About

Avidemux

Avidemux is a free open-source cross-platform video editor focused on simple single-stream cutting, filtering, and encoding tasks. The project was founded in 2001 by an international open-source community and is released under the GNU General Public License. Avidemux runs on Windows, macOS, Linux, and BSD platforms and remains widely used for lossless cuts, format conversion, and audio-track manipulation without a full timeline editor.

Avidemux was founded in 2001 as an open-source Linux video-editing utility, initially maintained by the developer known online as Mean alongside contributions from Fahad Al-Riyami, Gruntster, and others in the early open-source video community. The project has always positioned itself as a straightforward video editor rather than a full non-linear editor: users open a source file, mark in and out points, apply filters and encoder settings, and save the result. That focused scope has kept the codebase maintainable across two decades of open-source development, and the project is licensed under the GNU General Public License with source hosted on SourceForge and mirrored to GitHub. The application specialises in single-stream operations. Common workflows include lossless cuts on H.264 or H.265 streams, container remuxing between MP4, MKV, AVI, and other formats, audio-track selection and delay adjustment, subtitle burning, batch encoding via the Job Queue, and image-filter chains covering resize, deinterlace, denoise, deblock, IVTC, colour correction, and rotation. Avidemux supports scripted automation through a Python-like scripting language and command-line invocation, which makes it useful in transcoding pipelines and archive projects that need to process large numbers of files without a graphical timeline. The application does not perform layered compositing, multi-track mixing, or advanced colour grading, so users typically pair it with a full NLE for creative work. Avidemux is distributed as free source and prebuilt binaries for Windows, macOS, and Linux, and is packaged for most Linux distributions through their standard repositories, alongside Flathub, the Snap store, and the AppImage program. The project publishes release notes on avidemux.sourceforge.net, maintains a community wiki on fixounet.free.fr, and coordinates development through public issue trackers on SourceForge and GitHub. Long-time contributors, technical archivists, and video-transcoding hobbyists continue to recommend Avidemux for lossless cutting and container remuxing jobs where a full NLE would be overkill.
