Hey KurtDon't worry about glitches.
I interview people every week and screw things up regularly.
I just edit the screw-ups, both mine and the interviewee's, and sell the edited audios for loadsa $$$.
As I believe the Nike ad goes just 'Do It'
The information you have at your fingertips is so valuable, that I think every member of this forum would excuse any 'hiccups' that you may have when recording your informative videos.
They don't have to be 'perfect', to convey the information.
Just legible enough to understand the concept/method/strategy and put it into practice.
So far I have never had any difficulty following any of the videos that you have produced.
If you want any help with either video or audio production/editing let me know.
HTH
Kind regards
Ian
