Parameters

|---|---|---|---|---|
promptRequired | string | — | — | Describe the subject, action, camera, light, pacing, and boundaries for the shot. |
aspect_ratioOptional | string | 16:9 | 16:9, 9:16, 1:1, 4:3, 3:4, adaptive | Output aspect ratio; adaptive follows the input media and the intent. |
enable_thinkingOptional | boolean | false | — | Let the model reason about the brief and the reference material before generating. Helps with complex references; slower. Switches on by itself when a reference file or link is given. |
resolutionOptional | string | 720p | 480p, 720p, 1080p | Output resolution. |
duration_secondsOptional | integer | 5 | -1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, … (+16) | Requested output length in seconds. Pass -1 for smart duration: the model picks the length from the prompt and any input media instead of a fixed number. |
generate_audioOptional | boolean | true | — | Request generated audio with the video. |
enable_prompt_expansionOptional | boolean | false | — | Allow the service to expand the submitted creative brief before generation. |
seedOptional | integer | — | 0 to 2147483647 | Random seed. Keep it fixed only for controlled comparisons, not as a frame-identical guarantee. |
