Input

Field	Kind	Default	Description
`video_url` required	URL or file	—	The video to add sound to (public URL, or upload a file). The generated audio matches the video's length.
`prompt`	text	—	Optional. Describe the kind of sound you want; it steers the generated audio for every scene. Leave empty to caption the video automatically.
`segments`	JSON	—	Optional. Split the video into time ranges, each with its own sound description. Leave empty to split into scenes automatically.
`audio_format`	one of wav, mp3, aac, flac	aac	Format of the returned audio file: aac (default), mp3, wav, or flac. (The video with sound is always AAC.)
`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 the isolated vocals are kept as recorded, with the generated sound mixed in at a level matched to the voice; the rest of the original soundtrack (music, ambience) is dropped. Applies to the returned audio and video. When off (default), the result carries only the generated sound.
