The tech is going to have to be absolutely flawless, otherwise the uncanny-valley nature of AI "actors" in a movie will be as annoying as when the audio and video aren't perfectly synced in a stream. At least that's how I see it..
For most of them I'm not seeing any of those issues.
A couple years ago, we thought the trend was without limits - a five second video would turn into a five minute video, and keep going from there. But now I wonder if perhaps there are built in limits to how far things can go without having a data center with a billion Nvidia cards and a dozen nuclear reactors serving them power.
Again, I don't know the limits, but we've seen in the last year some sudden walls pop up that change our sense of the trajectory down to something less "the future is just ten months away."
The quick cuts thing is a huge turnoff so if they have a 15 second clip later on, I missed it.
When I say "1second" I mean that's what I was doing with automatic1111 a couple years ago. And every video I've seen is the same 30-60 generated frames...
