Inputs (9)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | What happens next: the action that follows, the camera move and the sound. Optional. | |
| video_url | VIDEO | 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. | |
| resolution | COMBO | 720p | Resolution of the new segment. Match your source clip. |
| duration_seconds | COMBO | 5 | 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_audio | BOOLEAN | true | Generate a native soundtrack for the new segment. The source keeps its own sound either way. |
| seed | INT | 00–2147483647 | Same seed and settings, same result. Set 'control after generate' to randomize to get a new result on every run; every run is billed. |
| bitrate_mode | COMBO | standard | Encoding bitrate of the delivered file: standard, or high for crisper detail and a larger file. |
| watermark | BOOLEAN | false | Add the model’s visible "AI generated" watermark to the video. |
| last_image_urlopt | IMAGE | Optional closing image: the new segment lands on this picture. Leave it out and the model decides how the shot ends. |
