We encourage all speakers to use the OSA background when presenting—either live or in a prerecorded video.

The Zoom platform allows you to customize your virtual background in Settings/Virtual Background.

Note that virtual backgrounds work best when you present in front of a bare wall with no bright light behind you.

Use the Zoom Practice Room to rehearse, including sharing your screen, giving your presentation, advancing your slides and testing your mic and speakers for optimum participation during the meeting.
