Easy-to-use software and apps have made video creation achievable and affordable for many library and information professionals. While there are parallels between delivering library training in-person and via a pre-recorded video, video creation does present additional challenges as well as exciting opportunities. This paper, by Charlie Brampton, uses Clark and Mayer's model of cognitive processing as a framework, and explores how video watching can lead to extraneous, essential and generative processing. These three concepts are explored individually, and practical advice is given about controlling each type of processing. The related topic of video accessibility is discussed, from both a legal and a practical perspective.
