Video and audio data and the lecture slides are recorded by this software.
Video and audio data and the lecture slides are recorded locally using the recorder software.
Instead of using the external Epiphan frame grabber, you can record your own desktop as a screencast.
First choose an ideal resolution of the display you want to record (go to System Preferences -> Displays). We recommend a resolution of 800 x 600 or 1024 x 768. Higher resolutions will result in a reduced frame rate and blurry pictures because of downscaling.
