I'm wondering if AI can already solve this. I'm not even some crazy AI fanboy, I'm just thinking about the possibility of predictive AI being able to interpret compression artifacts to determine what forms would collapse into a particular pattern.

It's physically impossible to perform any type of analysis on a low resolution video and end up with a massively* upscaled and accurate result no matter what sort of technology you use. AI just guesses from what it can see and what it's been trained on. It's the digital equivalent of hiring an artist to create a higher quality rendition of a picture.

*There are some tricks that can be used to "enhance" images and especially videos, but not so much that it's like having optical zoom. For example, a bunch of noisy video frames of the same thing can be combined to get a less noisy result.

No, but AI can be used to make up "evidence" and falsely convict people through "science", "technology", and "math" that people don't understand but assume is correct because computers or something.

Have AI upscaled images been allowed as courtroom evidence?

There have been upscaling AIs for a few years, which can take a blurry picture and then e.g. guess that some pixels are probably hair, so it'll swap those out for a custom rendered version of hair.

Sometimes that works well, but you often still have Uncanny Valley stuff going on. I also certainly don't feel like they're better at actually interpreting low-res images than humans, not in their current state.

And well, it should also be noted that if you prime such an AI with an image of the suspect, it will absolutely find a way to make a blurry mess of pixels look like that. So, it certainly shouldn't serve as the only evidence.

Calm down there, you’re starting to sound all inquisitive & such. Like that creamsicle lookin’ fella from the show.

This already happens. See the Samsung S23 Ultra Moon picture marketing that turned out to be a lie.

There has been for some time AI image and video resolution upscaling for some time, and it works very very well. Allows zoom and "enhance" but not to the ridiculous scale we see here of course. But you can take standard CCTV footage and 4k upscale it and zoom. Its very impressive.
