Before investing a lot of time and money in designing a video to complement your presentation, take a step back and think why you want it, then brief the designer accordingly. Some uses of video are more useful than others:
- A spectacular, wow, stunning, noisy, beat drumming, flying effects filled, splash opening that leaves the audience shuddering in their chairs
- Customer testimonials and/or other interviews of people that are hard to bring to the presentation room
- An explanation/demonstration to show how your product works, is used in practice
- A high-paced, scripted story
- A funny, cute cartoon to support your message
- A complex animation that is hard to execute in PowerPoint or Keynote
- A narrated slide sequence that you can send to people you being present to explain it
