Insert a video from or another site (New Versions)
In PowerPoint for Office 365 or PowerPoint 2019, you can insert an online video from YouTube or Vimeo on a slide.
The video plays directly from the website, and it has the site's controls for playing, pausing, volume, and so on. The PowerPoint playback features (Fade, Bookmark, Trim, and so on) don't apply to online videos.
Because the video is stored on a web site, rather than in your presentation, you must be connected to the internet for the video to play successfully.
Insert a video from a website
Insert a web
In your web browser, locate the video you want.
Copy the URL of the web page from the Address bar of your browser.
Switch back to PowerPoint and select the slide where you want to place the video.
On the Insert tab of the ribbon, select Video > Online Video.
In the Online Video dialog box, paste the URL you copied in step 2.
Select Insert.
Play the video
If a video is inserted successfully, you can play it either in Normal view or Slide Show.
A Play button appears on the video in Normal view.
In Slide Show, you can interact with videos just as you would in a web browser.
By default, videos from YouTube and Vimeo play in "click sequence." You can play the video without having to click the Play button. Just tap the spacebar to advance to the next step in your click sequence.
Troubleshooting
Not all online videos from these sites can be embedded. You should check on the video site to find out if a certain video can be embedded.
