Parametri
| Campo | Tipo | Predefinito | Valori ammessi | A cosa serve |
|---|---|---|---|---|
promptObbligatorio | string | — | — | Describe the intended subject, action, camera, light, sound, and constraints. |
aspect_ratioFacoltativo | string | adaptive | 16:9, 9:16, 4:3, 3:4, 1:1, 21:9, adaptive | Output frame ratio. |
resolutionFacoltativo | string | 720p | 480p, 720p | Output resolution. |
duration_secondsFacoltativo | integer | 5 | -1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 | Requested output duration in seconds. Pass -1 for smart duration: the model picks the length itself instead of a fixed number. |
generate_audioFacoltativo | boolean | true | — | Request synchronised output audio. |
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. |

Parametri
| Campo | Tipo | Predefinito | Valori ammessi | A cosa serve |
|---|---|---|---|---|
video_urlObbligatorio | string (uri) | — | — | The clip to continue: MP4, MOV or WebM, up to 60 seconds. Its last frame opens the new segment, and the result is your clip with the new segment joined on. |
promptFacoltativo | string | — | — | What happens next: the action that follows, the camera move and the sound. Optional. |
last_image_urlFacoltativo | string | — | — | Optional closing image: the new segment lands on this picture. Leave it out and the model decides how the shot ends. |
resolutionFacoltativo | string | 720p | 480p, 720p | Resolution of the new segment. Match your source clip. |
duration_secondsFacoltativo | integer | 5 | -1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 | Length of the new segment in seconds. This is the billed quantity; the source clip is added on top and is not billed. Pass -1 for smart duration: the model picks the length itself. |
generate_audioFacoltativo | boolean | true | — | Generate a native soundtrack for the new segment. The source keeps its own sound either way. |
seedFacoltativo | integer | — | da 0 a 2147483647 | Random seed. Omit to let the model pick one. |
bitrate_modeFacoltativo | string | standard | standard, high | Encoding bitrate of the delivered file: standard, or high for crisper detail and a larger file. |
