Learned
Keep it short
Be authentic
USB headsets
Keep it simple
Record short segments to that when mistakes are found the entire lecture does not need to be re-recorded
Slips of the tongue and mistakes in the lecture should remain.  It gives the videos a level of authenticity and helps students see how to catch their own mistakes.
USB microphones are preferred over analog because much of the noise is filtered out during the digitization before the data enters the computer.
To minimize video size, avoid live action video or smooth transitions.
