I’ve prepared videos of tutorials I did in almost real time, and though all of it was done to a very amateurish standard, I still spent about 2× to 3× of the time of the (2-hour) tutorial working on that. No transcripts, not even a list of chapters or landmarks, just gluing the 30-minute videos from my camera together (have I mentioned I hate the tax code?), fixing superficial fumbles (white balance when the session straddled the sunset, mild overexposure, etc.), and preparing an erratum. Unless there are professionals who’ll do it for you, these things take more effort than you expect. (And even then there still has to be someone who can deal with the subject matter.)
