Oh but they have sound which can be annotated much faster/more efficiently. You also potentially have screenplay but the amount of training data is probably too less and sparse. FWIW, I don’t think the AI systems will generate a whole video by itself - it’ll be some form of image to image generation where an artist will render a rough sketch of the scene and the AI will fill in the details, frame by frame.
