There are many reasons why someone might want to create a screencast to give/show directions. It is not an easy task if you don’t know what to say or how to navigate through your computer to show the user where to go during your screencast. A great way to help your screencast become professional and well received is to create a storyboard. A storyboard maps out scene by scene (screen by screen) and also lets you take notes and write down a script of what to say when. This will help you be more prepared before you begin recording your screencast.
Here is an example of a storyboard of how to make an egg.
