"they should not, under any circumstances, use a video or image as proof or assume its veracity"
This is just silly. Courts never assume the validity of evidence. It is actually assumed to be invalid unless it can be proved to have not been tampered with. Photos have been able to be edited for over 100 years but they are still used as evidence. The person who took the photo will sign an affidavit and or testify in court that it is real. And AI videos are going to be easily detectable for a long time.
I'm talking about your average person, not the court system. I'm asserting that culturally we need to shift to acknowledging that photos are not proof, rather than pretending that some fancy counter-model or watermarking will somehow allow us to maintain an already-misplaced trust in the veracity of images.
