There are many ways to create a captivate project, but the most basic way to create a project is to 1) have the content you want to include in the project ready and running on your computer (i.e. powerpoint or website) and 2) begin recording.
To do this:
Open your content
Start Captivate® and select File > New > Project > Record > Application
Choose the application you would like to record from the dropdown menu, select the "Application Window" radio button, and select "OK" (remember, this is a basic way to create a recording, you can change these settings if you choose--most common monitor size is 1024 X 768)
A recording window will appear around the application you selected. You will have a variety of options. For a basic recording, select "automatic recording" by clicking on it. From here, select the audio input (microphone, if you have one), select the mode (Demonstration), and change any settings you would like. The settings area will reflect the options available with the chosen mode--you can change the mode based upon the settings you would like. When you are finished, select the red "record" button to begin.
Select "yes" to test the audio level to make sure it is working appropriately. If it is, you will get a message that says "input level ok". Select "Record" one more time and begin recording your project (if you make a mistake, remember that you are able to go back and change it later). Save your project in the appropriate area and your are finished! To view your project, go to "Preview" > "Project"
