This is really amazing.
The interesting shift here is from “AI makes video” to “AI helps direct and edit video”—more control, more repeatability, and a faster loop for filmmakers.
A concrete example of that “control” direction is Luma’s Ray3 Modify approach: start from real footage (or a base clip), then use AI to change wardrobe/lighting/backgrounds/effects while trying to preserve performance and motion—aimed at director-grade iteration.
