Camtasia Studio QuickStart Guide for Authors, Part 1: Getting Started with Screen-Capture Video Production
Narrating and Annotating Screen Captures
Begin by mapping out a series of segments that tell your "story" effectively, and then practice the steps you want to demonstrate or teach. When the recorder starts, you need to know what you will show and what you will say. As mentioned earlier, many errors can be corrected in the editing stage, but the more problems you've anticipated up front, the better.
You can open Camtasia Recorder directly from the Start menu, or from a button within Camtasia Studio (see Figure 1).
