According to the Videoscribe you can "Share to Facebook and YouTube" and "Share to PowerPoint"
However, whenever I try to export, it does not work. It simply has a blank screen and says "preparing video information", but never actually exports to facebook, youtube or powerpoint.
That problem usually indicates a problem with your scribe.
You could save your scribe with a new name, restart videoscribe and try again,
or you could save your scribe online and tell support the name of it if you want them to have a look at it.
