Tips for making a screencapture video ( I use camtasia, $149 educational prices):

1. 1. Record the audio in segments so that you don't have to make it through in 1 shot.
2. 2. record the audio first.  Then have it playing back as you record your actions.  Make sure to remove the 3 second dead-time between audio tracks. In window media player, this is called cross-fading
3. 3. Lower the mouse sensitivity.
4. 4. Make yourself numbered notes of the keypresses and mouse actions you'll have to make.
5. Use a handheld microphone to record the voice, and move it away from your mouth whenever you take a breath.
