# Instant Soundtracks

ElevenCreative launched Instant Soundtracks, which generates an original score for an uploaded video, then analyzes the footage for sound-effect cues and places each generated effect at the matching timestamp on the timeline. Previously music and effects were produced separately and aligned by hand; this update also tightens timing for short-form content and mood switching across scenes, and lets the video's existing audio shape the new score through its genre, crescendos, beats per minute or instrumentation. Effects appear as separate layers in the Music Video Editor, and the API adds add_sfx, separate_tracks and use_audio_as_reference, supporting up to 10 videos per request, 200 MB and 10 minutes combined.
