I love Camtasia Studio and used it the last 3 years at the college I was working for. When we were using the Screencast.com accounts, we embedded the video in our Moodle, lesson, page, book or quiz and it played well from that site with all the interactive features working. The problem was that some of the teachers ran out of bandwidth on the site and all their students weren't able to access it. When we tried to save it to other sites, such as YouTube, Kaltura, etc. it did not pull in those interactive features. We needed to have the Smart Player involved. I don't know if Moodle can be made to easily pull that player in or if you need to put it on another server to make your own video server with the Smart Player. I am including links below to the information on the TechSmith website in case some of the other more server/programer types know more about it.
