Autocut
Autocut, a Fabric utility by skycatminepokie, cuts recordings of gameplay automatically while OBS records the session.
What it does
Autocut connects the game to OBS Studio over OBS's WebSocket server. Once a recording starts in OBS, the mod marks the moments that gameplay produces and asks OBS to cut the video from them, so a long session can be trimmed without manual editing. The mod runs on the client only, so a server needs nothing from it and players keep it on their own machine.
Setup takes a few steps: FFmpeg and OBS must be installed, the WebSocket server has to be enabled under OBS's Tools menu, and the connection password copied into the game. Autocut is published for Fabric only, for game versions 1.20.4 – 1.21.4, and requires Fabric API and YetAnotherConfigLib (YACL). Mod Menu is optional and adds a settings screen. The code is open source under the MIT License.
Its command line can also process an existing recording. Running autocut with a database path and a cut option applies the cutting to an old video. If a cut fails, the original video is moved or deleted rather than left in a broken state, which the author notes as the failure behavior.
Key features
Automatic gameplay cuts
Cuts are made from gameplay events during a recording, so the saved video keeps the parts that were marked.
OBS WebSocket connection
The mod talks to OBS through its WebSocket server, with a password copied from OBS's connection settings.
Offline processing command
A command can run the cutting on a previously recorded video using a database file, with an optional cut option.
Bundled third-party licenses
FFmpeg is included under the LGPL, with the LGPL and GPL license files, a NOTICE file and the Apache 2.0 notices for Fabric API and Fabric Loader.

How it compares
OBS Overlay is also client-side only and open source under the MIT License, but it is published for Fabric and NeoForge across 1.20.5 – 1.21.4 and adds overlays rather than cutting video. Streamer.craft works on either side, and neither side needs it, under the GNU Lesser General Public License v3.0 only, and covers 1.21 – 1.21.10 on Fabric and NeoForge. KillClipper is client-side only, Fabric only, covers 1.19 – 1.21.11 and is not open source.

What the author says
You can also optionally run /autocut finish "path/to/database" to cut an old video. This will fail if the original video is moved or deleted. It also requires a few other things, which are NOT included in the jar - FFmpeg is used under LGPL - This is why there's a LICENSE.lgpl - This is why there's a LICENSE.gpl…
