This would work for videos that people want to acknowledge as their own, but they could just tweet out they own it for the same affect.

The issue this tackles is videos that people don't want to claim ownership of, e.g. if a video emerged of <insert politician here> kicking a child, the politician can't say "I haven't signed it therefore it's not mine", instead we need tools like the above to be able to say, "this is faked, do not trust it".

Maybe in the interim we need deepfake detection tools, but I'm asking about the long run. Suppose signed AV takes off as described above. The public has been trained: "If the video doesn't have The King's Seal, it's not from The King."

I think the point is that yes, that seems like a good solution for verifying content that purports to be released by a certain creator, but it doesn't solve the problem of deep fakes for captured footage i.e. you can prove it isn't a video that you created, but you can't prove it isn't a video someone else took of you.
