Before you actually dig into the writing of a video script, you should sum up the objective of the video in a single sentence. You should also have the client review it so you're both on the same page (no pun intended) as to what is the goal of the video.
Example: "This video will explain to XYZ Company's support staff about changes to the warranty coverage for the Elite series of widgets."
Write the objective on a piece of paper or index card, and post it near you computer when working on the script. After you've done product research, interviewed employees or customers, written down your ideas, it can all seem a bit overwhelming, and you can easily lose the main purpose of the video script. A script outline or treatment can help clarify key points but having something short and succinct like a single sentence objective can go a long way to keeping your script on track.
