In your web browser, locate the video you want.
Copy the URL of the web page from the Address bar of your browser. (This is the bar at the very top)
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.
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.
