The word is convert with a V, not confert, which is why you probably couldn't find it in the manual. You did look in the manual I presume?
You didn't indicate which program and version that you're using. I'm guessing that it's one of the versions of PhotoStory on DVD. Correct? Magix has more than a dozen different programs.
You don't convert, you export. Look up Export in the manual to understand how to do it. There is a button at the top of PhotoStory 2013 that says Export. You probably also have this, but read the section in the Manual first. I suggest that you also read the Introduction and Quick Start before going any further. You definitely need to know what an MPH file is as well.
