Yes, I am aware this model is just about a video without sounds and other elements, but even without those other elements it will be very useful. A lot of animations can be made out of this, for example, many YouTube animators might see this as gold.

When it says movies I don't think it necessarily means 90 minutes at once, I seriously doubt that it will generate a whole movie at once, it might be able to generate 5-15 min animations then you can add them up as you said (which will reduce the compute cost). The one prompt thing won't be a thing (yet) I believe, having to give it several prompts will make the animation more aligned with the users' desires. I don't necessarily agree that it is just a tool, many fun things can be done with this from the average person's perspective. But that's beside the point I'm more interested in what companies like Deepmind, Open AI, google, and others might release when it comes to movie generators this year.

>A very good multimodal AI that can create both the image and the sound, including music and voices, we are very far away from that. (Now, "Very far away" might be just 2 or 3 years, but certainly not this month)

LOL, I give it a year (1,5 years max). Remember we need to think exponentially, this is just the beginning of 2023 we are yet to be blown away by the products that will be released this year.
