3. (Optional) Enable these features:
   1. Check Share Computer Sound to any sound played by your computer shared in the meeting.
   2. Check Optimize for full-screen video clip if you will be sharing a video in full-screen mode. Do not check this otherwise, as it could make the shared screen blurry.

Sharing a Pre-Recorded Video

Zoom allows participants to share video with audio to participants. 

1. Click Share in the meeting controls.
   
   
2. Select the video from the available screens. We suggest having the video open in a separate tab, to make it easier to find.
   
   
3. Select Optimize for Full-Screen Video Clip from the bottom of the "Share" window. This should automatically select Share Computer Sound as well. If it doesn't, select that option as well.
   
   
4. Click Share.
   
   

Sharing a PowerPoint

By default, your PowerPoint presentation will take up your whole screen, hiding the "Chat" and "Manage Participants" controls. Follow these instructions to contain your presentation in a browser window, rather than on a full screen.

1. Open the PowerPoint you want to present.
   
   
2. Click Slide Show in the top menu toolbar, then click Set Up Slide Show.
   
   
   
   
3. Under "Show type," select Browsed by an individual (window) and click OK.
   
   
   
   
4. Open your presentation by opening the "Slide Show" tab, then click Play from Start or Play from Current Slide.
   
   
   Your presentation will display in a window.
   
   
   
   
5. Start or join the Zoom meeting you are presenting in. 
6. Click Share Screen in the meeting controls.
7. Select the PowerPoint window and click Share.
