I record video every week, usually it happens on the weekend. I write out video ideas, I have a separate list for this and I'm trying to understand how to explain this or that material. I usually rehearse videos two or three times before removing the video. I pronounce some words or some explanation then I come to this room - this is my "studio" and start to record videos. Usually it takes me thirty to forty minutes to make videos. I usually shoot three videos right away, usually. And now I try to shoot video in one take. Sometimes, of course, I explain the material wrong or I can't ... or I understand that I explain very difficultly then I rewrite, it helps me better sort what I say, and then I edit these videos. It takes two hours, three hours, for edits probably three videos. And that's it, I upload to youtube and you watch them.
