Made by Etienne Perot.

Utility to render high-quality, smooth Source Engine movies using a customized userspace filesystem that catches the frames before they are written to disk. Can render your movie at a framerate as high as you want it to be, yet keep disk usage flat. Adds a nice motion blur effect to the video. Also includes shutter angle simulation.

Can be used with any Source engine game with Source Recorder, which includes:

• Team Fortress 2
• Team Fortress 2 Beta
• Portal
• Portal 2
• Counter-Strike Source
• Any mod of the above games
• Future Valve titles, possibly
• Works with Left 4 Dead and Left 4 Dead 2, but those two games use a glitchy version of the Source engine, which causes severe graphical issues (zombies teleporting all over the place) when rendering at high framerates

Relies on the Dokan library.
