What is it?
Camtasia is a screen capturing and editing package.
Why would I use it?
Camtasia is best used when you need to create online presentations. In comparison to Kaltura it has more control with video and editing features. It also has a quizzing feature, although it is not integrated with the grade center. Camtasia is more complex and has a higher learning curve than Kaltura so it is only recommended if you need to create a more complex project that requires editing.
