The explainer video is a very important marketing tool. Increasingly popular and increasingly desired by manufacturers and brands. Above all, the explainer is a kind of complement to an advertisement or promotional video. It allows us to learn not only about the features of the product and its advantages, but also about its use and functions. It is a much more modern and illustrative version of the paper manual. It has been well known for a long time that we absorb knowledge much more easily and quickly when a picture is involved. This is exactly the case with the manual. The instructional video, by the way, has a promotional and advertising function. By conveying information in a multidimensional way, it comes naturally that by explaining how a product works, we immediately promote it.
