Input
Master song and camera clips.
The tool listens for the song in camera audio and compares that audio to the selected master track.
DaVinci Resolve music-video sync
Sync music-video takes to the master song before the edit starts.
KFS Music Sync is built for the part of music-video editing that is painfully mechanical: finding where each camera take belongs against the finished track.
The real search problem
Music videos are not only a beat-editing problem.
A beat editor can help you cut on rhythm. KFS Music Sync solves an earlier job: placing performance takes so the editor can review material against the master song. It is especially useful when a project has repeated choruses, false starts, partial performances, b-roll, and many clips recorded to playback.
Output
Reviewable Resolve timelines.
Confident matches can land in a synced performance timeline, while uncertain clips remain visible for review.
Boundary
Orientation, not final edit.
The generated timeline helps the editor start cutting. It does not choose the performance, pacing, color, or story.
Best fit
Use it when the music was played during takes.
Good fit: music videos, dance films, performance clips, rehearsal coverage, and repeated takes recorded with song playback.
Weak fit: dialogue scenes, traditional timecode multicam, corporate interviews, or footage where the camera audio has no useful version of the song.
Human review still matters: quiet, distorted, partial, or off-speed clips may need editor judgment.
