Unless something radically changes, we're quite far from creating movies on demand. Most AI video generators cost ~$1-10 per minute. And generally it takes many attempts to generate a few seconds of anything that's not completely trash.

Another issue is quality. Most of these AI generators output quite blurry 720p. If you want proper 4K output, we're at least a couple of doublings away.

I think we will have some decent AI-generated animations next year, because 2D cartoons are relatively easy to upscale.
