FBX vs Rewind

FBX has no write-up on Specifiction yet; its figures are above.

Rewind is free, open-source gameplay replay software for macOS and Windows. It continuously buffers the previous 15–60 seconds of gameplay and saves that window through a hotkey or when a game reports an event. Buffering can pause while you are at the desktop. Capture settings let you choose a display or application, select audio and microphone sources, configure storage cleanup, and rebind hotkeys. Encoding uses Apple VideoToolbox on macOS; Windows options include NVENC, AMF, Quick Sync, and x264. The clip library groups recordings by game and match, offers in-app playback, and shows event-type badges. Steam achievement detection reads local stats-cache files to save labeled clips without an API key or network connection. The README describes League of Legends tracking through its local Live Client Data API, with feature status varying by section. Integrations use sanctioned data sources or screen capture rather than memory reading, injection, or hooking. Rewind is GPLv3 licensed and labeled alpha; Windows capture is not yet validated on real hardware.
