Insert a video from another site (Office 365)
In PowerPoint for the web, you can insert an online video from YouTube or Vimeo on a slide. (If you have an Office 365 business or education subscription, you can also insert an online video from Microsoft Stream.)
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 in order for the video to play successfully.
*Internet connection is required*
Click on the Insert Tab
Go to Video
Click on “Online Video”.
In the YouTube search box type the video name, or keyword; if you don’t have a title click on search and find video.
Find video and click Insert.
*The other way to do this is just the other way around*
Go to Youtube and find desired video.
Click on Share.
Click Embed.
Copy the highlighted code.
Go back to PowerPoint and make sure the destination slide is displayed.
Click the Insert Tab.
Expand the Video menu box.
Select Online Video.
Right click and “Paste” the YouTube Embed code in the “From a Video Embed Code”.
Click the Insert Arrow.
