If this becomes a problem, I think cameras and smartphones would be upgraded with a way to certify they are real videos. I have no idea how, and it would likely have to keep evolving, but if the financial incentives are there I'm sure someone will figure it out. Maybe the video gets signed by the phone and can only be verified by that device?

Flash the flashlight in a sequence corresponding to the most recent hash on the bitcoin blockchain, then take a hash of the video and send 0.00000001 BTC to that address from a wallet associated with your personal identity? Would pretty much prove that a specific person recorded this video between two fairly close together times, and the blinking lights would probably do things with shadows that deepfakes aren't great at replicating (and retouching the video to fix those artifacts would make the hash not match).
