It's interesting that you say videoing a lesson can make you nervous because you're trying to get it as perfect as possible. I get nervous when I video myself too because I always anticipate that it's going to require quite a few takes before I get a video that I can accept, and then I start psyching myself out, especially when I get close to the end and I haven't made any unacceptable mistakes yet, then the inevitable alway happens, I mess it up right at the last couple of measures. It's reassuring to know that even the most professional, talented musicians get a little nervous too under pressure.
