Cropping a Video in PowerPoint is similar to how we crop photos in other Microsoft suite programs, with a few key differences.
How to Crop a Video in PowerPoint
Step 1 - In PowerPoint, select the video you want to edit by clicking the added Video in your slideshow.
Step 2 - In the tabs section, select Video Format then Crop.
Step 3 - On the video, you will notice small clamps holding in all four sides of your video. Select one of them, and crop the video to fit your need. Keep doing this from all sides until you have the video size you want.
Step 4 - Click on the Crop option when you are finished, and you have successfully cropped your video!
