noised. Denoised script can't fix interlaced, you need use Deinterlaced script to fix that

[ingoldie]

Open two files via the same AvsPmod and view them sequentially to see all the difference between "Results without denoising" and denoised results ("SMDegrain Result", "TemporalDegrain2 Result 2")


SMDegrain Result



TemporalDegrain2 Result 2




There is also a general loss of detail.

[kedautinh12]

Can you compared with original video???

[ingoldie]

Here is the Original upscaled(lanczos4resize(1024,768)) to compare with SMDegrain Result

https://www.mediafire.com/file/dvv6k...%2529.avi/file

As I told open two files via the same AvsPmod and view them sequentially to see all the difference.

Compare here, this is sample you share me not sample above

[kedautinh12]

And can you share me sample before upscale?? I think you need Deinterlaced before upscale to get progressive frame

[ingoldie]

Do you mean the following files in the first post?

By the way, when I play the following video, deformities occur in the places I marked.

When I upscale(lanczos4resize(1024,768)) or zoom 200% the following Original(512x384) files in the second AvsPmod and compare them with the Results without denoising, I can't see any problem except noises.

If you pay attention, the results look very natural and I don't know how I can remove the noises without loosing this naturalness.
