I've seen that in recent years there's been a lot of discussions about AI upscaling, but most of what I've seen is upscaling of pictures, and some new and extremely expensive 8k tv that it seems can do it quite well from 4k to 8k.
What I'm wondering is if there's any software that allows to have a good upscaling of old videos (with horrible resolutions like 320p or 480p) to something more decent. I'm obviously not talking about things that just convert the resolution without improving it, but of some AI software.
Is there anything like that right now?

Yes and no. Preface I'm not some kind of software of hardware engineer, but I like to keep up on things. The AI upscaling of video is like this: If you take an SD video, say from a video tape, and play it on a big screen tube TV, it'll look OK. If you play it on a modern HD TV, it'll look a lot crappier. The AI upscaling makes the video look a lot better on a modern screen (even 8K), as if you were watching it on a big tube TV. The technology will eventually exist to upscale much more realistically, but we're not there yet (as in no-can-do).

If you're looking to get software to batch process a bunch of old video through, you could do that, but I think you'd be really disappointed. Someone spending multitudes of hours (using very expensive computers) remastering a single video could produce results where you'd say, wow, that looks pretty good. But otherwise, no.

Interesting question though. And it is sad that so much old porn is not cared for. When upscaling technology does get insanely good, there will be just a small fraction of porn source material to upscale.

thank you for the reply Zingerbrook.
In any case the upscaling technology is (at least for pictures) already very, very good, I'm thinking especially about Enhancenet, able to transform a blurry mess of pixels in a very detailed photo. The point is that in that case it's a photo. And I don't even know how much time is requested to do that, which is a crucial point I guess.
But It certainly would be great to see some old porn movie that nobody cares to remaster in a better resolution.

Enhancenet is definitely interesting. From what I understand, the issue with video is enhancing each frame in a way that is consistent with the previous frame. But I'm sure the technology will move rapidly along.

Although Iím not directly involved in the area, hereís something I know:

picture upscaling doesnít work as in the movies (Enhance - Enhance - Enhance). Thereís only a limited amount one can do, simply because there isnít more information other than guesswork.

video upscaling on the other hand has a major advantage: you can use the surrounding frames to enhance each frame. So from 10 blurry images that show similar, but not 100% identical stuff, you can make 10 sharper images (and so on).

You can think about it this way: in one image you see a blurry black spot. besides a sharp white circle. In the next image you see a sharp black square and a blurry white spot. Assuming those two images are from one and the same object, you can now make two enhanced frames, and you know there is a black square and a white circle on both of them.

no, there is none. Up-scaling is a gimmick used to sell you newer TV's.
Any upscale or remaster done by a producer of videos is done from source footage
which is to re-encode at a higher bit-rate than the previously released video
there is no way to upscale consumer end product video to some thing "decent".

^ Not to argue, but...well, actually yes to argue...AI upscaling (as opposed to the crap non-AI ordinary upscaling) is not a gimmick. The result is potentially excellent quality merely not perfectly accurate to the original image. The technology really is quite cool.

The best you'll get is MadVR:

This is a bit off topic, but I'm now reminded of SVP, the Smooth Video Project. It does frame interpolation. I love high frame rates, especially for typical porn scenes. For some kinds of video it doesn't make sense, but for a vast majority of porn it's great. I wish the whole world would move on to higher FPS standards soon.

SVP (easily found through Google) is great but takes a lot of processing power, or time if you're rendering a new file, but the results are very good.

^ Google it. There is one example. I have also literally seen a couple of other examples (not online). It is not EXCELLENT at the moment, I'll grant you that---but the method to get there (to excellence) is known and is devoid of roadblocks. It's just a question of time and resources, and it's in process because there's a lot of time and resources being devoted to it.

Why should I google it? you're the one making the claim, prove it.

Are you blind? Youíre the one who butted in with claims, written with all the credibility of a Best Buy salesman. Donít be lazy - do some research.

^ A great man once said that extraordinary claims require extraordinary evidence.

Playing devil's advocate, what's to say you didn't misunderstand or misinterpret the examples you claim exist and would thus be sending adtlogin on a wild goose chase? Your preface of not being an engineer is surely an admission that you don't intimately understand the way the upscaling works so how can you claim to know the extent of its capabilities? You just cite the AI buzzword and say it's "cool" then use rhetoric of time and resource being dedicated to upscaling (history has shown many times that doesn't guarantee a practical result e.g. the Space Shuttle) but you haven't given any explanation how you make more from much less with such a big gap in resolutions such as the 360p to 4K example given. By providing the links to the stories you said you like to keep up on, we'd be on the same page assuming you're correct.

I could claim I wrote a codec that can make a 2 hour 4K blu-ray video fit on a 1GB flash drive and decompress with pin-sharp clarify. Should I not be expected to prove that or does the burden of proof lie with the doubter?

Fair point. Maybe I undersold myself. I do know thing or two about technology, I'm just not an engineer (or a tech bro). I'll also add that the original poster mentioned Enhancenet, so in my dialog with him I took it for granted that we were on a similar page.

I'll explain AI upscaling and then provide a couple of links below. A lot of the explanations I found online were convoluted. The "AI" really refers to "machine learning", whereby a computer detects minute patterns in the data it's given. In this case, the machine is given 1000s upon 1000s of high-res images. This is a porn site, so let's use tits as an example.

The machine observes tits of all shapes and sizes, from different angles, and on a variety of women...different ages, proportions, you get the idea. It could tell you the arrangement of pixels on someone's left nipple. Then you take all those 1000s upon 1000s of images and you downscale them to tube TV quality. The computer will now map those low-res images to the high-res ones. Boom, done. Now when you feed the computer a brand new low-res image, it'll say, hey---those tits looks a lot like the ones on that 25 year old Hungarian beauty. I'll use that data to fill in the missing pixels and turn this one into a high-res image. That's all there is to it. I'm simplifying, but you get that. What the computer is analyzing is a lot more abstract than tits. In any case, the results are amazingly good.

There are hurdles. The first hurdle is video. The computer can upscale every frame of a video, but the problem is that it's going to upscale each frame slightly differently, like each frame is a fresh picture. There are ways to solve for that, but video introduces a new dimension. You want to upscale the image, but you also want to adjust it so that it appropriately matches the previous frame. All of this is done. It's already here, it's already technology. There are lots of pictures to give to the computer to analyze. The computers that do this work are expensive (but getting cheaper and better each year), plus you need the programmers and hardware engineers. But there's also lots of money to be made in upscaling low-res videos. You've got the archiving and history people, the survelliance and security people, the entertainment biz, and also TV manufacturers. The latest 8K TVs already do this upscaling in a more rudimentary way. 360p upscaling for everyone isn't 20 years away, it's more like less than 10...and potentially way less than that if you're into the latest gadgets and have money to blow.

^ The enhancement on what appears to be stills is pretty impressive with so many pixels missing though I'd like to see that done in real time on video at 60fps for example.

It's not that off topic, actually a very good point.
I know that Nvidia has recently used AI exactly for that (or better, for slow motion videos, but I think it's pretty much the same) with excellent results. It could be possible to have even a much higher frame rate than 60 fps.
