I was hoping you guys know a good program to record video games on OS X. More specifically, Source engine games (from Valve) such as Half Life 2, Team Fortress 2, etc. I have tried Screenflow, but the game performance is pretty affected by it. The game stutters pretty noticeable. (Here is an example: http://www.youtube.com/watch?v=POVb-huB47E . If you look very closely you can notice the stuttering and lag.) Also Screenflow lacks export movie customization. I need to get at least 5mbits/s at 640x360 export resolution and there's no way to do that as far as I know. The only option I can use to export videos for use in iMovie is Lossless. But my last video, 35 minutes long, was 60GB! Plus, iMovie converts the video again for editing, so it takes even more time until I get to editing. So any suggestions for a game recording software for Mac OS X? Thanks a bunch!
