This might not make it into the final "WinDV-style app" I am working on; it takes a bit long (~20 seconds of work on a decent laptop per second of footage).

So far it works, and retains the footage losslessly, except for the portion that is changed of course.

It's done by temporal video inpainting, not just cropping or blurring the line away. It looks at motion and information in neighboring frames, then tries to reconstruct the damaged strip using surrounding frames as references. Only processing the affected bottom strip part not the whole image

Please. https://forum.videohelp.com/threads/421210-For-the-love-of-pixels-Denoising-degraining-in-AviSynth-Please?goto=newpost Thu, 01 Oct 2026 17:54:54 GMT Looking for help getting ANY decent denoising/degraining working in AviSynth+.
And please excuse that this is 50% rant (not at anyone here) and 50% plea for help.

Soooo, I'm not really a newb when it comes to working with video/audio. Used Adobe stuff for a LONG time (until they finally p'd me off so much that I refuse to sub them any longer). And many other video and photography tools over the years. I work in tech and am comfortable with the fiddly, tweakable nature of many "tech" and software things. But I *am* fairly new to AviSynth+. Despite that I've picked up AviSynth+ scripting quickly and I'm able to do a lot with it. Helps that I have experience with other "scripting" and coding things.

I've went down every rabbit-hole I can find, followed every tutorial I could find, and nothing but nothing but nothing has enabled me to use ANY of the commonly referred-to and recommended denoising functions/scripts out there on interwebs. Put all the files/plugins into the folders I'm told they go in. Accounted for x86 vs. 64bit (it's 2026, of course I'm using 64 bit AviSynth+). Downloaded every dependency I think I need when I get errors related to those. Basically done "all the things" that I can find/read that I'm to do. Only to get things like "Ok great, now you have that but you STILL need THIS." "Ok thanks for adding THIS but now you need THAT.", to paraphrase. To say this has been frustrating is an understatement. It shouldn't be this hard.

I'm told such-and-such functions should already be included with certain installs of AviSynth+. Yet I get errors. Errors related to dependencies. Parameter errors with claims that such-and-such parameter doesn't exist, even when said parameters show up in AvsPmod's context bubbles when entering the values for a known plugin. (I think I know why that happens *sometimes* but not all the time.) So I don't know what I might be doing wrong, if anything. Maybe it's something stupid, but I've been pretty thorough in my R&D and troubleshooting. To no avail. Don't get me started on the state of Wiki's and documentation for some of this stuff. Despite a general knack for figuring things out this has stumped me.

So my long-winded plea is simple: Can anyone help me out with procuring what ever it is I need to use any decent denoising and degraining solutions in AviSynth+ specifically? All the files that I need in whatever folder(s) I need to put them in? Anything like that?

Because I'm either still missing something despite my best efforts or something's not working correctly. The de-noiser(s)/de-grainers don't have to work miracles, have CUDA acceleration or be best-in-class, although any of those things are welcome (RTX 3090 in the box). They just need to be adequate for my tasks at hand.

May the Laser Horn Katana of Destoroyah in his final form spare the kind soul that can help me.

"In the time you spent writing this you could have figured it out." I wish.

I know I am opening up myself to potential abuse here (LOL!), but opinions, thoughts, suggestions from more experienced people is never a bad thing.

I have just completed a lot of experimenting on the attached snippet. I have utilized:
-- deflicker
-- spot removal
-- stabilization
-- brightness and contrast
-- (some) frame interpolation
-- sharpening
-- upscaling.

I have not touched the audio yet (which is my area of expertise and I'm not worried about it).
I also know I will have some individual frames to touch up manually that I didn't do for this example.
But this is my starting point for the project.

Thoughts welcomed!

Thanks,
Joe

Is there an order of preference? I think the big question is: interpolation before or after upscaling, but if there are other experienced opinions I would welcome reading them. Thanks!

When I try to read the disc, I get bad sectors, and the game won't install because some files are unreadable. (tried disc images and some recovery programs)
I read somewhere that this happens because the laser has no reflective layer in those spots and passes straight through. And I read somewhere about fixing CDs with painting over them with something, but now I can't find source. Is that true?
Can this be fixed by painting over the holes? Maybe with nail polish?
(Btw, the disc isn't very valuable, so I'm willing to experiment with it,
and the disc is not scratched too much on bottom side...) ]]> Restoration SmurfRecorder https://forum.videohelp.com/threads/421131-how-to-repair-holes-in-official-dvd-label-side
