Describe four concrete details.
A useful prompt names the subject, action, camera and visual style. Give the scene one main action so the model has a clear movement to follow.
An adult heroine in navy armor steps into the light. Her short silver hair moves in the wind. A slow camera push frames her face. Cool stadium lighting, natural fabric movement and a restrained cinematic look.
Let your references do their job.
In Image to Video, your image provides the first frame. Describe the movement you want after that frame. In Video to Video, the reference can guide timing or motion. Say what should change without asking for an unrelated action at the same time.
Refine one issue at a time.
If the camera moves too much, change the camera direction. If the identity drifts, improve the subject reference. Keep the other settings steady so you can see what each change does.
Review the quote for each take.
Different models, durations and qualities can use different credit amounts. Each take is a separate request. Use the quote shown before generation to decide whether the settings fit your balance.
