# Live Events # Ways to broadcast a Live event We offer multiple ways to broadcast no matter the scale of your event, the venue, or the location of your presenters. When you schedule a Live event, you select how presenters will connect their audio and video to broadcast to the audience. The device or method is the *live acquisition source* for the event. **Note:** This only determines how your presenters connect their audio and video and broadcast to the audience. All webcast events include visual elements such as headshots, slides, overlay videos, and more. If presenters will speak to the audience but remain off-camera, select Telephone as the acquisition source. If they'll broadcast audio and video, you can use a single webcam, the video bridge for multiple webcams, an encoder, or a video conferencing unit (VCU). Available options depend on your account settings. Contact your sales representative or Support to request additional broadcasting options. [![Live Acquisition Sources dropdown with several choices](https://help.webcasts.com/uploads/images/gallery/2022-05/scaled-1680-/swXoRLxwt9Ol1lAr-liveacquisitionsources-cropped.jpeg)](https://help.webcasts.com/uploads/images/gallery/2022-05/swXoRLxwt9Ol1lAr-liveacquisitionsources-cropped.jpeg) # Broadcast audio only Select **Telephone** to broadcast the presenter audio with a telephone connection. Up to 20 presenters can stream their audio from a telephone or VoIP connection. Presenters dial in to the presenter bridge and a backup bridge is included as a backup audio source. # Broadcast audio and video There are several options for connecting presenters and streaming their audio and video to the audience. They can connect directly using their own webcams or connect to another system or service first and then stream that source into the event. - **Webcam** - A single webcam connection. Broadcast one presenter or several presenters using the same webcam. Before the event, you must install a driver on the computer you plan to use on the day of the event that lets the event connect to your webcam. Recommended if the event has only one presenter or one webcam source. - **Video Bridge** - For multiple presenter video streams. Allow up to 20 presenters to connect their webcams and broadcast. - **Advanced Video Bridge** - Allow presenters to broadcast from a video conferencing system, Skype for Business, or telephone audio. - **VCU (Video Conferencing Unit)** - Recommended for conference rooms. Use your own video conferencing unit to provide the video feed for the presentation. Before the event, get the H.323 or SIP address for the VCU and ensure it accepts incoming connections. In the Live Studio, the advanced video bridge uses the address to call out to the VCU and bring it into the event. - **Your Encoder** - Use your own RTMP-enabled encoding device to broadcast multiple webcams and microphones from your venue as a single stream. # Add live captioning to an event For Live events with StreamText captions only. The Webcast service does not have a built-in live captioning feature. However, you can create a custom tab and include real-time captioning delivered through the StreamText platform in your Live event. To include live captioning, you must request captioning services, set up a custom tab with the StreamText embed code, and then invite the captioner as an attendee. On the day of the event, the captioner joins as an attendee and types the captions into StreamText, which are then displayed to the audience in the custom tab. **Notes:** - You can't add live captioning to the archived version (replay) of a Live event. To add captions to an event replay, see [Add captions to a recorded event](https://help.webcasts.com/books/event-setup/page/add-captions-to-a-recorded-event). - Because live captioning is not a feature of this platform, Support is not able to set up, test, or manage captioning for self-service clients. If you would like someone to manage an end-to-end integration, contact your sales representative to arrange a consultation package. Jump to: [Request captioning services](#bkmrk-) | [Example code](#bkmrk--0) | [Set up the live captions tab](#bkmrk--1) | [Preview your work](#bkmrk--2) | [StreamText URL formatting](#bkmrk--3) # Request captioning services We can book live captioning for your event. **To request live captioning:** - If you have a Standard or Premiere plan, send us an email at . You can also use your own third-party captioning provider, as long as they use the StreamText platform. When you request live captioning through us, we provide your event ID to the captioning provider, who uses it to identify your event in their StreamText account. When you set up the custom tab, include this event ID in the embed code. If you schedule your own captioner, we recommend that you give them your event ID to use as their StreamText event name (identifier); confirm the value they used and include it in the embed code. To learn more about the process for scheduling captioning services, contact Support. # Example code Use the following example code to embed captions in the custom tab. In the code, find **event=1234567** in the code and replace **1234567** with the event ID for your event. If you're using your own captioning services, replace **1234567** with the event name provided by the captioner. **Important:** If you requested captions in a language other than English, you must include an additional language parameter to the link for them to display correctly. For example, if you requested captions in Spanish, you must add **&language=es** to the link after the event ID or name. For more information, see [StreamText URL formatting](#bkmrk--3). ``` ``` # Set up the live captions tab Sign in to the Webcast Admin portal and edit the Live event. **To add the live captions tab to an event:** 1. On the left panel, click the **Event Content** tab. 2. Under Optional Content, expand the **Add Custom Player Tabs** section and click **Add Sidebar Tab**. 3.

After you install it, the virtual webcam displays as a new webcam source that you can select when joining the event. If you are broadcasting an event with an advanced video bridge (ask your host if you're not sure), you can connect to the event from an online meeting app like Zoom or WebEx that offers virtual backgrounds. Supported virtual webcam apps include: - [CamTwist](http://camtwiststudio.com/) - [Chromacam](https://www.chromacam.me/) - [Manycam](https://manycam.com/) - [OBS](https://obsproject.com/) with Virtual Camera - [Snap Camera](https://snapcamera.snapchat.com/) - [Xsplit VCam](https://www.xsplit.com/vcam) **Note:** Download and test the app in the Live Studio at least 48 hours before the event starts. We do not provide support for third-party applications. # Change your background with a virtual webcam Before joining the Live event, start the virtual webcam app and set up your virtual background. **Important:** You must keep the virtual webcam running during the event for your virtual webcam to display properly. ## Single webcam **To connect to the event with a virtual webcam:** 1.

All streams are distributed at the bit rate set at the encoder. These are the system-recommended settings for each player size. These are also the settings that the system will transcode the streams to for the on-demand archive, regardless of live bit rate. With CBR events, you have the option to modify the streaming rate for a higher or lower live bit rate. **Important:** Streams that exceed 5,000 kbps will have their connection terminated by the system. It is recommended that streams not exceed 4,500 kbps. If you're broadcasting audio and video, the video player has the following layout options and streams to attendees at the listed bit rates. The audio bit rate is always 96 kbps and is included in the total bit rate.
Video Player SizeTotal Bit Rate
480p (854x480)896 kbps
720p (1280x720)1796 kbps
1080p (1920x1080)3096 kbps
### Slides Depending on the slide deck, events with slides require an additional ~50 kbps. Once an attendee joins the event, the slides begin downloading in the background regardless of the event’s live or pre-live status. ## Adaptive Bit Rate (ABR) Encoder Events You are only required to send one stream (per primary and backup). All streams are then transrated and keyframe aligned. If the client sends a higher stream than the bit rate listed in the Source Encoder Sending section, it will still get transrated down to the bit rate shown in the Audience Receives section. Sending a lower bit rate than what we ask the client to send is not recommended. If you're broadcasting audio and video, the video player has a widescreen (16:9) aspect ratio with the following layout options and streams to attendees at the listed bit rates. The audio bit rate is always 96 kbps and is included in the total bit rate. ### Source Encoder Sending

Then, copy and paste the **Primary** **Stream ID** into the stream setting of your encoder. Next, confirm that your encoding device is using the same settings as listed in the **Encoder Settings**. *NOTE: Bit rate can be adjusted based on your requirements.* To add a redundant backup stream on the event, copy and paste the **Backup Stream URL** from the **Encoder Settings** to the secondary encoding device settings. Then, copy and paste the **Backup** **Stream ID** into the stream setting of your encoder. Next, confirm that your secondary encoding device is using the same settings as listed in the **Encoder Settings**. *NOTE: Bit rate can be adjusted based on your requirements.* Start your encoder to begin streaming to the Webcast Server. Once your encoder confirms a successful connection, click the **Preview Stream** button to view the stream(s).

Please contact Support with questions. ## Overlay Videos The bit rate of overlay videos depends on the bit rate of the video when you uploaded it. If you uploaded a video: - Below 800 kbps, the video will be transcoded at 800 kbps - Between 800 to 1700 kbps, the video will be transcoded at the uploaded bit rate - Over 1700 kbps, the video will be transcoded to 1700 kbps # Presenter Best Practices Below are a list of best practices for presenters: # What should a presenter have available for the presentation? It is recommended that all speakers prepare the following: - For audio events, a telephone with a quality headset or handset for EACH presenter/presentation room. - Speakerphones have poor sound quality and tend to pick up background noise. If you must use a speakerphone try putting something padding under the phone (things around the office such as legal pads or newspapers will do the trick) and make sure the phone is away from computer fans, projectors, and air conditioning units. - Cellphones and cordless/wireless headsets or phones of any kind should be avoided as they are subject to disconnection and interference. - For video events, an speaker that will be on video should have an internal or USB webcam. - A quality headset is recommended as the audio source on video events. A webcam's internal microphone will work, but a headset will produce higher quality audio. - A hard copy printout of your slides. - Make sure you print out the same PPT file that has been uploaded. In case your computer or internet connection fails, you can reference your slides while someone else flips the slides for you without any interruption to your recording. - A wired internet connection. - Wireless can work, but we do not recommend it as the signal can be subject to drops and interference. Wireless internet should NOT be used for video events or screen sharing. - It is recommended that you test your system briefly before joining the events pre-call. - To further improve computer performance, it's recommended to restart your computer shortly before the event and close any unneeded programs or browser tabs. - Log off of your VPN - VPNs can reduce your available bandwidth, which is especially important when broadcasting video. We recommend logging off your VPN while presenting. # How can I test my system for presenting? For any testing, you should use the computer and browser that you intend to present from. Two seemingly identical computers can have very different program and system configurations. Once you have received the Guest Admin, please log into the webcast Live Studio to test your system. - Click the thumbnails or the **Next Slide** button in the slide tool to flip slides. If your computer is working correctly, you should see the slides advance. - There should be a Chat box in the lower left corner of your screen. Type a message into the box provided and click **Submit**. If your computer is working correctly, you should see your message in the Chat log. If you will be using your webcam or screen sharing on an event, please test your system here: [https://event.webcasts.com/test](https://event.webcasts.com/test/) Please note that if you run into any testing issues, you may be asked to provide a screen capture of the results of this system test. # What if I have issues with the Webcast Live Studio during a live call? The Live Studio checks the presenter's connection status approximately every three seconds. When the Live Studio detects a sustained connection drop (an approximate 10-15 sec. without a response from our servers), a message is displayed in the Live Studio alerting the presenter: *"Could not connect to the server. Please check your internet connection.(1)".* This message appears in an overlay and the presenter cannot click on any Live Studio elements while their connection is down. Once the connection has been reestablished, the message will disappear automatically and the presenter can resume their Live Studio interaction. If the Live Studio becomes unresponsive without an internet connection failure: - The presenter should first attempt to re-launch the Live Studio by closing the Live Studio browser window and clicking the "Launch Live Studio" button on the Guest Presenter page (or the Event Summary page for admins managing their own live events). - If the presenter is unable to re-establish their internet connection or the Live Studio remains unresponsive after re-launching, the presenter may need to contact their IT team for assistance. - If the presenter is unable to flip their slides for a sustained period of time, it is recommended to designate an individual (preferably a colleague familiar with the content) to assist with flipping slides for the webcast audience. The presenter should reference slide numbers from their print out copy of the slide deck as they speak to the material. # Share a video during a Live event In the Live Studio, the Overlay Videos tab shows all uploaded videos. From here, you and other presenters can preview them, play them for the audience, and stop sharing them. You can share a video as an overlay - in a separate window that covers the slides and video player - or play the video *inline,* in the video player. Once the event is archived, the recording includes the videos as they were seen by the audience during the live event. **Notes:** - Before your event goes live, have a least one presenter preview each overlay video. This helps to cache the videos on the event servers (content delivery network or CDN) and provide faster delivery during your event. - The stream is delayed for attendees, so you must allow the event to run for 15 seconds before sharing a video. This ensures all attendees see the video. - Once you share a video, you can only share it again the way you played it the first time (overlay or inline). For example, if you shared a video as an overlay, you can't share it in the video player. - All presenters are automatically muted while previewing and sharing a video. - You can't share a video and screen share at the same time. Jump to: [Preview a video](#bkmrk-) | [Share a video as an overlay](#bkmrk--0) | [Share a video in the video player (inline)](#bkmrk--1) | [Stop sharing a video](#bkmrk--2) # Preview a video Preview your overlay videos to make sure they display correctly to the audience during the live event. When you preview a video, the video is only visible to you. **To preview an overlay video:** 1. In the Live Studio, click the **Overlay Videos** tab. Thumbnails of the uploaded videos are displayed with the video name, size, and duration. 2. Under the video you want to test, click **Preview**.

Click **OK**. # Stream optimization It is important for any webcasting professional to understand if their network is ready to support a webcast. While our webcasting platform consumes far less bandwidth than major web conferencing tools, it still requires a high-speed connection to the internet to assure a quality user experience. Since the Webcast platform can support video-enabled webcasts for up to 10,000 attendees or more, there is a greater need to ensure your network can handle the attendance capacity. If your audience resides largely on a single corporate network, you may need to consult with the IT department to confirm there is adequate bandwidth to support your event. If adequate bandwidth is not available, you should consider leveraging one of the Webcast platform’s stream optimization solutions. These options include: - [Adaptive bitrate streaming](#adaptive) - [Peer-to-peer streaming](#p2p) - [Multicasting](#multicast) - [Stream caching](#stream-caching) # Adaptive bitrate streaming Adaptive bitrate streaming works by detecting a user's bandwidth and adjusting the quality of the video stream accordingly. This allows your webcast viewers to receive streaming video at an appropriate bitrate for their bandwidth, ensuring a high-quality experience for all participants. **Benefits of adaptive bitrate streaming:** - Allows viewers with high-speed internet connections to receive a HD quality video stream. - Viewers who do not have a high-speed internet connection, who may be on a public wifi connection or on a shared internet connection, will receive a lower bit-rate stream to ensure a buffering free video stream. - Adaptive bitrate streaming is fully automated in the Webcast platform, making the process seamless for viewers. # Peer-to-peer (P2P) streaming A P2P network optimizes video by enabling audience members to pull streams from other event participants on the same network. This method can reduce the amount of public IP bandwidth by up to 95%. A P2P solution requires a software client to be distributed to the global viewing audience by group policy or other installation method. The P2P software client is fully integrated with the webcast application and it automatically connects to, routes, and rebroadcasts video signals. We partner with Hive Streaming in this space for P2P stream delivery. **Benefits of P2P streaming:** - Allows a high volume of viewers on the same corporate network to view HD video with minimal impact on the corporate internet connection. - Once deployed the solution eliminates the need for the Network Engineering resources typically required to support video streaming using network appliances. - P2P streaming is fully automated, making the process seamless for viewers. # Multicasting In computer networking, “multicast is the delivery of a message or information to a group of destination computers simultaneously in a single transmission from the source.” Essentially multicasting takes one webcast video stream from the internet and redistributes it to internal viewers using a standard multicast IP. This alleviates the bandwidth strain put on the corporate network's internet connection. We partner with RAMP, the leader in HTML5 (HLS) multicasting. **Benefits of multicasting:** - Reaches large internal audiences with HD video without impacting either your corporate WAN or internet connection. - Offers self-service “plug and play” options and setup and testing provided by a webcast professional. # Stream caching Stream caching requires a minimum of two network appliances capable of intercepting, caching, and distributing video streams. This limits the amount of public IP bandwidth consumed by delivering streams from cache behind the firewall. While this method normally requires ongoing dedicated resources from an internal Network Engineering or Security team, once deployed the solution does not require any software to be distributed or maintained on end user machines. The Webcast platform fully supports video optimization using any device capable of caching HTML5 (HLS) streams, such as Blue Coat ProxySG. **Benefits of stream caching:** - Significantly reduces the bandwidth utilized by webcast viewers. - Stream caching with your webcast is seamless for viewers. # 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](#bkmrk-) - [Test your system](#bkmrk--0) - [Connect to the video bridge](#bkmrk--1) # System requirements All presenters and venues must meet the following minimum system requirements: - Operating system - 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 at 720p events. - 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?

# 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](#intro) | [How the video bridge fills the stage)](#fill) | [Voice-activated camera switching](#vacs) | [Pin presenters on stage](#pin) # 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](https://help.webcasts.com/books/live-events/page/about-presenter-webcam-layouts "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).
