Luckily the cup is quite a tell this time around.

I wouldnt have called it, but its all oddly stable. The ship should be rocking around in all directions even before the big wave. Ships also bend considerably but everything just stays perfectly still relative to the camera. Also where is the wind coming from that is blowing the papers? Paper doesnt just do that. Also the cup makes no sense. Also the sound is completely nonsensical. Fluttering paper shouldnt even be audible at all in this situation. It would be drowned out completely by the insane amount of noise from everything going on. Also all that water rushing in should make everything darker not brighter unless the insanely bright floodlight is literally right next to this window.

My guess is that the interior and the exterior are two separate scenes edited together. The exterior AI generated, the interior maybe not or maybe as well.

Another circumstantial piece of evidence is that its impossible to find videos like this (perfectly stable camera, high res, etc) from any time before AI generated videos were a thing. Its a very popular category of slop because ever since ~2 years ago there are hundreds of these videos.

For comparison a slightly older video with a bunch of ships colliding with much smaller waves: https://www.youtube.com/watch?v=AduB4Yp9n0s

Look at all the movement despite a comparably calm ocean.
