FlashbackClipper

A replay buffer runs in the background while a world is played and keeps only the most recent minutes of footage, in the way an OBS replay buffer does. Older footage leaves the buffer as new footage arrives, so disk use stays flat however long the session lasts. Pressing the Save Clip control, or F9 from the pause menu, writes the buffered span out as a regular Flashback replay that opens in Flashback's replay browser and editor, alongside recordings made the normal way. The buffer and a standard Flashback recording can run at the same time, and stopping the world discards whatever the buffer still holds.

Built on top of Flashback by Moulberry, the mod depends on Flashback for recording and playback, and Simple Voice Chat is optional: when it is installed, saved clips include voice chat conversations. The buffer is controlled from the pause menu through a Start Replay Buffer button placed next to Flashback's recording controls. Settings for the mod sit under a FlashBack Clipper heading in the config screen of Flashback, which ModMenu opens. The mod is published for Fabric only, for 1.21.11, 26.1.2 and 26.2, and runs on the client alone.
