Prompt playbook
Scan the quick playbook first. Open the full guide only when you need deeper do/don't rules or example prompts.
Start simple and iterate — begin with a straightforward prompt and add details progressively rather than front-loading complexity.
Focus on visual detail, not conversation — describe how elements should appear rather than asking to 'add' or 'remove' things.
Use general terms for subjects in image-to-video — refer to characters as 'the subject' or simple pronouns so the model focuses on motion rather than reinterpreting details.

Extra prompt tips, best practices, common mistakes, and example prompts.
“The subject slowly turns toward the camera, sunlight catching the edges of her hair. A gentle breeze moves the grass in the background. Camera: slow dolly-in, shallow depth of field.”
“A vintage sports car cruises along a coastal highway at sunset. Camera tracks alongside at matching speed. Waves crash against rocks below, palm trees sway in the wind. Warm golden light, cinematic wide shot.”
“Overhead shot of a calligrapher's hand writing flowing script on cream paper. Ink glistens as each stroke is drawn. Static camera, macro lens, shallow depth of field. Warm desk lamp lighting.”
