Watch this short demonstration from Xavier's Digital Media Lab on how we recommend you capture a PowerPoint presentation that includes animations or embedded video clips along with your voice.
As you create your content, make sure to leave room at the bottom of your video for the captions. To meet ADA requirements, the captions cannot overlay other text or crucial visual information.
One of the Digital Media Lab's Faculty Video Content PowerPoint Templates can be used to help you make sure the appropriate amount of room is left at the bottom.
