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. 

    image-1710349998742.png

  3. Enter your name and click Next.

    image-1709581988940.png

  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.

    image-1709582040975.png

  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.

Connect to the Video Bridge


To join the Video Bridge:

  1. Sign in to the Guest Admin site and click Live Presenter Studio.
  2. Click Join using my webcam.

    image-1710350777656.png

  3. Enter your name and click Next. 

    image-1709650230496.png

  4. Select the Microphone, Camera, and Audio Output sources you want to use for the broadcast using the available dropdowns. Confirm that webcam preview work properly and that your microphone audio is being registered on the microphone icon in the webcam preview window. Click Test your speakers to make sure you can hear the event audio during the event.

    image-1709650380984.png


    If you are a technical assistant or moderator who will not speak or appear on camera, use the microphone icon or camera icon in the lower right of the video preview to mute your microphone or turn off your webcam.

    image-1709650435166.png

  5. In the lower right of the video preview, click on the person icon to add a blurred or virtual background to your video stream.

    image-1709652974717.png

  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.


Connect to the Video Bridge using Another Source

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.

To join the Video Bridge:

  1. Sign in to the Guest Admin site and click Live Presenter Studio.
  2. Click Join another way.

    image-1710350847439.png

  3. You will options to connect via Telephone, Skype for Business/Lync, or Video Conferencing Unit using H.323, SIP or a video Bridge Domain. Follow the instructions listed below to connect.

About Presenter Webcam Layouts on the Video Bridge

On the video bridge, you can choose how you want to arrange presenter webcams and which presenters to display to the audience during the Live event. This article introduces instructions on how to access Layout, the available Layout options, and details on how to spotlight an individual presenter and how you hide presenters from appearing to the audience.

Important: To see the video bridge and interact with other presenters, you must join with a webcam. Presenters who select I will not be appearing on camera won't be able to see or hear presenters who have joined the video bridge.

This guide contains the following topics:


Presenter Webcam Layouts

Presenter webcam layouts control the number of presenters on stage and how their webcams are arranged. By default, the event shows one presenter - Individual layout. You can change this layout before the event begins and at any time during the Live event. To access Layouts, click on the gear icon in the top right of the Video Bridge and select the Meeting Layout text.

image-1723831805193.png

Select from the available layouts by clicking on the thumbnail. 

image-1723831825864.png

Layout options include: 


How the Video Bridge Fills the Stage

The frames in the layout are initially filled in the order that presenters join with a webcam. The number of available spots on stage depends on your selected layout. The Video Bridge doesn't set aside empty frames; instead it adds frames as needed, for each presenter.

Note: If a presenter joins with a webcam and then turns off their webcam, they will be hidden from display in the selected layout.

That's the initial order. Now let's look at voice-activated camera switching.

Voice-Activated Camera Switching

Voice-activated camera switching tracks when presenters speak and keeps a history of most to least-recent speakers. It uses this information to adjust who is on stage and makes sure the active talker is visible. This varies depending on the webcam layout you select. 

When there are more presenters than spots available, other presenters remain off-stage until they speak. Then, voice-activated camera switching moves them to the stage, bumping another presenter off. 

When a person in the filmstrip or speaker layouts speaks, they move to a large frame and the person previously in that frame moves to the first spot in the filmstrip, shifting other presenters to the right. In the two-frame layout, the presenter in the large frame who spoke less recently is replaced.

Prioritizing Presenters on Stage

The Spotlight feature can be used to pin a presenter as the primary video in a layout, whether they are speaking or not. To spotlight a speaker, click on the star icon next to the presenter in the Presenter list.  

image-1723831925549.png

When a presenter is spotlighted, the star icon next to their name will be highlighted. Click on this icon to remove the spotlight.

image-1723831944018.png

Multiple presenters can be spotlighted if required. This can be used for layouts featuring two (or more) large frames. Spotlighted speakers will appear in the order the Spotlight was added.


Hiding Presenters on Stage

If you want to hide a presenter from appearing in the video stream, their camera needs to be disabled. Presenters can hide their camera locally using the camera icon along the bottom of the Video Bridge.

image-1723831978852.png

Administrators can also hide any presenter's camera themselves. Click on the camera icon next to the presenter in the Presenter List. 

image-1723832013560.png

When a presenter's camera is muted, the camera icon next to their name will be highlighted. Click on this icon to unmute their video.

image-1723832029614.png

Note: An administrator's mute/unmute camera controls operate independently from a presenter's local controls. If a presenter mutes their camera locally, an administrator can't unmute them and vice versa.

Change the Presenter Webcam Layout on the Video Bridge

Change the webcam layout to display more presenters during the Live event. By default, the Individual layout is selected and displays the active talker to the audience. You can change this layout before the event begins and switch layouts any time during the Live event. To learn more about presenter webcam layouts, see About Presenter Webcam Layouts.

Voice-activated camera switching is used to displays the active speaker (and recent speakers when using the Grid or Filmstrip layout). To display specific presenter webcams to the audience, see Spotlight Presenter Webcams on the Video Bridge.

Note: Only Hosts can change the presenter Video Bridge layout. To allow a presenter to change the layout, promote them to the Host role using the settings next to a speaker in the Presenter list.

To change the presenter Video Bridge layout:

Adding Virtual Backgrounds on the Video Bridge

Virtual and blurred background are available to presenters connecting their webcam to the Video Bridge. Virtual backgrounds can be added before joining the Video Bridge or after connected to the Video Bridge. Follow the instructions below to include a virtual background on your video: This article also includes best practices for virtual backgrounds.

Adding a Background Before Joining the Video Bridge

Custom Background Images

For custom virtual background images, we recommend images using the following minimum specs:

Troubleshooting

If the virtual background option does not appear, this is may due to a browser setting. Please enable your browser's hardware acceleration, which allows for smoother browsing, audio/video streaming, and overall experience.

Spotlight Presenter Webcams on the Video Bridge

Voice-activated camera switching is used by default to control which cameras appear to the audience. 

The Spotlight feature can be used to pin a presenter as the primary video in a layout, whether they are speaking or not. To spotlight a speaker, click on the star icon next to the presenter in the Presenter list. 

image-1723831511728.png

When a presenter is spotlighted, the star icon next to their name will be highlighted. Click on this icon to remove the spotlight.

image-1723831546504.png

Multiple presenters can be spotlighted if required. This can be used for layouts featuring two (or more) large frames. Spotlighted speakers will appear in the order the Spotlight was added.
 
To learn more, see About Presenter Webcam Layouts.

Hiding Presenters from Appearing on the Video Bridge

If you want to hide a presenter from appearing in the video stream, their webcam needs to be disabled. If a presenter's camera is disabled, their video will not be visible and they will not appear in the selected layout.

Presenters can hide their camera locally using the camera icon in the lower right of the Video Bridge. 

image-1723832627569.png

Administrators can also hide any presenter's camera themselves. Click on the camera icon next to the presenter in the Presenter List.

image-1723832667902.png

When a presenter's camera is muted, the camera icon next to their name will be highlighted. Click on this icon to unmute their video.

image-1723832673999.png

Note: An administrator's mute/unmute camera controls operate independently from a presenter's local controls. If a presenter mutes their camera locally, an administrator can't unmute them and vice versa.


Video Bridge Integrations - Zoom

The Webcast platform allows for external video streams to be connected to the Video Bridge. This article will cover instructions on incorporating a Zoom meeting to your Video Bridge event. Topics include:

Presenter Requirements

GoTo Webinar Extensions is a broadcast product with defined roles for Presenters and participant / audience members. Network requirements for both roles can be found on our Network Requirements page. For Presenters, refer to the Webcast Presenters - Video Events column along the right for the requirements. Click Notify Me About Network Updates in the top right to sign-up to receive email updates regarding any planned network changes. We do our best to minimize updates to avoid impacting your IT and Network teams. 

Please be sure to add the domain names, protocols / ports, and IP Ranges for specific to the Video Bridge. This will allow your Presenter(s) to connect their webcam(s) through their current Chrome, Edge Chromium, or Firefox browser using WebRTC. It is critical that the IPs are allowed, and not just the domain wild cards, because the connection is established using the ICE protocol, which negotiates based on IP addresses. 

When adding allow rules to the network, it is important to consider how the Presenter(s) will be joining and what security solutions their video/audio traffic could be traversing. For example, will Presenters be on the corporate network on off-site? If they are off-site, will they be on VPN? For Presenters off-site and on VPN, we recommend enabling split tunnel.  

Firewalls also need to have allow rules enabled to have traffic flow bi-directionally in order for Presenter(s) to share their video and to see other presenters’ videos. 

With cloud security services (example: Zscaler) or other products such as cloud proxies, it is important to add allow rules using the information outlined in our Network Requirements page. When possible, we recommend bypassing proxies as a best practice.  

Additionally, please be mindful of security software solutions (example: Netskope) that may be deployed in the corporate environment. Note: Netskope requires a list of FQDNs. Please reach out to support@webcasts.com and include the associated GlobalMeet webcast event ID to receive the FQDNs. 

Please review our Knowledge Base article on our Video Bridge for additional information. 

Connecting to Social Media for Live Streaming

The GlobalMeet Webcast platform allows the Video Bridge to be connected to an external social media site to allow the content to be simultaneously live streamed. This article will cover instructions on connecting your Video Bridge to an external site. Topics include: 

How to Connect to an External Site

When you join the Live Studio for the event, the Video Bridge tab will appear by default. The event host that will be connecting to the external site needs click Join using my webcam. This allows you to initiate the Video Bridge, access to the advanced Video Bridge controls, and the ability to connect/start/end the event.

Once you have connected your webcam, click on the gear icon in the top right of the Video Bridge. Then, select Dial Out to a Presenter.

A pop-up window will appear where you can enter the details to connect to an external source. For Protocol, select "RTMP Stream". In the Destination Address field, enter the RTMP Stream where you want to connect the steam. This address will be provided by the service where you are connecting the stream. In the Optional Display Name field, enter an optional name to help you identify the stream in the Presenter List. Click Dial when you are ready to connect the stream.

Once the stream has been connected to the external service, you will be able to go live using the controls on that site.


Notes: The streaming service you are connecting to should provide the RTMP stream information to be used. Usually the URL and stream key are separate, so you will need to add a slash to the end of the URL to append the stream key.

Both RTMP and RTMPS streams are supported. For RTMPS streams, you need to include ":443" in the streaming URL.

Below are some example of how the full URLs will look:
