I have a friend who was working on #1 specifically. They got out of it after they realized it was just playing whack-a-mole. This is honestly one of the very few use cases of cryptography signing a video or picture that I can see. But that would mean amateur journalists or the common person might be excluded from being a trusted source with video evidence.

Why? If my iphone camera signs every 24th frame (seems a conservative estimate of speed to do hash and sign), using a combination of the apple camera CA public key and my private key in the secure enclave than we can be reasonably sure that the raw footage now on my site came from a genuine iphone and from the phone I registered (somewhere) All we are doing is trusting that the video images came from a given piece of hardware that we can trust belongs to me. Whether I can be trusted is the same age old problem we have always had But this simply makes it exponentially harder to fake or alter digitally any image (or at least look stupid when someone says "Citation Needed") - if you cannot produce the original raw footage questions will be asked why. I can imagine this being something wanted on police bodycams quite soon
