Is it possible to upload videos from screencast.com (Camtasia files?)

Hi there, can you please help. Is it possible to upload videos from screencast.com (Camtasia files?). If so, can I just use their embed file or url - if so, how do I do that. I tried inserting both the url and the embed code (2 separate attempts, of course!) but nothing shows up. Or do I need to use the SCORM option for producing the file? Many thanks. Angela
