Similar to how you position or reposition pictures and shapes, you can make changes to any inserted video in PowerPoint 2013. In addition, there are some very basic video editing options that can be significant. These include how you resize, rotate, and flip your inserted video clips.

Flip, the last of these options though is something you will almost never use — unless you want to do something drastically different!
