There's less clutter and interference in the written word. It's just a dialogue between two people. One of them talks from his life experiences, like a grandpa, the other one listens, ask questions, wonders, like a little kid who doesn't know anything about life. What does a video add to this dialogue? Only clutter, in my opinion. If it's a word for word reading of the original, then that definitely adds some value, but then you'd call that audio and not video. So I assume by video you mean moving images, and sound and tone and interpretation and change of pace and interruptions and "I'm waiting to be inspired moments" from you and "Here's a video with dramatic music on top of it. Are you amazed?" from the video producer. Adding splash doesn't mean the producer knows what he's talking about. Often times it's just a way of hiding the lack of understanding. For a comparison, a good website doesn't need anything besides black text on a white background. A website that doesn't have anything to say will have to compensate with flashy tricks and will make you unaware of the fact that it has nothing of value to deliver.

You don't need any production values - just a recording of a great lecture. For me, it was easier to grasp basic linear algebra concepts from G. Strang's video lectures than from his textbooks. That is because, in a lecture, you get the text content plus intonation/pauses/stresses/all other nonverbal stuff, plus drawing on blackboard [1], plus physically pointing to various elements of equations etc. In text, all that nonverbal stuff needs to be expressed in a text format (plus illustrations), which is a narrower channel and thus often the content gets technical, awkward and hard to parse. Studying math is perhaps the best example of this - if you have some basic math literacy, someone can convey a new math concept to you in a short conversation, while parsing out the intuition of the same concept from the textbook could possibly take you a couple of hours. [1] In the textbook, you only get the final illustrations, while in lecture you can see him drawing them, and the specific way he does it conveys information in itself.
