Ask HN: Who would be interested in a browser extension for fast video upscaling?

Just asking, I didn't develop anything yet.

It would allows you to turn a 360p video into a 4k video on the fly for example. It would fill also the black bars in vertical content or if you have a wide display. (Probably with something like stable diffusion)

Do you have any recommendations?

What would be the ideal ux and do you guys have any idea whether this is even possible with current technology?

What amount would you be ready to pay if any?
