Not all the time. At least when it comes to subjects involving physical things as opposed to software or theoretical subjects, video greatly expands the amount of raw information captured at the expense of total density. It takes quite a bit of control out of the author's hands, so to speak, by capturing far more than the words they explicitly choose to write. When it comes to fixing or building things, for example, this means that video has the potential to capture a lot more incidental information that the author might never think to include like the speed and strength of movements as well as tactile responses that are nearly impossible to describe in a consistent manner. I think text is better when you already know what you're looking for and video is better when you are still trying to develop an intuition for the subject.
