PowerPoint versions 2010 through 2016 for PC make it extremely easy to record a slideshow with narration and save to video without any additional software. Narrated PowerPoints can be exported to video to post on YouTube or Canvas. Please note that there are differences among PowerPoint versions: PowerPoint 2010, 2013, and 2016 for PC provide the option for direct narration to video, whereas older versions and PowerPoint for Mac do not.
