Prompting
Prompt tips
Describe the subject, setting, action, camera movement, and desired audio in your prompt. For a sequence of actions, write clear beats in the order they should occur.
Give each reference a clear purpose, such as character appearance, composition, or movement. Use start and end frames when you want to guide the opening and closing images.
Start with a short clip, review the output, and adjust one part of the prompt or reference set at a time.
