Content: Select your video
Navigate to the Video Format tab
Open the Poster Frame drop down
Select Reset
Selecting Reset, whatever Poster Frame you set for your video is removed. Doing so, PowerPoint once again uses the default Poster Frame for your video (its first frame). After resetting your Poster Frame, you can always add a new one as discussed above. How to make a video play full screen
If you embedded a video from your computer into PowerPoint, you can get it to play full screen without having to resize it. If you are working with an online video in your presentation, see the note down below about Getting an online video to play full screen. To make a video Play Full Screen in PowerPoint (regardless of its size on your slide), simply: Select the video on your slide
Navigate to the Playback tab
Click Play Full Screen
Now whenever you play that video inside your presentation, the video will play in full screen, regardless of how you resize it on your slide. The cool thing about this Play Full Screen feature is, you can then design your slide any way you like with your videos, and have them play full screen when you click them. For example, you could put 3 instructional videos on the same slide, and have each one play in full screen when you click it. Getting an online video to play full screen
Because the Play Full Screen command is not available for online videos in PowerPoint, online videos will play in whatever frame size they exist in on your slide.
