When you’re doing a tutorial or game session, and you want the audience to see your expressions, CS can help with that. Use the picture-in-picture mode to create a video showing your instructions on screen. Another cool thing when using this is that Camtasia can split the recorded file into two separate tracks. One for your talking head and one is the actual content. You can edit each of them as an entire project.
Camtasia Studio is a comprehensive program for creating instructional or other videos using screen capture. The interface is accessible to all users at all levels, from novice on up, and the finished product you can create with this app will have a truly professional feel. You can test out Camtasia Studio for free for 30 days. After that the full purchase price is $299.
