When I save a video ti is in Camtesias format. How can I share it with others?
If you use the Save project command, Camtasia will save your work only as a .camproj file, which can only be opened in Camtasia. When you have completed your project, use the Produce and share command. The Production Wizard will then give you a number of file format options (mp4, MOV, WMV, etc.) to share your work.
