When you insert a video clip within a PowerPoint slide, you’ll find it placed as a traditional rectangular shape. And while that’s exactly what most users expect, it does seem safe and conventional. However, PowerPoint 2013 does allow you to have your video playing in different shapes such as a circle or oval, or a wave, a triangle, or any of the shapes that PowerPoint includes. Just the fact that a video can be placed within a shape is no reason to forego the conventional rectangle — do remember that most other shapes may crop out important parts of your video clips.
