I need to be able to give a 3 minute overview of our business model to prospective clients, as a video. It needs to be very professional and slick, and explain a few difficult concepts. It needs a voiceover and needs to show different slides.
What's the best way of building such a video? Does anyone here have any experience doing this? Is it best just to use Flash to create one from scratch, or is it best to export something from Powerpoint and then somehow add in a voiceover?
I've never done anything like this before so any information would be greatly appreciated
Many thanks for your help
