Case studies aren’t the most entertaining or engrossing things to read. Even if a case study directly involves you yourself, or your own product or business, it’s slow, hard work going through all the descriptions and discussions of the background, methodology, data, and analysis of the case. And when you put a case study out there for other people to read, in order to make an impression or drive certain points home, imagine how much more difficult it is for the audience to be drawn in. Many people will simply skim through the entire thing, in which case they’re probably missing a lot of what you really want them to see, and you and your case study aren’t making much of an impression.
Presenting your case study through a video, on the other hand, makes for a richer, more compelling experience. In a sense, it is of course only a summary – you can’t put your entire case study and all your data into a video – but unlike a text summary, a video isn’t necessarily superficial. With a video, you can dip in and out, zoom into particulars that you want to highlight, then zoom out and take a broader view, provide some analysis and conclusions, all in the space of a few minutes.
