Oftentimes, a short video is the only way you can trick someone to understand the point you are trying to convey. However, videos take both time and talent to produce.
A few months ago, we had a similar problem. I was working with a few folks from The Melton Foundation to popularize a grant that enabled it's fellows to do travel-related projects. We had received feedback that the marketing for this project had been very poor.
So, over the course of half a day, Anirudh and I came up with this stop-motion video - I drew and he shot the frames. It's crude in a lot of ways, but it was so much better than sending copy in a newsletter that people are likely to miss.
