> keep objects consistent

I think this is not nearly as important as most people think it is.

In hollywood movies, everyone already knows about "continuity errors" - like when the water level of a glass goes up over time due to shots being spliced together. Sometimes shots with continuity errors are explicitly chosen by the editor because it had the most emotional resonance for the scene.

These types of things rarely affect our human subjective enjoyment of a video.

In terms of physics errors - current human CGI has physics errors. People just accept it and move on.

We know that superman can't lift an airplane because all of that weight on a single point of the fuselage doesn't hold, but like whatever.

Water level in a glass changing between shots is one thing, the protagonist’s face and clothes changing is another.

Location consistency is important. Even something as simple and subtle as breaking the 180-rule [1] feels super uncanny to most audiences. Let alone changing the set the actor occupies, their wardrobe, props, etc.

There are lots of tools being built to address this, but they're still immature.

ComfyUI has a lot of tools for this, they're just hard to use for most people.

Well put. Honestly the actor part is mostly solved by now, the tricky part is depicting any kind of believable, persistent space across different shots. Based off of amateur outputs from places like https://www.reddit.com/r/aivideo/, at least!

This release is clearly capable of generating mind-blowingly realistic short clips, but I don't see any evidence that longer, multi-shot videos can be automated yet. With a professional's time and existing editing techniques, however...

It all depends on quantity and "quality" of the continuity errors. There's even a job for it https://en.wikipedia.org/wiki/Script_supervisor

People got used to James Bond actors changing between movies, but from scene to scene in the same movie would be a bit confusing.

I wonder if this stuff is trained on enough Hallmark movies that even AI actors will buy a hot coffee at a cafe and then proceed to flail the empty cup around like the humans do. Really takes me out of the scene every time - they can't even put water in the cup!?

No way man, this is why i loved Mr Robot, they actually payed a real expert and worked story around realism and not just made up gobbleygook that shuts my brain off entirely to its nonsense
