I think we rescued a point where AI videos have Uncanny Valley status, and because of that, any unusual thing, or less than great quality in a real video will make us doubt its authenticity. A person who is unaware of generative AI (but aware of CGI in general) will probably not think this is fake.

I’m inclined to think this is real. It bears no signs of the Hallmark tells of an AI video. Everything looks very solid and non-deforming.
