One useful distinction here is replacing a location versus planning around one. Would a 20–30 second stress test—with two actors, hands and props, and a small camera move—be enough to compare a real location, green screen/3D, and AI enhancement? For those who’ve tried it, what fails first: eyelines, lighting continuity, temporal consistency, or turnaround time? I’m trying to identify the test that shows whether AI saves money or merely moves the cost into post.
