next week I have to make webinar for my patients/ theirs parents with facebook (live). I would like to use prezi pesentation, so I have installed prezi video and I have imported prezi next presentation. Everything works great, but there is one problem. There is no sound during presenting movies from my presentation, which include recorded movie - an interview. I can see videos without any sound… There has to be sound during presentation from movies included in prezi presentation path.
