Plan your shot
Describe the subject, setting, light, action and camera in a single shot. Choose 5 or 10 seconds and landscape or portrait framing. Review the estimate, generate the clip and inspect the movement before refining the prompt.
A useful starting point
Make the camera instruction concrete: a slow dolly toward the subject or a steady sideways tracking shot is easier to assess than a vague request for something cinematic. Avoid competing camera moves within the same short clip.
Example prompt
A cyclist crosses a quiet coastal road at golden hour. A steady side tracking shot, warm light on the bicycle frame, gentle sea breeze and a clear horizon. One continuous shot with natural motion.
Credit cost examples
