How do you format the video on slide 3 to play full screen?

To format a video on slide 3 to play full screen, follow these steps:

1. In Normal view within your presentation software (e.g., PowerPoint), select the video frame on slide 3.
2. Go to the Video Tools contextual tab. This tab usually appears when you click on a video. If you don't see it, ensure the video is selected.
3. Within the Video Tools, navigate to the Playback tab.
4. In the Video Options group on the Playback tab, find and select the "Play Full Screen" check box.

By selecting the "Play Full Screen" option, the video will automatically expand to fill the entire screen when the slide is presented in slide show mode.
