With the PowerPoint recording tool, you record the narrations one slide at a time. When you finish recording all slides, you create a video that combines all content into one video file. You can focus on one slide, or one idea, at a time. This is in contrast to many other recording apps, in which you record the entire video at once.
After finishing your project, you can return to it any time and edit any slide. For example, a year after you record a lecture through PowerPoint, you might want to update content on a few of your slides. You can easily update the recording or slide content to specific slides and create a new video. Below, you'll see step-by-step instructions, as well as a video demonstration.
