Video Bridge Guide for Presenters and Guest Admins

A Video Bridge allows presenters to connect to an event and broadcast from different camera sources and locations. As a presenter, you will join the event from your computer and connect the video source that you'll use to speak to the audience. Often this is a webcam, but you can also broadcast and present from a video conferencing system, Skype for Business, or a telephone (where you're not on camera).

Use this guide to learn how to test your system and connect to the Video Bridge. This guide contains the following topics:


System Requirements

All presenters and venues must meet the following minimum system requirements:


Before the event, presenters and venues must also:


Test your System Before the Event Starts

It's important that you make sure your system is compatible before the event begins to identify and resolve any issues. At least 48 hours before the event, join the Live Studio and run a diagnostic on your system with the network and equipment you plan to use on the day of the event. This checks the quality of your audio and video connections. 

You should have received an email with login details and a link to the Guest Admin or Guest Presenter Access site. The Guest Admin site includes a button that lets you enter the Live Studio.

To test your webcam and microphone: 

  1. Sign in to the Guest Admin site and click Live Presenter Studio.
  2. In the Live Studio, click Test your webcam

  4. Select the Microphone, Camera, and Audio Output sources you will use during the event. Confirm that the microphone volume level and webcam preview work properly. Click Test your speakers to make sure you can hear the event audio during the event.

    Note: If this is your first time connecting to the platform, you may be prompted to allow access to your camera and microphone before you can select your camera and microphone source. Click Request permission in the center of your screen if prompted.

    A pop-up in the top left will allow you to select what if you would like to allow access this time only or allow access for every visit.

  5. Click Join now and follow the guided connection test instructions.

    The test records a short clip of your audio and video and plays it back to you. Make sure the video plays clearly, without feedback or echo. If it does not record correctly, there could be a network connection issue. Check that you have a wired (LAN) connection to the internet and that it is active.

    If you have any issues, run the test again. If you continue to have issues, contact support or your event host.

  6. Click Join now.

    Note: The Video Bridge utilizes UDP/TCP RTP Media Traffic over ports 4000-5000 to connect a webcam. If a presenter’s connection to the Video Bridge is blocked by their network, the system will automatically failover to use TCP 443 (HTTPS).
     
    This failover is intended for presenters behind on a restricted network to ensure a connection can be made. However, TCP media is often subject to a noticeable delay and synchronization issues between audio and motion, as well as a delay on content share streams. It's always better to use a UDP/RTP connection whenever possible. For that reason, it is recommended that presenters disconnect from VPN before presenting. It is also recommended to test your system in advance to ensure there aren’t any issues connecting on the live event.

If you are not able to connect to the Video Bridge, are experiencing issues with your audio/video stream on the Video Bridge due to a connection or network issue, or prefer to join from another source, the Video Bridge has additional connection options.
