The good thing about Camtasia is that the free version contains every function of the original one. So, you can try all the game-changing features such as the overlapping media. It’s an inherent mechanic that lets you combine multiple clips into one video. Other programs, such as OBS Studio or Filmora Video Editor, can do the same thing, but not as easily as CS.
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.
