Hand it a finished video, get back an original score matched to the cut — pacing, motion, and emotion drive the composition, and length matches the video exactly. No prompts, no manual syncing.
▶ Watch an example — an AI-generated trailer scored entirely by video_to_music.
- 🎵
text_to_music— generate a track from a text description (genre, mood, tempo, instrumentation) at an exact duration. - 🔊
video_to_sfx/text_to_sfx— sound effects matched to a video, or generated from a plain-text description. - 🎧
video_to_sound— music and SFX for the same clip in one call, mixed into a single soundtrack. - 🎬
video_to_video_*— the same music / SFX / sound generations, but you get a finished video back with the audio already muxed in. - 🗣️
dubbing— re-voice a video into other languages. - 🎚️
audio_ducking— automatically duck a music bed under a voice track.
