The marble video feeling, played by a real guitar.
The satisfying part of a marble video is anticipation: you see the motion and you know the note is coming. Here that feeling comes from the instrument itself. A photoreal 3D guitar plays your actual music: strings light up on the beat, at the fret the song asks for, and a pick works the soundhole.
Five looks take the same song from neon stage to black lacquer to golden hour. The light, the scene and the camera answer the music, not the other way around.
Is this a marble music video maker?
No. Marble music videos come from apps that roll marbles down a course where every collision plays a note, and one specific app owns that genre. Neural-Fretboard makes a different video from the same starting point: you load your own MIDI or Guitar Pro file and a photoreal 3D guitar performs it, with every note lighting the exact string and fret a guitarist would use, while a pick works the strings. You choose one of five looks or design your own scene, then export a 9:16 or 16:9 video rendered entirely in your browser. The free plan includes three full 1080p videos a month with no watermark. If the marble app has your song, use it. If the music you want is your own file, this is built for exactly that.
Marble run videos vs a 3D guitar performance
The genres share one trick, anticipation before the note lands. They differ in what makes the sound and whose music plays.
| Marble music apps | Neural-Fretboard 3D Guitar | |
|---|---|---|
| The star | Marbles rolling through a note course | A photoreal guitar playing real fingering |
| Your music | Course built for a chosen track | Your own MIDI or Guitar Pro file, the whole band plays |
| Musical truth | Collisions timed to the melody | Every note on the string and fret the tab says, capo and tunings included |
| Styling | Track themes | Five looks, body finishes, lighting, your artwork on the instrument |
| The video file | Depends on the app | Direct 9:16 or 16:9 export, rendered locally, no upload |
| Price | Varies | Free: 3 videos a month at full 1080p, no watermark |

What you get, honestly
- Free plan: 3 videos a month at full 1080p with no watermark, all 5 built-in looks.
- Creator plan: unlimited videos at 60 fps, custom looks, your own 3D objects and artwork.
- The guitar plays real fingering on the neck, which is why the videos read as a performance instead of a screensaver.
- Works on normal laptops: a two-pass export keeps the final file smooth even when the live preview cannot keep up.
