Adding a video thumbnail (or what PowerPoint calls a Poster Frame) is super easy. But this is only applicable to videos you add to your presentation from your computer. That’s because online videos will automatically populate with whatever thumbnail their creator gave it (you cannot edit it or change it in PowerPoint). There are two types of thumbnails you can add to your videos in PowerPoint: Use a frame from your video as the thumbnail (easiest)
Import your own custom thumbnail image (most flexible)
Neither is better or worse (your video will still play the same either way), it’s just a personal preference. What is a video thumbnail and why is it important? A video thumbnail is simply an image that is displayed before you play your video. You will see these on YouTube videos all the time before you click to play them. In PowerPoint, the thumbnail image can become an important part of your overall slide design theme.
