time.sleep(5)Request parameters supported by the Sonilo Video to Video API on EmpirioLabs. Defaults apply when a field is omitted.
| Parameter | Type | Default | Range / values | Description |
|---|---|---|---|---|
| mode | enum | music | music, effects, music_and_effects | What to add to the returned video: a generated soundtrack, frame-synced sound effects, or both mixed together. |
| prompt | string | - | - | Creative direction for the generated audio. |
| music_prompt | string | - | - | Direction for the music bed. |
| sfx_prompt | string | - | - | Direction for the sound effects. |

| ducking | boolean | false | - | Dip the kept voice under the generated audio instead of holding a static mix. |
| variants_num | number | 1 | 1 to 10 | How many differently scored videos to generate in one request. Each variant is billed separately. |
| prompt_influence | number | 0.5 | 0 to 1 | How strongly the music follows the prompt rather than the footage. Lower lets the video lead. |
| segments | string | - | - | JSON array of timed segment prompts for scene by scene direction. Each entry takes start, end and prompt in seconds. |
| video_url | string | - | - | Source video, as a publicly reachable URL. Up to 300MB and 8 minutes. Uploading a video in the playground sets this for you. |
