Zoom Meeting Guide

ACM has purchased a number of Zoom licenses to assist conferences holding virtual events.  These licenses are shared among all ACM''s conferences.  

How many Zoom licenses may we request?

Each conference may request up to 5 licenses, which can be utilized as webinars OR meetings for up to 500 people.  Licenses may be requested by contacting your SIG Services Staff Liaison.  It takes ACM up to one week to process requests for Zoom accounts.   

Our conference needs more than 5 licenses.  Can ACM provide more?

If you require more than 5 licenses, ACM can purchase additional zoom licenses on behalf of your event and charge the expense to the conference budget.  

Pricing as of 1/15/2021 is as follows:

  • Each 500 participant license is $200/month
  • Each 1,000 participant license is $500/month
  • Each 3,000 participant license is $1,200/month

Should you find that you don't require a license after you order it from ACM, you will still need to cover the cost.  Please plan accordingly. 

If you find you need many licenses, you may want to consider using a virtual event platform geared towards larger audiences that offers more robust features to accommodate poster sessions, social events, sponsor interaction, etc. Platforms used or being considered by ACM conferences include:

If you plan to use a platform, please notify your SIG Staff Liaison so they can assist you with contracting.  

How long may we use the licenses?

All licenses, including those charged to the conference, are available up to 2 weeks prior to and 3 days following the conference.  If you require the licenses for a longer time period, please contact your SIG Services Staff Liaison to discuss options. 

Please remember these are shared licenses and should only be requested based on the time period as outlined above. Returning them to ACM promptly after the event will help other conference organizers.

What happens to our conference recordings after the event is over?

It is the responsibility of the conference organizers to download their conference content immediately following the conference.  A way to save time is by downloading after the end of each session.  Guidance on how to do this can be found below. The accounts are reset upon return to ACM and we do not save the recordings.

  • Click the name of the meeting you would like to convert to a webinar

Recording Conference Sessions

Zoom has the ability to record conference sessions directly to Zoom for download. Please see the following section in the Zoom Help Center for instructions: 

**Important to note: ACM Zoom accounts are shared accounts. Once your conference has concluded the account is reset for another conference to use. Therefore, it is important to download any recorded material immediately following the conference, preferably at the end of each session if possible.  The files download quickly and no rendering is needed. Another option is to record directly to a desktop computer while the sessions are taking place. Please see local recording in the Zoom Help Center for these instructions.


Zoom has transcription services built into these accounts.  The meeting host has the option to turn the service on or off in each account.  For more information on Zoom transcription, please see Zoom Support.  

General Tips

  • Make sure to use the latest version of Zoom, minimum version should be Zoom 5.0.
  • Recording:
  1. Decide about recording ahead of time.
  2. Inform all those involved that it will be recorded and “enable the recording disclaimer.” 
  • Suggested Options:
  1. Meeting ID: generate automatically (avoid using a personal meeting ID other than for personal, on-the-fly use.)
  2. Require password.
  3. Video, off by default.
  4. Audio, allow for telephone and computer.
  5. Enable join before host (only allow for less formal and recurring meetings).
  • Suggested Behaviors:
  1. Hosts should click “manage participants” to keep the participant screen open.
  2. Hosts can mute and stop video for people.
  3. Hosts can remove someone for abuse.
  4. Hosts can “spotlight” a person, (make them the focus of the room, “larger image”).
  5. As the Host, spotlight yourself to start the meeting.
  6. Hosts should click “chat” to also keep the chat screen open.
  7. Chat can be sent to “everyone” or to individuals.
  8. Chat log can be saved, click on “more” in chat screen and click “save”. You can do that along the way or at the end.
  9. Your View - all users can toggle their view using the options in the top right corner.
  10. Speaker View - focuses on the active/talking user.

  13. Polls, (meetings and webinars), can be set up ahead of time or in advance. Polls can be timed. You can download poll reports. You can share with a group anonymously.
  14. Screen share – share a particular window or the entire desktop. In most cases you will want to share a particular window. Only when appropriate, “share computer sound” can be checked during the screen share process.
  15. Hide floating controls during screen share, in “more (…) “, hit ESC to get them back.
  16. Pause screen sharing, this is a great way to keep the screen up for everyone while you look something up.
  17. Annotate helps with pointing to parts of the screen, (mouse arrow to leave marks, spotlight).

Personal Tips

  • Move your Zoom screen so that your own image is centered with your camera so that it appears that you are looking at the group.
  • Useful options:
  1. Touch up my appearance.
  2. Enable mirror effect.
  • Enable HD only if you have good bandwidth (not needed in most cases).
  • You can fix/change how your name is displayed by clicking on your own video image and clicking rename.
