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).

This is such a funny thing to say since NFTs were all about “owning” stuff on the blockchain.
Those would probably be a part of it.
Comparing a hashcode implies you have a verifiable source for the original footage.
You can do this manually and dig for the author but thats not always that simple.
A second step would be to build In a reference to the record in each media file, expressed as a small clickable logo.
You grandma deserves to be capable to verify.
