KeyCut is a free, open-source (MIT) video editor that cuts and joins videos without re-encoding. It splits video at keyframes, so cuts snap to instantly-decodable frames and exports are direct copies - original quality, no waiting.

Features: lossless cut & join; export kept segments as one file or per marker; split/delete/restore/merge on the timeline; optional x264 compression presets (720p/1080p/1440p/2160p); audio waveform view; keyframe snapping; re-key at 2/6/10 fps.

For Windows, macOS (arm64) and Linux (x64).
