What technology do you use to record your courses?
The tech we use keeps changing, but here are the basics.
Skype - to connect the guest with the course leader
CamTwist - to switch between shots (Andrew, his guest, web pages, etc)
Ecamm Call Recorder - to record.
ScreenFlow - to edit
Explaining how it all fits together is TOUGH, but if you install CamTwist and play around with it, you'll get the idea.
