A non-developer used Claude Code to build a Premiere Pro plugin
Music video editing often requires cutting clips exactly on the beat, but manually tapping out every beat and adding markers takes time. Claude Code was used to build BeatMarker, a small plugin that s that job. BeatMarker lets the editor choose a WAV or MP3 file, analyze it, and place colored markers on each beat in the clip.
The first beat is marked red, the backbeats are marked blue, and beat three is marked yellow. The editor can then cut directly to those markers. The marker positions can also be shifted with arrow controls.
The plugin is free and , works on Windows and macOS, and supports Premiere Pro 2025 and 2026. It still has limits: for now, it only supports 4/4 time and music with a steady tempo.
