There are all sorts of different ways to inform people of the various things about a company, but explainer videos tend to be some of the easiest. A lot of people retain information better when they can both see and hear it as opposed to just reading it. The real trick, however, is to keep the viewer’s attention as they watch the video. If they get bored with it then the viewer will like just leave the website and move onto something else.
Explainer videos can be made in a number of ways, but animation is starting to be a big hit with those companies wanting entertaining and informative videos that are professional. Animation is enjoyed my most people, which is not to say that the videos need to be cartoonish, but that they can convey more information without needing to worry about realistic problems. Explainer videos using live people on camera may not turn out as well as some would hope.
