I said it in the other thread, I'll say it here too:
If you look at the top right corner and then the "CONFIDENTIAL" watermark, you can see the direction of the text and the angle of the frame of the—supposed—video are not aligned; it's a very common AI error—a very typical, tiny detail of the picture that contradicts the rules of reality (like how part of what you see changes its form when you change the perspective). Those little nuances are what you can pick up on to realize it's AI.
