Video Bridge 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 Test your system Connect to the Video Bridge Connect to the Video Bridge using another source Navigate the Video Bridge System requirements All presenters and venues must meet the following minimum system requirements: Operating system - Windows 11, Windows 10, Windows 8.1+ Pro, macOS 10.14+ Processor - Intel Core i5 3.0GHz or equivalent RAM - 4GB Internet connection - A dedicated and hardwired high-speed connection of 1.5 Mbps+ (upload and download). We do not recommend using a Wi-Fi connection since it is prone to dips in bandwidth that can negatively impact your video connection. Internet Browser - Chrome (latest version), Firefox (latest version), Microsoft Edge (latest version) Note: Firefox does not support screensharing for Video Bridge. Webcam - High quality or HD webcast (for example, Logitech C920) Microphone - Headset microphone or webcam mic with built-in noise-cancelling Note: If you are using a microphone, use headphones or earbuds to prevent feedback from your computer speakers. Before the event, presenters and venues must also: Plug in their computers. Do not run an event on battery power. Disconnect from the VPN. Test your system before the event starts Don't want to read? Watch the video. 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:  Sign in to the Guest Admin site and click Live Presenter Studio. In the Live Studio, click Test your webcam. Enter your name and click Next. 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 and click Play Test Sound to make sure you can hear the event audio during the event. Click Join Bridge 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 Don't want to read? Watch the video. To join the video bridge: Sign in to the Guest Admin site and click Live Presenter Studio. Click Connect using my webcam. Enter your name and click Next.  Select the Microphone, Camera, and Audio Output sources you want to use for the broadcast. Confirm that the microphone volume level and webcam preview work properly. If you are a technical assistant or moderator who will not speak or appear on camera, click the Mic button to mute your microphone and click the Camera button to turn off your webcam. Click Play Test Sound to make sure you can hear the event audio during the event. Click Join Bridge. 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:   Sign in to the Guest Admin site and click Live Presenter Studio. Click Connect using another source. 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. Navigate the Video Bridge Once connected to the video bridge, presenters will be able to see and communicate with other presenters on the Video Bridge. Once the event begins, you'll see "On Air" at the top of the window to confirm you are live to viewers. You can now speak, advance slides and use other controls for the event. Please confirm your responsibilities for the presentation with the event's moderator.At the bottom of the video bridge window, each presenter has buttons to control their connection. Click on the camera icon to hide your camera from displaying to viewers or click on the microphone button to mute your audio. These local controls can be toggled on/off during the event as needed. Click on the monitor icon to share your screen with viewers at any time during the event.NOTE: If you do not see the option to share your screen, contact Support.When sharing your screen, a pop-up window will appear allowing you to select what content you want to share. Select one of the tabs along the top: a Chrome Tab, Window (or application), or your Entire Screen. Under that tab select from the available options. Under the selected tab, select one of the available options and click Share to make your screen share active to viewers. Once active, viewers will see the selected screen share application, a small window in the top right with the camera for the presenter sharing their screen, and a shared audio feed from the video bridge. Presenters should minimize their Live Studio and begin their screen share. Once complete, click Stop Sharing to end the screen share.  About the video bridge (moderators) As a moderator, you have full control of presenters and video bridge functions. You can share your webcam, share your screen or an application window (720p or 1080p events only), and manage your own event experience. Click on a presenter's name to hide their webcam, mute their audio, update their name, promote them to a moderator, and disconnect them from the video bridge. If you're using an advanced video bridge, you can also lock the Live Studio to prevent other presenters from joining, dial out to a Microsoft Teams or Zoom room or Skype for Business using a SIP, H.323, or RTMP connection, and stream to an external platform like Youtube Live or Facebook Live. The following example shows the moderator view of the video bridge with a 720p video player and advanced video bridge turned on.

About presenter webcam layouts 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 presenter webcam layouts, explains how voice-activated camera switching works with them to manage who is on stage, and how you can manually "pin" presenters on stage. 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. Jump to: Presenter webcam layouts | How the video bridge fills the stage) | Voice-activated camera switching | Pin presenters on stage 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 - Single Speaker layout. You can change this layout before the event begins and at any time during the Live event. Layouts include: Single Speaker - displays one presenter at a time. This is the default layout. Grid – displays up to 4, 9, 16, or 20 presenters in equally-sized frames Filmstrip - displays up to 8 or 20 presenters, with one or two presenters highlighted in large frames above a filmstrip with the other presenters 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, their frame is still displayed on stage and is blacked out. By default, the Single Speaker webcam layout is selected and the first presenter who joined is displayed on stage. In Grid layouts, frames are filled from left to right, one row at a time. Once a row is filled, a new row starts below the previous one. The first presenter to join with a webcam is in the top left frame. In Filmstrip layouts, the first one (or two) presenters who joined are displayed in the large frames, and remaining presenters fill the filmstrip from left to right, in the order they joined. Like grids, a new row starts once the first row is filled. The filmstrip has seven frames per row. The 20-presenter filmstrip has three available rows. 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 you join the video bridge, voice-activated camera switching is on by default. 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.  In the Single Speaker layout, the active talker replaces the presenter that spoke previously. In Grid layouts, presenters remain in their own frames while speaking. If an off-stage presenter speaks, that presenter moves to the grid, replacing the presenter who spoke least recently, no matter where they are in the grid. In Filmstrip layouts, the active talker is displayed in a large frame above the filmstrip. In the two-frame layout, the large frames show the active talker and the presenter who spoke immediately before. The filmstrip shows a history of presenters who have spoken, left to right from most to least recently. When a person in the filmstrip 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. Pin presenters on stage To choose who is on stage, turn off voice-activated camera switching and pin presenters. Pinned presenters remain on stage whether they are speaking or not. The number of presenters you can pin is limited by the number of frames included in the layout. When there are more presenters than spots available, other speakers remain off-stage, but can still be heard when they speak. To remove presenters from the stage, unpin them. In the Single Speaker layout, pin the presenter you want to keep on stage. In the presenter list, a yellow star indicates which presenter is highlighted (that is, pinned on stage). In Grid layouts, pin the presenters you want to keep on stage, up to the number of spots in the grid. If they were already on stage, presenters remain in their places when you pin them. In Filmstrip layouts, presenters are displayed in the order that you pin them, starting with the large frames and then filling the filmstrip from left to right. The first one (or two) presenters you pin are highlighted in the large frames above the filmstrip as lead presenters. Set the lead presenters (filmstrip only) In the presenter list, pins are numbered to let you know the order the presenter webcams are displayed. The yellow star next to pin 1 (and pin 2) indicates those presenters are highlighted in the large frames above the filmstrip. To move a presenter to a large frame above the filmstrip, click their Up arrow button. 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 with pin 2 is bumped to the filmstrip.Change the presenter webcam layout on the video bridge Change the webcam layout to display more presenters during the Live event. By default, the Single Speaker 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. By default, Voice Activated Camera Switching is turned on and displays the active speaker (and recent speakers when using the Grid or Filmstrip layout). To display specific presenter webcams to the audience, see Pin presenter webcams on the video bridge.Note: Only moderators can change the presenter webcam layout. To allow a presenter to change the webcam layout, promote them to a moderator. To change the presenter webcam layout: In the Live Studio, under the presenter list, click Webcast Layout Control. Select the number of presenter webcams you want to display. For: Single Speaker layout, one presenter is already selected. Grid layouts, you can select a 2x2, 3x3, 4x4, or 5x4 grid. Filmstrip layouts, you can show up to 8 presenters with one presenter highlighted in a large frame or 20 presenters with one or two presenters highlighted. Optional. Select Display Video Presenter Names to show the names of presenters at the bottom of their webcams. Display Audio Presenters Names and Voice Activated Camera Switching are turned on by default. Click Apply. Pin presenter webcams on the video bridge By default, voice-activated camera switching is turned on and controls who is on stage. If you'd like to choose which presenter webcams are on stage, turn off voice-activated camera switching and pin presenters to the video bridge. In Filmstrip layouts, you can also select the presenters to highlight above the filmstrip. To learn more, see About presenter webcam layouts. Note: Only moderators can pin presenter webcams. To allow a presenter to pin webcams, promote them to the Presenter role.
