Parametri
| Campo | Tipo | Predefinito | Valori ammessi | A cosa serve |
|---|---|---|---|---|
promptObbligatorio | string | — | — | What to generate: subject, action, camera movement and mood. |
aspect_ratioFacoltativo | string | adaptive | 21:9, 16:9, 4:3, 1:1, 3:4, 9:16, adaptive | Aspect ratio of the generated video. |
resolutionFacoltativo | string | 720p | 480p, 720p, 1080p, 4k | Output resolution. Super-resolution tiers are not offered. |
duration_secondsFacoltativo | integer | 5 | -1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 | Clip length in seconds. This is the billed quantity. Pass -1 for smart duration: the model picks the length itself instead of a fixed number. |
generate_audioFacoltativo | boolean | true | — | Generate a native soundtrack synchronised to the picture. |
enable_web_searchFacoltativo | boolean | false | — | Let the model search the web for information related to the prompt before rendering. Requests with it on are billed at the web-search rate. |
seedFacoltativo | integer | — | da 0 a 2147483647 | Random seed. Omit to let the model pick one. |
return_last_frameFacoltativo | boolean | false | — | Also return the clip’s final frame as a separate image. |
bitrate_modeFacoltativo | string | standard | standard, high | Encoding bitrate of the delivered file: standard, or high for crisper detail and a larger file. |
watermarkFacoltativo | boolean | false | — | Add the model’s visible "AI generated" watermark to the video. |
