I think you might have misunderstood some core use cases.
One significant problem currently is long form discussions which are taken wildly out of context for the sake of propaganda, cancelling or otherwise damaging the reputation of those involved. The point isn't that a given video isn't edited originally, but that the original source video can be compared to another (whether the original was edited or not is neither here nor there).
I'm not saying this solution is the answer, but attempts to be able to prove videos were unedited from their original release is a pretty reasonable goal.
I also don't follow where the idea that viewers need to be forensic experts arises from? My understanding is that a video can be verified as authentic, at least in the sense of the way the original author intended. I didn't read that users would be responsible for this, but rather that it can be done when required.
This is particularly useful in cases like the one I highlighted above; where a video may be re-cut to make an argument the person (or people) in question never made (and which might be used to smear said persons–a common occurrence in the world of long form podcasting as an example).
It would be interesting to know if you could write software to take a video with these flashes in it, post-process them out, morph the video to be taken from another angle, add in a different signature. Then claim the first video is fake and that the 2nd video is the true unedited version.

It would be pretty cool to live in that word, where a maliciously edited video can be met with a better verified, full version of it.
I don’t think that’s where we are, right? People are happy to stop looking after they see the video that confirms their negative suspicions about the public figure on the other team, and just assume any negative clips from their own team are taken out of context.
While I don't know if the paper is "stupid", or not, I think nobody in the last two decades has ever seen an uncut interview. So I don't see how this light would help or proof anything.
I think it is a current propaganda or messaging strategy: you say “In the uncut recording of the interview, I made really good points, but they spliced it up to make me look stupid,” or “In the uncut version of the interview, my opponent said a bunch of nonsense, but they cut it out.” This works because the broadcaster isn’t going to play the uncut version, and even if they did, nobody would bother watching it.
The broadcaster doesn't need to run the unedited video--anyone can keep a copy. Somebody edits the wrong answer onto a question, produce your unedited recording and point out what they did. (And, in a perfect world, sue for defamation.)
