| Parameter | Type | Required | Default | Min | Max | Allowed Values | Description |
|---|---|---|---|---|---|---|---|
video | file | Yes | - | - | - | - | The video to score with a new soundtrack. The model analyzes its pacing, mood, and visual rhythm to produce music that fits, then muxes it back into the video. Cost scales with video duration. |
prompt | string | No | - | - | - | - | Optional style guidance for the generated music. If omitted, Sonilo generates a prompt from the video. |
keepSpeechVocal | boolean | No | false | - | - | - | When enabled, the original speech/vocals are isolated and blended over the generated music with automatic ducking. When off (default), the original soundtrack is replaced entirely. |
numSamples | number | No | 1 | 1 | 3 | - | How many scored video variations to generate from the same source. Useful for picking the best fit. Each additional sample adds to the cost. |
startOffset | number | No | - | 0 | 600 | - | Optional. Start scoring from this offset in the video, in seconds. Start offset plus duration must not exceed the video duration. |
duration | number | No | - | 1 | 600 | - | Optional. Length (seconds) of the video segment to score. When set, scores a segment of this length starting at Start Offset (or from the beginning if Start Offset is unset). Defaults to the rest of the video: the whole video when Start Offset is unset, or from Start Offset to the end when it is set. |
