Office Mix (Customer Preview)
Turn your PowerPoint presentation into an interactive online lesson. We call this a mix. Everything you need to create and share your mix is included. Add audio and video of yourself giving your presentation, write on slides as you talk to them, insert quizzes, practice exercises, and more – all from within PowerPoint. It’s like a screencast, but better. All you need is Office 2013 and the free Office Mix add-in.
