MadSync - AI Music Video Editor

The tool lets creators edit video footage to music on a Windows PC using AI‑assisted beat detection, lyric timing, and stem separation. Users import audio and video, then the software analyzes the track locally, placing color‑coded beat markers and generating word‑by‑word lyric timing that can be dragged onto a multi‑track timeline. Effects and cuts can be synced to those markers, and the editor offers eleven preset styles with an intensity slider to control how many beats trigger visual effects.

Stem separation isolates vocals, drums, bass, and other elements with a single click, allowing precise placement of cuts and text. The interface supports video, audio, voice‑over, and karaoke text layers, and users can export the final edit as MP4 or GIF in any aspect ratio. All processing runs offline after a one‑time license activation, with no telemetry or subscription fees. The program targets music video producers, lyric video creators, AMV editors, and anyone needing a fast, locally‑run editor for syncing visuals to music.
