What, you playback your videos, and then record with fraps?
Source has a built-in video renderer.
When you're in a menu, type this in console
startmovie [moviename] [video type] [FPS]
So an example would be
startmovie myvideo avi 30
Once the console is cleared, play your demo. It will start rendering it into an .avi from the start and end of the demo.
If you know how to mess with the demo playback, you can choose your starting point and the end point.
Heres an example,
Filmed on a 6-year-old laptop 17FPS with lowest settings,
Rendered at 30FPS with Max settings + motion blur and simple DoF.
