Using this method, you first record the display (optionally, without computer audio), demonstrating your application or subject matter without any video or voice-over.When you have finished your demonstration, you can record your camera and microphone sources while playing the video preview of your demonstration in ScreenFlow. This can be done in a single long recording or several short recordings.You can then edit your recordings to align your narration with your demonstration or fade your camera recording in and out when appropriate.This workflow is effective when the screencast involves a series of complex mouse or keyboard operations, or you have several comprehensive steps or tasks to achieve, each of which take some effort to produce.
