No I think we’re actually close. My source is I’m working on this problem and the incredible progress of our tiny 3 person team at drip.art (http://api.drip.art) - we can generate a lot of frames that are consistent, and with interpolation between them, smoothly restyle even long videos. Cross-frame attention works for most cases, it just needs to be scaled up.

And that’s just for diffusion focused approaches like ours. There are probably other techniques from the token flow or nerf family of approaches close to breakout levels of quality, tons of talented researchers working on that too.
