Hi Alan

I've only made basic videos using Camtasia and I found the best way was just to watch the 3 or 4 basic training videos then dive in and play around.

I wasn't too sure about the editing at first but after a bit of practice I found it superb. You can turn a video with loads of ums and errs into a slick running masterpiece (slight exagerration there!).

I've not needed to make any videos using transitions and other features yet but along with the provided training videos, I'm pretty sure it will be very simple after a bit of trial and error.

Good luck.

Alan
