What Source Filmmaker is
Source Filmmaker is Valve’s free tool for making films inside the Source game engine. It brings rendering, keyframing, motion-capture editing, and sound editing into one workflow, with hardware rendering for a real-time preview while scenes are being refined. Its initial release includes nine characters, hundreds of locations, and thousands of props, particles, textures, and sounds from Team Fortress 2. Source-engine assets created for the TF2 Workshop or game mods can be recompiled and loaded into SFM. Finished movies can be uploaded to the web or shared as regular movie files. SFM is released for Team Fortress 2, and the TF2 build can be modded to create new worlds. The tool requires Steam to install and is supported on Windows, not Mac. Valve assets may be used in free community movies and images, but that permission does not cover commercializing those assets. Content made without Valve assets may be monetized without restrictions stated in the FAQ. Steam requires at least 15 GB of hard-drive space.
