Yeah, it's unfortunate that video compression already introduces artifacts into real videos, so minor genAI artifacts don't stand out.
It also took me a while to find any truly unambiguous signs of AI generation. For example, the reflection on the inside of the windows is wonky, but in real life warped glass can also produce weird reflections. I finally found a dark rectangle inside the door window, which at first stays fixed like a sign on the glass. However it then begins to move like part of the reflection, which really broke the illusion for me.
