You’d need to be more specific. If you’re talking about taking CD quality audio and Up-sampling to “high res” audio, what you’re actually doing is fabricating new inaudible frequencies which do nothing except potentially degrade the audible sound if your tweeters aren’t up to the task of reproducing these useless frequencies perfectly.
What I am excited for is a narrowband to wideband algorithm which can turn a Ye Olde Microphone recording or possibly even a telephone conversation into something resembling a modern recording. Obviously there’s only so much you can do with a recording made on a terrible microphone, but it should be possible to make historical recordings clearer.
My personal favourite is Remacri for photographs, but you should download a few of them and try what works best for the photo/image you have.
You can use either Automatic1111's repo for stable diffusion to try them out (put the model file in the ESRGAN directory), or also chaiNNer (https://github.com/chaiNNer-org/chaiNNer)

Wonder what the comparison is…
I suspect they are just not really wanting to advertise such a slow user experience, which is reasonable.

And other implementations thereof, e.g:

I'm getting poor results trying with some stamps I've scanned and some photos that were lower resolution than I liked.
Or does it need to be studio quality footage?
Nothing I've tried is. I might try this one out to see, but if anyone who has can comment on how it compares, I'd appreciate it.
My use case is 2x upscaling detailed, very small pixel-art-style images, like icons and retro game assets.
