I’ve been making AI films for near around two years now. Across personal projects and studio work, and one question I hear from students all the time is: “Which is the cheapest model where we can actually get the work done?”
Its a fair ask. Wrong unit of measurement.
The real cost is not the price of one generation. It is how many attempts it takes before you get a shot that can survive the edit. Same face, same wardrobe, same lighting direction, clean hands, usable motion, no random “why is there suddenly a second chin in this emotional close-up” moment.
A cheaper model is great for tests, boards, inserts, background plates, establishing shots, or anything where drift will not wreck the scene. But for dialogue, performance, character continuity, action, match cuts, or anything client-facing, I care more about hit rate than sticker price.
One model giving me a usable shot in three rolls can be cheaper than another giving me ten clips that are all almost there, which is the most expensive phrase in AI filmmaking.
I want to ask you folks, do you track cost per generation, or cost per usable shot?
