Install

Trimmy is a Python desktop application. The command you run is small, but it opens a full PySide6 editor.

Requirements

You need:

  • Python 3.10 or newer.
  • ffmpeg on your PATH.
  • ffprobe on your PATH.

Check ffmpeg:

ffmpeg -version
ffprobe -version

If either command is missing, install ffmpeg first.

winget install Gyan.FFmpeg

brew install ffmpeg

sudo apt install ffmpeg

Install with pip

pip install trimmy

Then launch:

trimmy

Run with uvx

If you use uv, you can run Trimmy without installing it into your current environment:

uvx trimmy

Open a video directly:

uvx trimmy "E:\musan\Videos\2026-06-08 23-52-54.mkv"

From source

git clone https://github.com/musantro/trimmy.git
cd trimmy
uv sync
uv run trimmy

For development, run the test suite:

uv run pytest
