Data schema
Input
| Field | Type | Description |
|---|---|---|
| fps | number | The frames per second of the generated video. |
| seed | — | The seed for the random number generator. |
| promptrequired | string | The prompt to generate the video from. |
| sync_mode | boolean | If `True`, the media will be returned as a data URI and the output data won't be available in the request history. |
| video_urlrequired | string | The URL of the video to extend. |
| num_frames | integer | The number of frames to generate. |
| video_size | — | The size of the generated video. |
| camera_lora | stringenum: dolly_in, dolly_out, dolly_left, dolly_right, jib_up, jib_down… | The camera LoRA to use. This allows you to control the camera movement of the generated video more accurately than just prompting the model to move the camera. |
| acceleration | stringenum: none, regular, high, full | The acceleration level to use. |
| end_image_url | — | The URL of the image to use as the end of the extended video. |
| video_quality | stringenum: low, medium, high, maximum | The quality of the generated video. |
| audio_strength | number | Audio conditioning strength. Lower values represent more freedom given to the model to change the audio content. |
| generate_audio | boolean | Whether to generate audio for the video. |
| guidance_scale | number | The guidance scale to use. |
| use_multiscale | boolean | Whether to use multi-scale generation. If True, the model will generate the video at a smaller scale first, then use the smaller video to guide the generation of a video at or above your requested size. This results in better coherence and details. |
| video_strength | number | Video conditioning strength. Lower values represent more freedom given to the model to change the video content. |
| match_input_fps | boolean | When true, match the output FPS to the input video's FPS instead of using the default target FPS. |
| negative_prompt | string | The negative prompt to generate the video from. |
| extend_direction | stringenum: forward, backward | Direction to extend the video. 'forward' extends from the end of the video, 'backward' extends from the beginning. |
| video_write_mode | stringenum: fast, balanced, small | The write mode of the generated video. |
| camera_lora_scale | number | The scale of the camera LoRA to use. This allows you to control the camera movement of the generated video more accurately than just prompting the model to move the camera. |
| video_output_type | stringenum: X264 (.mp4), VP9 (.webm), PRORES4444 (.mov), GIF (.gif) | The output type of the generated video. |
| end_image_strength | number | The strength of the end image to use for the video generation. |
| num_context_frames | integer | The number of frames to use as context for the extension. |
| num_inference_steps | integer | The number of inference steps to use. |
| 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 used for the random number generator. |
| video | — | The generated video. |
| prompt | string | The prompt used for the generation. |
