> Record Everything at Once
> Using this method, you record each recording source in a single session—simultaneously recording the display, camera video, microphone audio, and computer audio. When you are done recording, you can use the editing tools to finalize your screencast project.
> For example, you might start a screencast project by recording your display, then cut to a Picture-in-Picture of a camera recording, as you demonstrate the application. Later, you fade out your video, leaving only the audio to narrate the remaining moments of the screencast.
> This method is considered a single-pass production. It works well when your subject matter is simple, straightforward, or short. For longer or more complex screencast projects, you may find the second approach more comfortable.
