1, on the Slides tab, in Normal view, click the slide you want to add the video to.
2. In the browser, go to the Web site that contains the video you want to link to, such as YouTube or Hulu.
3. On the website, locate the video, and then locate and copy the "embed" code.
Note: Most Web sites that contain video include embedded code, but the location of the embedded code varies depending on the site. Also, some videos are not embedded in the code and therefore cannot be linked to these videos. Another point to clarify is that although they are called "embedded code", they are actually linked to the video rather than embedding it in the presentation.
On YouTube, the "embed" code is on the right side of the video.
4. Back in PowerPoint, on the Insert tab, in the Media group, click the arrow under Video.
5, click "Video from the website".
6, in the video from the web dialog box, paste the embedded code, and then click Insert.
