Here’s a series of tutorials on video editing with Camtasia. If you’re in a hurry, make sure you at least watch Part 1 (managing your assets and files) and skip down to Part 7 (where I edit a short video from the start).
Part 2: Explores the Camtasia editing workspace.
Part 3: Outlines the two methods for recording your narration.
Part 4: Details recording just your narration without any video.
Part 5: Explains how to record your narration along with your slideshow at the same time.
