Edit video to music without timeline guesswork
Generic editors give you a timeline. MadSync adds the music-first tools creators actually need: beat markers, BPM detection, stems, lyric timing, overlays, effects, and local export in one focused Windows app.
Find the beat faster
Detect BPM, generate beat markers, and cut footage around the musical structure instead of hunting through the waveform by hand.
Sync lyrics by word
Create karaoke-style captions, adjust word timing, style text, and preview lyric effects directly on the timeline.
Export without uploading
Keep your media on your computer. MadSync runs local processing and exports finished MP4 files for YouTube, Shorts, Reels, promos, and client delivery.
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: downbeats, strong hits, medium hits, and weak hits. They 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. 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. Customize font family, size, weight, color, outlines, and shadows. Use top, center, and bottom position presets with fine X/Y tuning. Turn on word wrap. Extend text across the full video or drop it in for one moment.
10 effects. Full control.
Flash. Film Grain. Blur. Vignette. Letterbox. Mirror. Color Flash. Brightness/Contrast. Chromatic Aberration. Fade. Place effects manually at any moment on the timeline. Beat presets can also generate editable, export-safe effect clips automatically.
Add lyrics to your video.
Use Auto Lyrics to transcribe from audio, or paste your own lyrics for more accurate word-level alignment. MadSync places karaoke-style lyric clips directly on your timeline. Full sentence mode displays lyrics across the screen. One Word mode highlights each word as it is sung. If a lyric is wrong, fix the text and use Re-sync to realign timing for that section.
Export for the major social platforms.
Export MP4 videos for YouTube, TikTok, Instagram, Reels, Shorts, and other common upload destinations. Use 16:9, 9:16, 1:1, or 4:5 aspect ratios. Choose 720p or 1080p for MP4/WebM exports, with GIF export available separately. Lyrics are baked into the video. Transitions, overlays, effects, and timeline edits render into the final file. Fast export uses hardware-accelerated H.264 when available, with software fallback.
