Kdenlive
FreeA professional-grade free video editor from KDE
Unlimited audio and video tracks, rich effects and transitions, color grading, audio post and subtitle tools — built on FFmpeg to edit almost any format directly, fully free with no watermark.
Why we picked it
Maintained by the KDE community for years, Kdenlive is a non-linear editor whose feature depth rivals commercial software: unlimited tracks, keyframe animation, proxy editing, plenty of effects and transitions, and a built-in subtitle editor that holds up on complex projects. Thanks to FFmpeg, almost any format drops straight onto the timeline.
It's fully open source across all three desktop platforms, with no watermark, no paywall, no forced account, and no telemetry by default. For anyone serious about learning to edit without spending money, it's a tool you can rely on long-term.
