What is it?

Kdenlive is a non-linear video editor that is free and open source. It targets users from simple home-video cutting to larger multi-track projects, and is built on the MLT multimedia framework for its editing engine.

The application is written in C++ and uses Qt together with KDE Frameworks 6 for its interface. Video effects are supported through frei0r and audio effects through LADSPA.

Development happens primarily on KDE Invent, with a GitHub mirror. Code contributions are submitted through KDE's GitLab, and the project also welcomes help with translation, bug triage, documentation and tutorials.
