I need to use Camtasia at work. I looked for an instruction book, and found that this is really the only choice available. Fortunately, Daniel Park did a great job writing it. It covers the program in great detail. It's written in a very conversational style. For example, these lines are taken from page 19 and 20:
"And here's another blow to the prescriptivists: Whether doing stand-up technical trainings or writing documentation, I generally find it preferable to address the learner in an informal, conversational tone. In this book (and in other manuals I've constructed), I tend to write like I talk, which I believe makes the text a lot more approachable. But it also means that I freely start sentences with conjunctions, end them with prepositions, and occasionally make use of puns and other corny humor that some may find off-putting. If these sorts of things bother you, then you are more than welcome to go write your own book. . ."
Although I have not yet read the entire book from cover to cover, I've read enough to know that he obviously understands the program very well, and he is a talented enough writer to be able to entertainingly share his information with the reader.
