Agreed, at first glance of the woman walking I was so focused on how well they were animating that the surreal scene went unnoticed. Once I'd stopped noticing the surreal scene, I started picking up on weird motion in the walk too.
Where I think this will get used a lot is in advertising. Short videos, lots going on, see it once and it's gone, no time to inspect. Lady laughing with salad pans to a beach scene, here's a product, buy and be as happy as salad lady.
My instagram feed is full of AI people, I can tell with pretty good accuracy when the image is "AI" or real, the lighting and just the framing and the scene itself, just something is off.
I think a similar thing will happen here, over the next few months we'll adapt to these videos and the problems will become very obvious.
When I first looked at the videos I was quite impressed, but I looked again and I saw a bunch of werid stuff going on. I think our brains are just wired to save energy, and accepting whatever we see on a video or an image as being good enough is pretty efficient / low risk thing.
