MV Toolkit

Hand it an MP3 and get a music-reactive MV. Detects chord progressions and visualizes them on the Circle of Fifths — a music theory-based MV production environment.

Emocute MV Toolkit is an MV production environment that runs inside Claude Projects. Just hand it an MP3 — it automatically detects BPM, chords, separates stems, and analyzes song structure, then generates music-reactive MVs from 41 WebGL shader templates. No other tool combines Circle of Fifths visualization, WebGL shaders, and automatic MV generation in one package.
