Data schema
Input
| Field | Type | Description |
|---|---|---|
| seed | — | Random seed for reproducibility. If None, a random seed is chosen. |
| lorasrequired | array | Up to 3 LoRAs to apply on top of LTX-2.3. Each path is downloaded through the registry SSRF-safe downloader before it is loaded. Max size: 3 GB per LoRA. |
| promptrequired | string | The prompt to guide the audio-driven video generation. |
| audio_urlrequired | string | The URL of the audio track that drives generation. |
| image_url | — | Optional URL of an image to use as the first frame. When omitted, generation runs from text and audio only. |
| sync_mode | boolean | If True, the media is returned as a data URI inline in the response. Useful for short-lived requests and tests. |
| num_frames | integer | The number of frames to generate. |
| resolution | — | Final output size. 'auto' matches the input image aspect ratio when image_url is provided; otherwise it uses a landscape fallback. |
| video_quality | stringenum: low, medium, high, maximum | The quality preset of the generated video. |
| generate_audio | boolean | Whether to include audio in the returned video. When disabled, the final MP4 is returned without an audio track. |
| guidance_scale | number | Classifier-free guidance scale. The default is tuned for fast, high-quality generation. |
| image_strength | number | Conditioning strength for the optional first frame. 1.0 keeps the image more strictly; lower values give the model more freedom. |
| negative_prompt | string | The negative prompt to steer generation away from. |
| video_write_mode | stringenum: fast, balanced, small | The write mode of the generated video. |
| frames_per_second | number | Frames per second of the generated video. |
| match_audio_length | boolean | When enabled, derives the number of frames from the audio duration and frames_per_second. When disabled, uses num_frames. |
| num_inference_steps | integer | Number of inference steps. Defaults to 15 and can be increased up to 30. |
| enable_safety_checker | boolean | Whether to enable the safety checker. |
| enable_prompt_expansion | boolean | Whether to enable prompt expansion. |
Output
| Field | Type | Description |
|---|---|---|
| seed | integer | The seed actually used for generation. |
| video | — | The generated video. |
| prompt | string | The prompt used for generation (after any expansion). |
