Once you insert a video in your slide, you can crop it in almost the same way you crop a picture. Before you crop though, you must ascertain whether PowerPoint’s Crop option will help create a better result for your inserted video. The Crop option allows you to remove not-required areas of a video — for example, if the subject of your video is a person speaking who is surrounded by a large, distracting background of other people or moving objects, you may want to crop the video so that the cropped video now focuses more on the speaker, and gets rid of all the extra distractions. Note that cropping a video does not trim the timings of the video playback in any way – in fact trimming is a completely different option that will be explored in another tutorial. In the following tutorial, we will explore how you can crop a video clip.
