The NFTs tried to solve this problem already and it didn’t work. You can change the hash/sig of a video file by just changing one pixel on one frame, meaning you just tricked the computer, not the people who use it.
so try again?
also: if a pixel changes then it isn’t the original source video, by definition. being able to determine that it has been altered is entirely the point.

By changing one pixel it’s no longer signed by the original author. What are you trying to say?
Exactly that, if I change a pixel then the cryptographic signature breaks
