Maybe it's time to beat the public over the head with PGP?
The only way to guarantee a given video isn't doctored would be to have it cryptographically signed by the camera that shot it. Of course, this would make even re-encoding impossible(so video-hosting sites would need to post (only?) the original or risk being called out), but that seems like a relatively small price to pay to be sure if that Pelosi-Schumer sex tape is real.
