Data schema
Input
| Field | Type | Description |
|---|---|---|
| codec | stringenum: auto, H264, H265 | 'auto' retains default video codec behaviour; 'H264' uses H.264; 'H265' uses H.265. |
| draft | boolean | Generate a draft preview at 480p, overriding resolution. Returns a draft_id for completing the draft at 1080p within 7 days. |
| promptrequired | string | The text prompt used to generate the video |
| duration | stringenum: auto, 4, 5, 6, 7, 8… | Duration of the video in seconds. Supports 4 to 30 seconds, or auto to let the model decide based on the prompt. |
| resolution | stringenum: 480p, 720p, 1080p | Video resolution - 480p for faster generation, 720p for balance, 1080p for high quality. |
| end_user_id | — | The unique user ID of the end user. |
| aspect_ratio | stringenum: auto, 21:9, 16:9, 4:3, 1:1, 3:4… | The aspect ratio of the generated video. Use 16:9 for landscape, 9:16 for portrait/vertical, 1:1 for square, 21:9 for ultrawide cinematic, or auto to let the model decide. |
| bitrate_mode | stringenum: standard, high | Output bitrate mode. 'high' requests a higher-quality, larger-file encode from the model; 'standard' uses the default bitrate. |
| generate_audio | boolean | Whether to generate synchronized audio for the video, including sound effects, ambient sounds, and lip-synced speech. The cost of video generation is the same regardless of whether audio is generated or not. |
Output
| Field | Type | Description |
