This option is needed when PowerPoint files cannot be provided in advance as required in option 2. Rather than the slides appearing in a separate window, they are mixed with camera shots in the same window. The slides are captured from the on-site projector.
Another benefit is that, since both camera and slides are in the same window, your webmaster can be provided with a simple web code that will display the webcast on your site. (Option 2 requires that the display be on our server with a link from your site).
In this option, video from one or more cameras and PowerPoint slides appear in the same window. The webcast team switches between camera shots and slides.
