This question often comes up when we start discussing the first sketches of a presentation.
Videos are great, it is a studio quality recording of a presentation, you can do it over and over again until you get it perfectly right. In addition, you have more visual tools at your disposal to support your message.
Having said that, if there is no story, a flashy video is not going to change that. That is why I advise my clients to start with a regular presentation, slowly add more video-like slides to it (faster sequencing of images / shapes) and only then make the leap to video (and that can go in 2 stages, one a narrated recording of your video-like presentation slides, and two a professional animation).
