Best Apps to Make Bouncing Ball Music Videos (2026)

The best app for making bouncing ball music videos depends on how you want the music to drive the ball: Marble Music turns a song or MIDI file into a level where the marble bounces on every note, while browser simulators like BallEngine and BallTok start from a physics scene and sync a MIDI melody to the bounces. If you'd rather tinker, Ball Chaos is an iPad and iPhone physics playground, and the DIY route of a Pygame script, OBS Studio and CapCut gives you full control at the cost of writing code.

A quick disclosure: I make Marble Music (formerly Beat Bounce), so read this as a developer's view. Everything said about the other tools below comes from their own websites or store listings as of October 2026, and I've left out anything I couldn't confirm there. Features and plans change, so check each link before you commit.

The comparison at a glance

Tool	Where it runs	How the music drives the ball	Export	Effort to first video
Marble Music	iOS, Android, Steam (Windows, macOS)	Built from a song or imported MIDI; the marble bounces on every note	Render in up to 4K	Low
Ball Chaos	iPad and iPhone; Apple silicon Macs and Apple Vision Pro per the listing	Physics scenes, with a Music Square mode among its modes	Record clips for TikTok, Reels and Shorts	Low to medium
BallEngine	Web browser	In its Rhythmic Mode, every bounce plays the next note of a song or MIDI file	Video export for YouTube, TikTok and Instagram	Medium
BallTok	Web browser	MIDI melodies synced to the bounces	HD video export	Medium
DIY: Pygame + OBS + CapCut	Desktop	Whatever you program	Whatever you record and edit	High

"Effort" is my own judgment of how much setup stands between installing the tool and posting a clip, not a measured number.

Marble Music: start from the song

Marble Music is a free rhythm game with in-app purchases. You either play a song from its library of piano, chill and classical tracks, or import a MIDI file in the level editor, and the marble bounces on every note. You can edit the level afterward, choose one of the glowing visual themes, and render the video in up to 4K for TikTok, Instagram Reels or YouTube Shorts. Check the store listing for what the in-app purchases include.

Pick it if: you think in songs rather than physics settings, you want to make videos on your phone, or you want a desktop version through Steam.

Worked example: download the Canon in D MIDI from the site's 1,100+ free MIDI files, import it in the level editor, play it once to check the feel, and render. The step-by-step TikTok tutorial covers that flow in detail.

Physics-first tools: Ball Chaos, BallEngine and BallTok

These three start from a physics scene, such as balls in a ring, colliding shapes or a race, and let you shape the motion. Here is what each one's official page says today.

Ball Chaos

Ball Chaos - Visual Playground by Michal Manak is a free download with in-app purchases on the App Store. Its listing describes customizable physics scenes with bouncing balls, colliding squares, motion trails and color effects, plus structured modes such as Square Race, Music Square, League and Match. It's pitched at creators recording short loops for TikTok, Reels and Shorts. The listing's title varies by country, so search for "Ball Chaos" if the link opens a different name.

Pick it if: you're on an iPad or iPhone and want to play with physics settings and visual effects by touch.

BallEngine

BallEngine is a bouncing ball simulator that runs in the browser. In its Rhythmic Mode, you pick a track from its song library or drop in your own MIDI file, and every bounce plays the next note. It has other modes too, such as an escape mode where balls break out through rings. Its FAQ says a paid plan removes the watermark from exports.

Pick it if: you work on a computer, want many simulation styles in one place, and like the "the collision plays the note" look.

BallTok

BallTok is a web-based bouncing-ball physics simulator aimed at TikTok, Shorts and Reels creators. You pick a physics mode, adjust it, sync a MIDI melody to the bounces and export an HD video. Check its site for what the free and paid plans include.

Pick it if: you want preset physics modes in the browser without installing anything.

The DIY route: Pygame, OBS Studio and CapCut

If you can write some Python, you can build the whole thing yourself:

1. Simulate. Pygame is a free, open-source Python library for games and multimedia. It can draw shapes, play sounds and run a game loop, but the physics and the note timing are code you write.
2. Capture. OBS Studio is free, open-source recording software for Windows, macOS and Linux. Record the Pygame window at a vertical size.
3. Edit. CapCut runs on desktop, mobile and the web and can auto-generate captions. Trim the start, add the song title on screen, and export.

Pick it if: you want a look nobody else's tool produces and you enjoy the coding as much as the posting.

Which one should you pick?

• You want a finished video from a specific song tonight: Marble Music. Import the MIDI, play, render.
• You only have an iPad or iPhone and want to experiment with physics: Ball Chaos.
• You're on a school or work computer and can't install anything: BallEngine or BallTok in the browser.
• You want full creative control and can code: Pygame, OBS and CapCut.
• You want to post classical pieces safely: any tool, fed with a public-domain piece. A public-domain composition doesn't make every MIDI arrangement free to use, so check the license of the file.

If your audience is piano learners, a free-floating marble may not be the best fit. Note Bounce is our sister rhythm game where bouncing balls land on real sheet music, so viewers see the actual notes on a staff as the melody plays. It imports MIDI and renders gameplay videos too, which makes it a different look for the same piano piece.

Try it

Pick one public-domain piece, make it in two tools from the table, and post both to see which look your viewers stay for. For the song-first approach, start with Marble Music.
