Similar to Shape Styles that you apply to shapes, PowerPoint provides you with Video Styles for your inserted video clips. These pre-built Video Styles add edges, shape, and effects to videos — and can be applied with just a single click. Your videos no longer need to be rectangular — some of the Video Styles change the video clip so that it plays within an oval or a rounded rectangle. Video Styles also transform the look of your inserted videos by applying borders, 3-D effects, shadows, frames, etc. around your video clip.
