Three useful first-run tests

Use the prompts below to test the failure modes that matter before committing to a larger batch.
Camera motion
“A camera pushes through a misty greenhouse toward a red flower as morning light breaks through the glass.”
Check the camera path, depth, and consistency of the flower.
Starting image
“Begin with the supplied portrait; the subject turns toward the window while the camera slowly pulls back.”
Compare the subject's face and clothing throughout the movement.
Action continuity
“A chef tosses vegetables in a pan, plates the food, and sets the plate on a wooden counter in one shot.”
Check hands, objects, and timing across the full action.
These prompts are evaluation recipes, not controlled benchmark results. Run the same prompt and settings across models before drawing a conclusion.
