KDEnlive

Kdenlive is a free and open-source non-linear video editor designed for cross-platform use. It runs on Linux, Windows, and macOS. The project is part of the KDE community and aims to provide a feature-rich editing tool for both hobbyists and professionals. Kdenlive is distributed under the GNU General Public License.

Its core is a timeline-based editor that allows multiple video and audio tracks, drag-and-drop clip management, and a variety of transitions and effects. Users can apply color correction, keyframe-based animation, audio mixing, and titles. The software supports proxy editing to improve performance on lower-powered machines, and it includes project templates and customizable keyboard shortcuts.

Under the hood, Kdenlive relies on the MLT Framework to manage media processing and transitions, the FFmpeg libraries for decoding and encoding, and a range of frei0r and other plugins for effects. It uses Qt for its user interface and integrates with other KDE applications. It supports a broad set of media formats and allows rendering to common codecs and containers such as MP4, MKV, and AVI.

Development is ongoing with regular releases and an active user and developer community. Documentation and user guides accompany the project to assist new users in learning the interface and workflows. Kdenlive has become one of the prominent open-source video editors, widely used on Linux and increasingly available on other platforms.
