TapMV — a free YTPMV & otoMAD maker in your browser

Last updated: 10 November 2026

TapMV turns the hardest part of making a YTPMV or otoMAD (音MAD) — getting the picture to hit the music — into tapping along. Every tap is a trigger, and on each one your clips jump, spin, flash, flip or change colour.

It's free, with nothing to install and no account. Everything you load stays in your browser; nothing is uploaded.

What is a YTPMV / otoMAD?

A YTPMV (YouTube Poop Music Video) is a video in which a song is played with sounds taken from source clips — a voice, a sound effect, a line from a show — and the picture shows those clips on every note. The name comes from the YouTube Poop scene, and split-screen layouts with several clips playing at once are common.

OtoMAD (音MAD) is the name that grew up on Japanese video sites for much the same thing, and it covers a wider range: from songs played entirely with source sounds to videos that cut clips and lines to an existing song. The line between the two is blurry, and the same video is often called both.

How to make a YTPMV, step by step

1. Pick a songStart short — a chorus, or 15–30 seconds, is plenty for a first one. A song with a clear, steady tempo (BPM) is easier to match.
2. Collect your sourcesThe clips you'll take sounds and pictures from. Check the rights holders' guidelines and the rules of the site you'll post to.
3. Make the sound (optional)Cut single sounds out of your sources, tune them to the melody, place them as notes on a piano roll in a DAW, and balance the volumes. For a first video, you can simply keep the original song.
4. Sync the picture to the soundMake the clips appear, bounce, flash or flip on each note. By hand this is the slowest part — and it's where TapMV comes in: tap along to the song, and every tap fires your effects. If your notes are already in a DAW, export them as MIDI and use “Import MIDI” in “4. Record”: each track (or each drum pitch) becomes a take of its own, so each clip can follow its own part.
5. Export and postWrite it out as a video file, watch it all the way through, and post it. If it flashes a lot, add a warning for viewers who are sensitive to light.

What you can do

• Tap a key (or the on-screen pad) along with the song, and your effects fire on every tap
• Use images, videos and GIFs — or make shapes, text and audio waveforms right in the app
• Lyrics and other text move on a line per tap — typed out letter by letter, coloured in karaoke-style, or with each letter moving a moment after the last
• Effects that would take a copy and a keyframe per tap in an editor are one tile here: copies left behind on each tap (stamps), or falling and piling up; a row of copies taking the taps in turn, or swapping places; the picture broken into tiles that shuffle; a combo counter; bouncing off the screen edges, a new colour each hit
• About 90 effects in four kinds: Pulse (plays once per tap), Toggle (switches on and off with each tap), Step (builds up with each tap) and Constant (always on) — see them all moving
• Give each clip a clipping frame for split-screen layouts, and move each clip to a rhythm of its own
• Show a clip only while it's being played, coming in and going by a move, a wipe, a shatter or a hop into the abyss — and hand the screen from one clip to the next in one move (a push, a knock-off, a wipe, a turn-over, a hop and drop, a light passed across), the next one all there on its first tap. The taps are recorded first, so TapMV knows when each turn begins: no keyframes to line up
• Trigger from a rhythm pattern, or turn the notes of a MIDI file from your DAW into taps — and let the notes' pitch move a clip up and down, or lay the notes out as a scrolling piano roll
• Export MP4, WebM (transparency kept) or GIF, on a transparent, green-screen, blue-screen or any-colour background

How it works — five steps

1. AudioLoad the song (an audio file, or a video with sound) and its BPM (to a hundredth, so the grid holds to the end) and where its bars start are guessed for you — type it or tap along to measure it if it's off.
2. MaterialsPlace your clips on the screen: drag them, resize them by the corners, or type in exact values. Several added at once are laid side by side, to size or move together.
3. EffectsPick each clip's effects. Press the trigger to try them out on the spot, without recording anything.
4. RecordPlay the song and tap the trigger key (J to start with; change it if you like). Fine-tune the taps on the waveform afterwards, snapping them to the beat or to the onsets in the audio, or quantizing them all to a grid (1/16 and so on, at a strength you choose); a take tapped late (or early) throughout moves whole with the Timing knob by the take (“Fit to the song” finds where it sits on the song's hits); if you're always early or late, “Timing offset” can measure it for you — tap along to clicks and then to flashes, and it works out the preview's picture delay too (Bluetooth earphones), or tap along to the song itself. Turn on “Loop the range” to record a stretch over and over — a new take each time round, or laid over the last, or replacing it. Record a separate take for each clip to move them to different rhythms.
5. ExportPlay it all the way through in the preview (full-size if you like), then choose MP4, WebM or GIF, with or without the song, and the background you want — at full size or scaled down (half, say).

What you need

Desktop Chrome or Edge (latest) with a keyboard works best. Phones and tablets work too, with the on-screen trigger pad. MP4 and WebM export needs a recent browser (GIF works everywhere); on older Safari, a few colour and blur effects may not show.

Questions

Is it really free?

Yes. No install, no sign-up, and no ads at the moment.

Are my files uploaded?

No. Your audio, clips and projects are processed and kept in your browser only. See the privacy policy.

Where is my work saved?

In your browser, automatically. Clearing your browser's site data clears it too, and Safari may clear it after seven days unused (on an iPhone or iPad, opening TapMV from “Add to Home Screen” helps) — so keep a copy with “Save”, and open it anywhere with “Open”.

Can I monetise what I make?

The videos you export are yours (TapMV claims no rights), monetisation included. The rights to the songs and clips you use are their owners' — follow their wishes and the rules of the site you post to.

Do I need to credit TapMV?

It's optional, but very welcome: a line like “Made with TapMV (https://tapmv.org)” in the description helps others find it.
