AI Music Video Editor for Windows.
Edit video to music on your own PC.
MadSync runs on your Windows PC and is built for creators who edit visuals to music. Import your footage and audio, detect beats and tempo, separate stems, generate word-by-word lyric timing, sync effects to beat markers, and finish on a real multi-track timeline. Everything runs locally. Your files stay on your machine. $49 once and it's yours.
Works offline after activation. The only network call is license activation through Lemon Squeezy; after that, MadSync works offline for 30 days before a brief revalidation.

MadSync finds the beats. You shape the edit.
Your track is analyzed locally and beat markers are placed across the timeline. Downbeats, strong hits, medium, weak. All color-coded. Drag them, delete them, add your own. Use them to snap cuts to the music or place each edit by hand. MadSync gives you the map. You decide what to do with it.
Pick a style. Set the intensity. Go.
AMV Classic. Cinematic. Hype Edit. Lo-Fi Chill. VHS Retro. EDM Drop. Hip-Hop Flow. AMV Action. AMV Emotional. Clean Minimal. Lo-Fi AMV. 11 presets. One slider from calm to intense controls how many beats trigger effects and how strong they hit. Every generated effect becomes an editable clip.
Split any song into parts.
One click separates any song into vocals, drums, bass, and other. See where vocals start and stop. See the drum pattern isolated from the rest of the mix. Use what you learn to make better editing decisions. All processed locally on your machine. Nothing uploaded anywhere.
Text on your timeline.
Add text anywhere on the timeline. Customize font family, size, weight, color. Add outlines and shadows. Position presets for top, center, bottom with fine X/Y tuning. Word wrap. Extend across the entire video or drop in for a single moment.
10 effects. Full control.
Flash. Film Grain. Blur. Vignette. Letterbox. Mirror. Color Flash. Brightness and Contrast. Chromatic Aberration. Fade. Place them manually at any moment or let the beat presets handle it. Every effect is editable on the timeline.
Add lyrics to your video.
Drop in any song. MadSync transcribes the lyrics with word-level timing and places them directly on your timeline. Full sentence mode scrolls karaoke-style across the screen. One Word mode highlights each word the moment it's sung. Misheard a lyric? Fix the text, hit Re-sync, and MadSync re-aligns timing for just that section.

Common questions.
-
Yes. MadSync is a desktop alternative to CapCut for Windows users. Pay $49 once and the full editor is yours, including AI auto-lyrics and beat detection. Files stay on your machine.
-
Yes. Drop in a song and MadSync transcribes the lyrics with word-level timestamps. The AI runs locally on your PC, so the song never leaves your machine. Edit any misheard word and re-sync that section without redoing the whole track. Two karaoke modes are included: full-sentence scroll and TikTok-style one-word-at-a-time.
-
Yes. MadSync uses multi-pass AI beat detection to map every beat in the track, then you snap your clips to the beat grid as you edit. The beat tracker is editable, so you can fine-tune anywhere it gets a beat slightly wrong before exporting.
-
No. MadSync is an editor, not a generator. It is built for creators who already have footage and audio and want help with beat detection, stem separation, lyric timing, and beat-synced effects inside a real desktop timeline.
-
Click one button and MadSync transcribes your song with word-level timestamps. Lyrics appear on a dedicated track synced to the vocals. Choose full sentence or one-word-at-a-time display. If a word is misheard, edit the text and click Re-sync. MadSync re-runs just that section with your corrected text and returns precision timing.
-
Import your music into MadSync, click Detect Beats, and MadSync maps every beat on the timeline. Arrange your video clips snapped to those beats, apply a style preset, and export. The beat markers guide your edits so your cuts align with the rhythm.
-

MadSync uses Meta's Demucs to split any song into separate tracks: vocals, drums, bass, and other instruments. This helps you see where vocals start and stop so you can time your edits to specific parts of the music.
