KillClipper
by dro8y
KillClipper records a clip automatically each time a player gets a kill, by connecting Minecraft to OBS Studio over the OBS WebSocket plugin.
What it does
KillClipper connects Minecraft directly to OBS Studio through the OBS WebSocket plugin. When a kill is detected, the mod asks OBS to save the replay buffer, so almost every kill is captured without any manual step. Kill detection works in two modes, and the mod then sorts each saved clip into a folder for the player who made the kill.
Setup happens in the mod's config screen, reached through Mod Menu. There the OBS WebSocket server port and password are entered, and the recording path is set. OBS itself needs its WebSocket server enabled and the replay buffer turned on in its output settings. The mod is built for Fabric on 1.19 – 1.21.11 and runs on the client alone, so no server install is needed. Cloth Config API, Fabric API and Mod Menu must also be installed.
Key features
Automatic kill clips
The replay buffer is saved when a kill happens, so the clip covers the moments before the kill.
Two detection modes
Kills can be found by reading the game state or by watching specific kill messages in chat, depending on the mode chosen.
Per-player folders
Saved clips are moved into folders named for each player, so kills from several players stay separated.
Config screen
The OBS WebSocket address, port, password and recording path are set from a screen opened through Mod Menu.

Use cases
Recording a multiplayer session
A player streaming or recording a server can keep a clip of each kill without pressing a key during the fight.
Organizing kill footage
Clips from a long session are already grouped by player, which makes them easier to find afterward.
Who it’s for: Players who stream or record Minecraft with OBS Studio and want the kill moments saved without manual capture. The mod is useful to anyone who keeps a running kill log in their recordings.
