Sorry for the pile on, but I second that. I also nope out on video explanations. For me it severely hampers my ability to recall the information presented.

With text I can actually pull the image back up in my mind and look at it (it might be a little blurry, but often times I can resolve what I'm looking for). With video that ability is mostly lost. My brain just doesn't store and retrieve that information the same way, apparently. It's like text makes it mostly intact to cold storage, but the only thing in cold storage about the video is metadata.
