I know I keep apologizing for this, but these one-take slap-dash crappy quality videos are really the only way I can produce them at the moment. Having to edit them tends to take at least 4x the length of the video, not counting rendering time, and I just don't have that sort of bandwidth right now. Even a little edit like this, splitting it into 2 parts, would be prohibitive. Fortunately YouTube has a new post-upload editing feature that is pretty quick. They'll even edit in a 5 second title card if you make one for them, so I may take the time to do that in the future.
Despite my self deprecation, I hope people are finding these videos useful and enjoying them.
