Úvod

Kdenlive is an acronym for KDE Non-Linear Video Editor.

It is a free software (GPL licensed) primarily aimed at the Linux platform, but it also works on BSD[1] as it relies only on portable components (Qt and MLT framework). Windows versions are also available, with some drawbacks. See Windows Issues for more information. A port on MacOS is also available.

Through the MLT framework Kdenlive integrates many effects for video and audio processing or creation. Furthermore, Kdenlive brings a powerful title editor, a subtitling feature with AI-supported speech to text conversion, nested timelines (new in version 23.04), animation support through Glaxnimate integration (new in version 22.08) and thus can be used as a complete studio for video creation.
