Movie Styles work for movie clips in the same way as Shape Styles work for shapes. PowerPoint provides you with ready to use Movie Styles for your movie (video) clips which add edges, constrain your movie clip to shapes, and also add effects to your movie clip — and all of this can be applied with just a single click. Your movie clips no longer need to be rectangular — some of the Movie Styles change the movie clip so that it plays within an oval or a rounded rectangle. Movie Styles also transform the look of your inserted movie clips by applying borders, 3-D effects, shadows, frames, etc. around your movie clip.
