When you've made all your selections, choose Export. You can also choose to set the amount of time the video will spend on each slide if you don't have a set timing. If you have recorded timings and want to use them in the video you create from your presentation, make sure the box next to Use Recorded Timings and Narrations is checked.
The higher the video quality, the larger the file size. Select the video quality you want: Presentation Quality, Internet Quality, or Low Quality. On the File Format menu, select the video format that you want (MP4 or MOV). If you have an Office 365 subscription, make sure you have the latest version of Office. Note: This feature is only available to Office 365 subscribers.
If you want to send your presentation to someone but they don't have PowerPoint for Mac or PowerPoint for Windows, you can export your presentation in a different format, such as a picture format or a PDF file, so the recipient can view the slides.
