A big chunk of the right side of castle disappeared, including catapult, when camera turned back while flying on dragon. See 1:25 to 1:29. I was not expecting this to happen in a "world model".

The 80's Japanese train station clip also had the conductor speaking clear english in an accent I can't quite place. Slight British tinge to it but not really? Not sure. The ambient audio also makes no sense.

I've seen weird stuff in images that OpenAI sends me in it's promotional emails too. I would think that if you were trying to show off you'd make sure there's none of these obvious AI issues in what you choose to show off with. Maybe they don't really care? "Gemini choose 10 scenes that would be impressive for our announcement and add them to the post."

That entire clip looks like it's straight out of a complete bargain-bin videogame. The weird smoothness of the ride, the pivot in mid air, the wings apparently don't have collision with the poles they fly past.

Definitely wouldn't have been one of my picks to show off my fancy new model.

There's also a whole extra bonus castle that appears to the left when the camera looks left around 0:22. Which is amusing both because it wasn't there on the initial approach, and also because nobody puts two castles each with their own distinct curtain walls right next to each other like that.

The oddest thing about this, to me at least, is that they pick that as their showcase. Did they themselves not notice? Or did they think their potential customers wouldn’t? Not sure really which of the two is worse.

In the original dragon clip, at 0:29 we can see a square tower in the right side of the screen

As he passes by the tower, it becomes round, by 0:40

It is always incredible to me how quickly we go from "this entire technology is pure science fiction" to "nitpicking over details"

I was under the impression he has already fly past the catapult.
