Wouldn’t a code signing be a simpler way to achieve that? The video camera can produce a hash code with each video and you can always run the same hash function against the video file to confirm that it wasn’t tampered with.
I guess the problem NFTs try to solve is authority holding the initial verification tied to the video. If it’s on a blockchain, theoretically no one owns it and the date/metadata is etched in stone, whereas otherwise some entity has to publish the initial hash.
In other words, one can hash a video, yeah, but how do you know when that hashed video was taken? From where? There has to be some kind of hard-to-dispute initial record (and even then that only works in contexts where the videos earliest date is the proof, so to speak, like recording and event as it happens).
