If you ever recorded a lecture in Camtasia (or any other app), chances are that you faced a dilemma when saving the recorded file. Since lectures tend to be typically long (45 min or more), the resulting file (mov, mp4) end up often being too big. This can be a problem, especially if the goal is to upload the lecture to the cloud (Box, Canvas, YouTube, etc.).
A reasonable solution is to split the lecture into parts and save each part as a separate file, then upload each file separately to the cloud.
