11 properties · 2 required · 0 $defs| property | type | description | constraints |
|---|---|---|---|
| image_url* | string | URL of the image to use as the first frame. Must be publicly accessible or base64 data URI. Image dimensions must be between 240 and 7680. | |
| prompt* | string | The text prompt describing the desired video motion. Max 1500 characters. | length ≥ 1 |
| seed | integer | Random seed for reproducibility. If None, a random seed is chosen. | nullable |
| audio_url | string | URL of the audio to use as the background music. Must be publicly accessible. Limit handling: If the audio duration exceeds the duration value (5, 10, or 15 seconds), the audio is truncated to the first N seconds, and the rest is discarded. If the audio is shorter than the video, the remaining part of the video will be silent. For example, if the audio is 3 seconds long and the video duration is 5 seconds, the first 3 seconds of the output video will have sound, and the last 2 seconds will be silent. - Format: WAV, MP3. - Duration: 3 to 30 s. - File size: Up to 15 MB. | nullable |
| duration | enum | Duration of the generated video in seconds. Choose between 5, 10 or 15 seconds. | 5 | 10 | 15 · default: "5" |
| multi_shots | boolean | When true, enables intelligent multi-shot segmentation. Only active when enable_prompt_expansion is True. Set to false for single-shot generation. | default: false |
| enable_prompt_expansion | boolean | Whether to enable prompt rewriting using LLM. | default: true |
| negative_prompt | string | Negative prompt to describe content to avoid. Max 500 characters. | nullable |
| enable_safety_checker | boolean | If set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked. | default: true |

| generate_audio | boolean | Whether the model generates native audio for the video. Set to false for silent video generation, which is cheaper (half as much as a flash generation with audio)Independent of audio_url, which only provides a track to sync the video against. | default: true |
