Valve's in-house movie-making machine, the Source Filmmaker, is now available to the public in beta form. Source Filmmaker is the tool Valve uses to create its own films, including the "Meet the" series for Team Fortress 2: Valve teased the Source Filmmaker at the end of today's long-awaited, disturbingly depressing "Meet the Pyro" video.

The Source Filmmaker can make a movie out of any game running on the Source engine, Valve writes in the tool's introductory post.

"Because the SFM uses the same assets as the game, anything that exists in the game can be used in the movie, and vice versa. By utilizing the hardware rendering power of a modern gaming PC, the SFM allows storytellers to work in a what-you-see-is-what-you-get environment so they can iterate in the context of what it will feel like for the final audience."

Interested amateur directors can sign up for the Source Filmmaker beta right here and "start shooting your movie on location inside the world of TF2 today."
