Download Mustardy

Mustardy is a free, open-source video editor for macOS that trims the pauses for you. Drop in a video, it finds quiet stretches with audio analysis, checks them visually with pixel-diffing, and gives you a clean timeline to cut.

Version 0.1.1 fixes the Mac drag-and-drop and adds visible error messages when a file can't be opened. Runs on Apple Silicon Macs and Linux, fully offline — FFmpeg does the work, nothing leaves your machine.
