1. Before recording a screencast, plan ahead by creating a storyboard and script if needed. Also open any files and windows you will need and tidy your desktop to avoid distractions.
2. During recording, practice first to work out any kinks. Speak naturally and use gestures like the mouse cursor to draw attention to parts of the screen.
3. After recording, don't over-edit as it can make the video seem artificial. Watch it through before sharing and save and name the file in a logical way depending on your intended audience.
