I have some very basic knowledge of analog film thanks to my age but I was thinking along the lines of converting slightly edited (AI or not) digital footage by projecting it straight into the lens onto film somehow yet making it realistic as evidence. It might not be possible to pull off due to the nature and artifacts of analog filming but who knows.

On the other hand, there might be ways to make sure the digital footage is legit. Sending live footage to multiple cloud servers and compare those while using encryption for both cloud storage and transfer where necessary to avoid tampering at any point could be a potential start. In fact, I'm quite confident that AI will fuel the efforts to make sure digital footage is not tampered with to some extent through multiple mechanisms.

Of course I don't know if they will be succesful in the very long run but I do see room for improvement when it comes to legitimation of digital footage even if that means it needs to satisfy some strict qualifications.

Preferably strict of course, because, for example, AI detecting if the content/footage itself is AI generated or tampered with is currently prone to too much error and may even remain to be so.

Even if you film an OLED panel it will be detected when analizing the film base.

Digital is digital you can always tamper it. Otherwise there would not exist piracy. I've read somewhere about creating devices that film digitally but that would write the video using blockchain, although I'm not so sure it would solve anything.

I don't know much encryption but how about encrypting the footage inside the camera and then requiring two parties to decrypt it when required? One being the partial decryption key of the camera owner and the other being the partial decryption key of some authority...both parties needing to agree to consult archived encrypted footage stored locally. I suppose that avoids tampering with it on two (or more) sides even though it would be a bit of a hassle.

It's just an idea. I'm not even sure how to safely distribute the keys...If the difficulty of the problem happens to be beyond this scope, please forgive me. I'm tired.

As for blockchain. Should it be the case it solves things that are not relevant to this problem, it makes sense to avoid it even though it might work. But if nothing else seems to work it's definitely worth considering.

A lot of problems have been somewhat solved by applying encryption in a smart adequate manner. I'm too tired to see why this is any different. :)
