Virtual backgrounds and background blurring are features of Microsoft Flip that can be helpful to you and your students in a few ways. First, virtual backgrounds and blurring are useful in protecting student privacy when they are recording at home or anywhere else outside of your classroom. Second, you can use virtual backgrounds as a teaching aid (see my video below for more about that). Third, virtual backgrounds are just fun and provide a nice way for you and your students to express a little personality.
In the brief video that is embedded below I demonstrate how to use virtual backgrounds and how to blur backgrounds in Microsoft Flip videos.
