I'm not a fan of video for learning things - it's too slow and it's very hard to go back and find something later when you want to review some step. I'd much rather have still pictures and text.
While some presenters are direct and to the point, some wander around so much that you get irritated waiting for them to say and do something worth while. It's hard to fast forward in those situations because you don't know where they're going to say something valuable. I think video encourages people to blather. With text, someone (an editor) usually reads the text prior to publication and edits it to remove the extraneous material.
