I want the whole human story in one shot — from the first people to the AI we use now. 15 seconds, 16:9, no narration, no on-screen text until the very last frame. One continuous move, never cutting. The camera pushes forward and the world changes around it: firelight on a cave wall, a hand pressed in ochre, then fields and the first walls, then a printing press, then steel and smoke, then a wall of city light, then a room of humming machines, then the light of a screen on a face in the dark. Each era arrives while the last one is still leaving — the fire becomes a furnace, the cave painting becomes a page, the page becomes a screen. Hand things off on shape: something round stays round, something bright stays in the same corner of the frame. Keep a human in almost every era, always small in the frame, so the scale of the thing reads against a person. No famous faces, no logos, no company names, no invented alphabets on signage. It should feel like one long exhale, not a slideshow. The last frame can carry one line of English text, my choice later — leave it clean. Give me the finished mp4, a cover frame, and the prompts you used per shot.
