We use a technique where the engine outputs screen shots that are then composited into a video with a fixed frame rate. Note: This will not give you any sound!
The console command capture_frames 1 will make the engine start outputting individual frames as screen shots to a CaptureOutput folder in your Crysis root directory. The screen shots can then be composited into a video in Premiere or with a shareware program like Jpg2Avi. The video will probably look like the game is running on steroids, because the capture process can't keep up with the game (a video made at 30 FPS from frames captured at ~10 FPS).
This is where the console variable fixed_time_step 0.03333 comes in. It will lock the update rate of the game at 30 FPS. Enter this console command before starting the capture process and set it to 0 when finished.
