Edit video to music without timeline guesswork
MadSync is built around the music. It brings beat detection, stem separation, lyric timing, overlays, effects, and local export together in one Windows app, so your edit follows the song.
Find the beat faster
One click reads the beat from the drum stem and drops markers on the timeline: downbeats, strong, medium, and weak beats, plus drum hits.
Snap your cuts to them, then build Beat FX, transitions, Beat Drops, and beat-synced visuals on the same grid so everything moves with the music.
Sync lyrics by word
Create karaoke-style captions, adjust word timing, and style text on the timeline. Show lyrics as a single line, a short stack of recent lines, or a full paragraph block, and lyric motion effects (fade, scale pop, pulse, glow, color cycle, and more) play in all three, matching between preview and export.
Export without uploading
Your media never leaves your computer, and the AI runs locally too.
Stem separation, lyric transcription, and beat detection all happen on your machine.
Edit, process, and export finished video for YouTube, Shorts, Reels, promos, and client work.
Built for lyric videos, AMVs, Shorts, Reels, and artist promos
MadSync finds the beats. You shape the edit.
Your track is analyzed locally and beat markers are placed across the timeline: drum hits, downbeats, strong hits, medium hits, and weak hits.
Drum hits ride the isolated drum stem and are best for hard cuts and Beat FX. All markers are color-coded so you can see the structure of the song at a glance.
Add manual beats, remove beats, and use the beat map to line up cuts, effects, lyrics, and visual moments. MadSync gives you the map. You decide what to do with it.
Pick a style. Set the intensity. Go.
Choose from 11 Beat FX presets: AMV Classic, Cinematic, Hype Edit, Lo-Fi Chill, VHS Retro, EDM Drop, Hip-Hop Flow, AMV Action, AMV Emotional, Clean Minimal, and Lo-Fi AMV.
One intensity slider controls how many beats trigger effects and how hard they hit.
Presets ride drum hits when available, or the beat grid otherwise.
Generated effects become editable timeline clips, so you can adjust or remove anything after the preset runs.
Split supported songs into stems.
MadSync separates supported songs into vocals, drums, bass, and other stems.
Use the vocal stem to understand where lyrics start and stop.
Use the drum stem to see the rhythm more clearly.
Use the separation to make better editing decisions. Stem processing runs locally on your machine.
Nothing is uploaded.
Text on your timeline.
Add text anywhere on the timeline.
Pick the font family, size, and weight, then set the color, an outline, and a soft shadow.
Add a background box with its own color, opacity, and padding when you want the words to stay readable over busy footage.
Place it with top, center, and bottom presets, then fine-tune X and Y. Set the opacity, and long lines wrap to fit the frame on their own.
Animate it in with Fade In, Type On, Bounce, Glitch In, or Beat Pulse. Hold text across the whole video, or drop it in for a single moment.
21 effects. Full control.
Add animated rain, snow, clouds, dust, embers, or light leaks over a single clip or the whole song.
It is a fast way to give lo-fi, chill, and cinematic edits a finished, moody feel.
Pick a style and set its opacity, drift speed, and blend.
The motion is ambient, so it sets a mood across the whole shot instead of pulsing on the beat, and the look you see in preview is the look you get in the export.
Lo-fi atmosphere overlays
MadSync ships 21 timeline effects in two groups. Look & style: Flash, Color Flash, Fade, Film Grain, Blur, Vignette, Letterbox, Strobe, Chromatic Aberration, Brightness/Contrast, Glow Pulse, and Mirror.
Motion: Beat Zoom, Beat Shake, Punch Zoom, Pull Zoom, Directional Shake, Rotate Bump, Bounce Pop, Whip Blur, and Slow Drift.
Place any effect by hand at any moment on the timeline, or let Beat presets generate editable, export-safe effect clips for you.
Audio-reactive visualizers on your video.
Choose from 8 styles: Audio Bars, Mirrored Bars, Waveform Ribbon, Neon Equalizer, Pulse Wave, Minimal Line, Frequency Mountain, and Spectrum Bars Pro.
Set the color, opacity, height, and placement (top, center, bottom, or custom).
Turn on Beat Boost (subtle or strong) to make the visualizer pulse on every detected beat, locked to your beat grid instead of a generic loudness follower.
Add lyrics to your video.
Use Auto Lyrics to transcribe straight from the audio, or use Paste Lyrics for the most accurate word-level alignment.
MadSync places karaoke-style lyric clips right on your timeline.
In Full Sentence mode the whole line stays on screen and each word lights up as it is sung.
One Word mode shows a single word at a time, the TikTok and Reels look.
If a word is wrong, fix the text and hit Re-sync to realign the timing for that section.
Export for the major social platforms.
Export for YouTube, TikTok, Instagram, Reels, Shorts, and other common upload destinations.
Render MP4 or WebM at 720p or 1080p, or save a short clip as a GIF. Pick 16:9, 9:16, 1:1, or 4:5 to match where it is going.
Lyrics are baked into the video. Transitions, overlays, effects, and timeline edits all render into the final file.
Fast export uses hardware-accelerated H.264 when your computer supports it, and falls back to software so it still works everywhere.
