Saving your presentation as a video
If you plan to make your presentation available to others online so that they can go through it on their own time, you can save your presentation as a video others can view. This makes it possible for others to view the presentation without needing to have PowerPoint installed on their system or device.
Create a video
Save all changes in your presentation and tap File to display the Backstage view.
Tap the Export tab.
Choose Create A Video.
The Create A Video pane appears on the right side of the Backstage view.
Tap to choose the format for the video.
You can select Computer & HD Displays, which saves the file so that it can be viewed on a computer or other high-definition displays; Internet & DVD, which saves the presentation in a form suitable for the web or a standard DVD; or Portable Devices, which saves the presentation in a form optimized for devices running Microsoft Zune.
Tap to choose whether you want to use the timings and narrations you’ve included with the presentation.
If you opt not to use the timings saved with the presentation, you can specify the amount of time that you want to assign to the display of each slide. If you are prompted to provide your logon information, do so at the prompt.
Tap Create Video.
PowerPoint displays the Save As dialog box, in which you can choose the folder where you want to store the video.
Choose the folder for the video.
Enter a new name for the file, if necessary.
PowerPoint saves the video to the folder you selected.
