By doing so, a presenter demonstrates to the audience that he is unprepared and/or unfamiliar with the basic operations of audiovisual equipment. It’s boring to watch someone fumble with equipment onstage. One of the readers of this blog told me about a pet peeve of his: What I hate most is having to wait for someone who desperately is looking for a movie on YouTube, using “Alt/Tab” all the time and finishing with “Sorry, can’t find it.” It happens all the time! Whether it’s to explain difficult concepts, provide an entertaining and informative break, or demonstrate processes, videos are a great way to add content and variety to a PowerPoint presentation.
