Doesnt that just mean you need to validate the source of the video? If LTT says to stay way from a product on the LTT main youtube channel - that would seem valid?

Going further, digital watermarking is the obvious solution to this problem. Signed hash of each frame attached to the video, signed by the authors private key. You can verify integrity and authenticity if you trust the key.

Key sharing is annoying but at least you have continuity in the same sense as normal “reputation” and Keybase showed us it’s possible to like PGP keys to social media accounts with decent usability.

How many videos can you validate in a day? When someone watches 37 TikTok remixes in a row, how are they going to stop and check which ones are legit and which ones are fake?
