Unless it's for something physical (assembling an object) or otherwise visual (painting, 3D computer modelling, mapmaking), video tutorials are pretty bad for conveying information, due to low information density. For programming, it is especially wasteful, as compared to an article with code samples, or, if necessary for the particular topic, a screenshot or two.
