Although Camtasia is significantly better than iMovie (which has turned into junk over the years) it is still lacking and limited in features on the Mac. I use Camtasia at work on my Windows based workstation and it is great, full of features and easy to use. On the Mac the features are either missing, hard to use, or just clunky. I also found that exports from my work computer are not usable in the Mac version and vise a versa; that is shame. If you need more control and editing features than iMovie provides and do not need the power or the learning time for Final Cut then this will work for you. It is just depressing that such a limited version of software (as compared to the Windows version) is so pricey. It is hard to accept paying $99 for stripped down clunky software if you have experienced the better Windows based version (and that is hard to say, being an avid Mac fanatic / Windows hater).
