Data schema
Input

|---|---|---|
| seed | — | Random seed. A random seed is selected when omitted. |
| lorasrequired | array | List of LoRA adapters to apply to the transformer. |
| promptrequired | string | Text prompt for video generation |
| duration | integer | The duration of the video in seconds. |
| sync_mode | boolean | Return the generated video as base64 instead of a CDN URL. |
| resolution | stringenum: 480P, 768P, 2K, 4K | The resolution of the generated video. 480P and 768P are native generation modes; 2K and 4K upscale a 768P base result. |
| aspect_ratio | stringenum: 21:9, 16:9, 4:3, 1:1, 3:4, 9:16 | The aspect ratio of the generated video. |
| target_audio_url | — | Optional URL of an audio clip at least 2 seconds long (maximum 15 MB) to pin to the generated soundtrack. Longer clips are trimmed to the requested video duration, keeping the beginning. The original audio replaces the output soundtrack, padded with silence if shorter than the video, without changin… |
| enable_safety_checker | boolean | If set to true, the safety checker will be enabled. |
| prompt_expansion_mode | — | How much effort to spend rewriting the prompt before generation. 'disabled' skips prompt expansion. 'fast' returns in about a second. 'balanced' picks per request. 'quality' spends up to ~30s on a richer prompt. |
Output
| Field | Type | Description |
|---|---|---|
| video | — | The generated video |
| expanded_prompt | — | The prompt after expansion, as sent to the model. Null when prompt expansion was disabled, left the prompt unchanged, or was performed internally by MiniMax's hosted API. |
