This still fundamentally suffers from the oracle problem like all blockchains solutions. You can always attack these blockchain solutions at the point where they need to interact with the real world. In this case the camera is the “oracle” and nothing prevents someone from attacking the proposed camera and leveraging it to certify some modified footage. The blockchain doesn’t add anything a public database and digitally signed footage wouldn’t also achieve.
This is a flaw i had considered and never found a solution for. Hence the idea is unfinished.
The only further argument i have is that manipulating camera techniques is as old as film yet it’s the digital tools that are causing the most harm and allow any troll to partake. Staging a scene takes at least some dedication and effort.
If such would be considered on the blockchain than it would also bring in questions all other footage by the same recorder device. “Wallets” from established authors, anonymous or not would have their own reputations of trustworthyness.

There are decentralized oracles. That’s how DAI tracks the price of USD.
