There are plenty of timestamping services out there, both blockchain-based and otherwise. If a video creator timestamps their video as soon as they create, and before they upload it, it could prove definitively these kinds of fraudulent claims.
Also, these services are usually reasonably priced, and sometimes even free, so it would be reasonable to use even if you're making several videos a day.

The immediate issue I see here is timestamping other people’s videos who produced them in the past, or for a different service, or just plain old didn’t know they needed to timestamp their video to protect it.
If you're goal is only to prove that you invented something before some random patent troll did, then that issue doesn't matter so much.
At the least, it's very, very strong evidence for a trial. Along with also emailing your lawyer or notary public a copy of the timestamp as soon as you create it, these factors would be virtually unassailable in a court of law.
