Source Filmmaker (abbreviated as SFM) is a video capture and editing application that works from inside the Source game engine.[6][7] The tool, created by Valve Corporation, was used to create over 50 animated shorts for its Source games, including Team Fortress 2, the Left 4 Dead series, and Half-Life 2. On June 27, 2012, Valve released a free open beta version of the SFM to the gaming community via its Steam service.
