KeyCut is a free, cross-platform desktop video editor for cutting and joining video without re-encoding. Like other lossless editors, it works by splitting a video at its existing keyframes and splicing the kept segments back together, so a cut that would otherwise take minutes of rendering completes almost instantly with no quality loss.
What sets it apart from a simple trim tool is a full timeline-based editing workflow. Segments can be split, deleted, restored, and merged directly on a visual timeline with an audio waveform, and multiple segments can be selected and edited together. Cut points can be marked and named, and the kept segments can be exported either as one combined file or as separate files per marked block. An optional compression pass with common resolution presets is available for cases where a lossless-only export is not needed. For recordings made in OBS specifically, the project documents how to configure a shorter keyframe interval so that cuts can land closer to the exact frame intended, trading a modestly larger recording file for finer-grained editing precision.
KeyCut is placed in Tools / Assess, at the outer edge of the ring. The project was first published on 2026-09-08 and has accumulated 16 stars with no open issues recorded as of this writing, which reflects its very short track record rather than confirmed stability. It ships under the MIT license with builds available directly from GitHub Releases. Its differentiation from LosslessCut is the addition of a marker-and-timeline editing model rather than single-pass trimming, which is worth revisiting once the project has more history and any first-person use.
