Someone or the other I was reading recently said that some people learn better from video tutorials than screenshot and text and some don't. So he/she produces both and was being pleased about a piece of software that made that easier.
Actually, I don't mind overview tutorials in video.
Most of us have a dominant style (I am quite strongly kinaesthetic), though we have elements of all three, and that mixture varies according to subject. But a well-planned lesson/training session (for children or adults) should, according to current theory, include elements of all three learning styles in order to play to every learner's strengths.
