Source Filmmaker is Valve’s movie-making tool for creating films inside the Source game engine. Rather than being a conventional game built around a player-controlled character or campaign, it is designed for storytellers to stage and produce movies using the engine’s game assets. Its connection to the underlying games is central to the concept: assets can move between the game and the movie-making environment.
The tool’s workflow is built around a what-you-see-is-what-you-get environment, rendered using a modern gaming PC’s hardware. That lets creators iterate while seeing their work in context of how it will feel to an audience. Source Filmmaker includes the base assets from Team Fortress 2 and assets from some of the first Meet the Team short films, giving users material to work with as they make their own productions. The Steam listing also identifies Steam Workshop as a category.
Its specific appeal is the ability to make movies within the Source engine, drawing on assets that connect the tool to the games and short films built with them.
