OK, let's see it make full-sized videos first; making tiny demo videos is a long way from showing it at 4K. Also, let's see the entire paper and note how many computing resources were required to build the models. Until everyone can try it for themselves, we have no idea how cherry-picked the examples were.
TV ads are short. 20 seconds of HD could be enough, easily upscaled to 4K.
I think it might be within the realm of the possible to see 30 second videos at the end of the year.
The next step could then be infinitely long videos when frames are getting generated at 24 fps, as long as the ability is given that they are able to stick to a story and a visual style that makes sense. The story could evolve automatically from an LLM or be generated in real time by an artist, like a prompt every minute. In any case, we're not that far away from this, even if the first results will be more like trippy videos.
