How can you change the video playback settings in a presentation?

1. Choose Relevant Videos: The video background should be relevant to the topic of your presentation. It should enhance the message, not distract from it.

2. Keep It Subtle: The video should not be too flashy or fast-paced. It should be slow and subtle so it doesn't distract the audience from the content of the presentation.

3. Use High-Quality Videos: The video should be of high quality. A low-quality video can make your presentation look unprofessional.

4. Test Before Presenting: Always test the video in the presentation mode to ensure it plays correctly.

5. Use Videos Sparingly: Don't overuse videos. They should enhance your presentation, not take it over.

To download and insert a video in a presentation, first, open the presentation you want to use or start a new one. Then, choose a design theme for the presentation.
