Very late so probably invisible to all, but is this just a byproduct of OpenAI's work on understanding of video input? The Google Gemini presentation video suggested that this is the next step-level of AIs. Already with GPT-4V, being able to converse with an AI about the contents of an image feels surreal. The applications that become possible with an AI that can just look at video streams are incredible.

I am a CG artist and Director and this made me so sad. I am watching in horror and amazement. I am not anti AI at all, but being on the wrong side of efficiency, for the individual this is heartbreaking. its so much fun to make CG and create shots and the reason its hard (just like anything) makes it rewarding.

I think it's worth remembering that all of these AI's work by having an unbelievably large number of weights. So many weights that it's all an uncontrollable black box. On the other hand, your work is all about having control, and I don't personally expect your work to lose value for this reason.

Another thing to think about is what the AI is designed to do. Without knowing the details, I would expect it to be trained to produce the 'most likely' output given the prompt. Consequently, I would think being inventive is against its design, and 'most likely' is effectively that same as 'average'.

This is amazing and was to be expected. Are there any good solutions that can be used to prove a video is not generated? I guess in some ways we have come full circle and are back to trusting individual journalists and content creators I just did'nt think it would happen this fast.

Has anyone else noticed the leg swap in Tokyo video at 0:14. I guess we are past uncanny, but I do wonder if these small artifacts will always be present in generated content. Also begs the question, if more and more children are introduced to media from young age and they are fed more and more with generated content, will they be able to feel "uncanniness" or become completely blunt to it. There's definitely interes…

Tangent to feeling numb to it - will it hinder children developing the understanding of physics, object permanence, etc. that our brains have?

Kids have been exposed to decades of 2D and 3D animations that do not contain realistic physics etc; I’m assuming they developed fine?

This is insane. But I'm impressed most of all by the quality of motion . I've quite simply never seen convincing computer-generated motion before . Just look at the way the wooly mammoths connect with the ground, and their lumbering mass feels real. Motion-capture works fine because that's real motion, but every time people try to animate humans and animals, even in big-budget CGI movies, it's always ultimately obvio…

> I've quite simply never seen convincing computer-generated motion before

I’m fairly sure you have seen it many times, it was just so convincing that you didn’t realize it was CGI. It’s a fundamentally biased way to sample it, as you won’t see examples of well executed stuff.

I say this with all sincerity, if you're not overwhelmingly impressed with Sora then you haven't been involved in the field of AI generated video recently. While we understand that we're on the exponential curve of AI progress, it's always hard to intuit just what that means. Sora represents a monumental leap forward, it's comically a 3000% improvement in 'coherent' video generation seconds. Coupled with a significan…

I think it's fair to be impressed with Sora as the next stage of AI video, yet not be too surprised or consider it some insurmountable leap from the public pieces we've seen of AI video up to this point. We've always been just a couple papers away, seeking a good consistency modelling step - now we've got it. Amazing and viscerally chilling - seeing the net effect - but let's not be intimidated so easily or prop these guys up as gods just for being a bit ahead of the obviously-accelerating curve. Anyone tracking this stuff had a very strong prediction of good AI video within a year - two max. This was a context size increase and overall impressive quality pass reaching a new milestone, but the bones were there.
