One clean frame of the product on a transparent background: correct shape, correct label, correct proportions, nothing else in the picture. Every subsequent angle, set and motion clip references that file instead of a fresh prompt.
The plate is also the arbiter. When a frame is questioned, it is checked against the plate at forty per cent opacity. The previous frame and somebody’s memory are both inadmissible. That single discipline is what makes ninety frames of one product survivable.
QUESTIONS PEOPLE ASK
How do you keep a product looking identical across AI images?
Build a master plate first, generate everything from it, and run a silhouette overlay on every output. Any shift in outline kills the frame and it goes back to the plate.
