Input

Field	Kind	Default	Description
`video_url` required	URL or file	—	Public http(s) URL of the source video to score.
`keep_speech_vocal`	true or false	false	Keep the original video's speech/vocals. When on, the source audio is separated (music source separation), and only the isolated vocals are blended over the generated music with automatic ducking (the music dips under speech). When off (default), the original soundtrack is dropped and the video carries only the generated music.
`num_samples`	number (whole) 1 to 3	1	How many distinct scored videos to generate.
`prompt`	text	—	Optional text prompt steering the musical style. If omitted, a prompt is generated automatically from the video.
`prompt_influence`	number 0 to 1	0.5	Turn it up to match the text prompt
`start_offset`	number 0 to 600	—	Optional. Start scoring from this offset (seconds) into the video. Requires Start Offset + Duration <= Video Duration.
`duration`	number 1 to 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 (None) to the rest of the video.
