Request Body

application/json

These parameters come from the selected model form_schema. Switching models updates this list and the request example.

prompt*string

Describe the video scene, action, and art style you want to generate. Supports Chinese and English. Up to 2500 Chinese characters or 5000 non-Chinese characters.

RequiredExample Value: A cinematic, extreme close-up video of a giant, ornate hourglass standing on a mahogany table. Inside, instead of sand, flowing liquid gold mixed with glowing sapphire dust falls through the narrow neck. As the liquid hits the bottom, it splashes in slow motion, creating crown-shaped ripples that freeze into intricate crystalline structures. The glass of the hourglass is etched with moving astrological symbols that glow with a soft white light. Outside the glass, wisps of thick, purple incense smoke curl and drift lazily around the frame. The lighting is warm and flickering, as if from a nearby fireplace, creating deep amber highlights and long, dancing shadows. 4k, 60fps, shallow depth of field with heavy bokeh, focus on the fluid dynamics of the falling gold and the texture of the carved wood.Placeholder: Example: A cute panda in a spacesuit floating in space, with a colorful nebula in the background...
