Thanks for doing this, David! Although there are a lot of nice-to-haves in terms of updating and otherwise improving the tutorial, and hopefully some of these will happen, even without them I think this would be better than nothing.
As for editing video, sorry to hear it isn't as easy as one would think. I note that the internet is full of questions like "Is there any video editing software that combines the functionality of Audacity w/ video?" Sound quality is another nice-to-have in terms of experimenting with microphones, software and even the room where one records, but at least for me it was "good enough" in the sense of not being distracting.
