Settings and model questionsCheck the available settings and guidance when preparing your input.
Inputs and settings
For text or image generation, use prompt or multi_prompt, not both. Choose 3–15 seconds; generate_audio controls generated sound. Image mode requires image_url.
Reference and Edit modes support elements: add a frontal image and 1 or 3 extra views per image element (2 extra views are not accepted), then use @Element1 in the prompt. image_urls are separate references, named @Image1.
Edit requires video_url and prompt. keep_audio controls source sound. A video input permits at most four elements and separate reference images combined; the extra views inside an element stay grouped with it.

From quote to result.
Request a credit quote for your input and settings before submitting a generation. A sample output or the price of another model is not a quote for your request.
Follow the generation workflow, then poll the job for its status and result. The API and studio use the same balance.
