 What is the difference between Alternative Host and Co-Host?


Allows someone else to manage the administrative side of the meeting, such as muting participants or starting/stopping the recording.

 Sharing a Multimedia Video with Audio

Yes, you can share a video clip with sound on your desktop to other participants.
  1. Click Share Screen.
  2. Select "Share computer sound" and "Optimize for full-screen video clip"
  3. Click Share.


Our colleagues in NUS have shared that it plays better for participants when:

  • It is a local MP4 file in the computer
  • Video is playing on a dedicated Video Player like VLC or QuickTime
  • Video is played in full screen
  • Optimize Screen Share for Video Clip is selected

Playing a video embedded in a powerpoint slide or playing on a website like YouTube, doesn't seem as smooth in comparison.
If you have to play a video from YouTube, try playing it at a lower quality.

Manual Breakout Room Tip

For easier manual Breakout Room grouping, you may want to ask students to rename themselves with their group names at the front.
Example: Gp1_Adam, T1-Adam or 1-Adam.

 There is Echo...

Sometimes you will hear audio echo or audio feedback during your meeting. For bigger groups, it is advisable to select "Mute Participants on Entry". For even larger groups, you may want to prevent students from unmuting themselves.

To solve the Echo issues:

1) Isolate the participant
As a host, if it is a small group, you can do a Mute All and unmute individually to find the source. You might not have a time to do this in a big group. Do a Mute All and let them know to unmute only when given permission to talk.

2) Cause of Echo

  • Participants not joining using headsets and joining using external speakers. So what happens is the built-in mic picks up audio from the external speakers causing echo from other.
    Unfortunately, in most cases the one causing echo will not hear the echo.
  • Two or more participants with active audio joining from the same room (physically). If that is the case, only one device should Join Audio. All other devices should Leave Audio.


 Speakerphone Devices

It is not possible to have 10 member is the board room to share the mic from a single laptop.

While there are products meant for bigger rooms like the Logitech available for purchase, there are existing equipment that your office may already have.
Most offices in NUS will have the the Polycom Trio used for boardroom telephone calls. That Polycom Trio can also be connected to a laptop; either Bluetooth or USB.


Use a Micro USB cable to connect the 
Polycom Trio with the laptop.
Select the Polycom's Speaker and Microphone device in Zoom.
Run the Test Speaker and Microphone to configure it.

 Breakout Rooms

Breakout rooms allow you to split your students into their discussion groups. The Host can split them automatically or manually.
  • Host can split them automatically or manually.
  • There can be up to 50 Breakout Rooms per meeting, maximum of 200 per room
  • Breakout Room participants have full audio, video and screen share capabilities
  • Hosts can move between Breakout Rooms
  • While in a Breakout Room, participants can request help from a host

    Improve student engagement with breakout room flexibility

    Coming in September, students will have the ability to select a breakout room and move between rooms. This allows even greater flexibility in the way you structure your small group learning. You can create themed breakout rooms or reading groups and invite students to move between them based on their interests in topics. The possibilities are endless, so get creative!
