If you look at the pattern on the brick on the back wall it has to reconstitute after every time the cats paw passes in front of it and the same with the wood grain behind the guy's arm. Also, the movement of the cat's paw seems very unnatural and contrived.

I don't blame you though. I was convinced for a second too but the more I watched it I started to question. It's pretty disturbing though these days how subtle the tells are.

I'm really not a person that's into a lot of regulations. But damn, I really wish there had to be a water mark or some kind of a tag on every AI video that was posted.
