Camtasia (Windows) 9 and Camtasia (Mac) 3 and Later
Camtasia (Windows) and Camtasia (Mac) now save their projects in .tscproj format. This allows projects created in Camtasia (Windows) 9 and Camtasia (Mac) 3 to be transferred back and forth.
However, not all media files and effects work across platforms. Additional legacy callouts and captions are not cross platform compatible. For information on cross platform projects please see this article.
