Uploading to youtube

I am trying to upload my first animation to YouTube but the file is a .xstage . I was wondering if there is an easy way to convert this to a different file format. EDIT I have also tried exporting it to QuickTime Movie format from the harmony programm but when i go into QuickTime it is not there

Is this because i am in a trial version of harmony?

Can you post pics of what you do?
