You just need the URL for the Prezi presentation you want to show. Log into your Prezi account and load the presentation. Click the Share button under the presentation and copy the URL. Now open your PowerPoint presentation and go to the slide you want to show the video on. We suggest creating a new slide for the web page. Go to the INSERT Tab and click on Insert Web Page. Paste the URL, click the check box to Enable web page browsing and click OK. When you run the presentation slideshow, your Prezi presentation will load instantly when you get to this slide.
