After literally years
of anticipation, the final video in Team Fortress 2's excellent 'Meet The Team' series has been released. Alongside it, Valve have announced that their internal video creation software (used for the Meet The... videos, as well as basically all their marketing and cutscenes for the past few years) is to be released publicly.
There's a decent look at the software being released over at the official site for Source Filmmaker
, where you can also sign up for the beta, and read more about what exactly we can expect when it does release.
