Live Events

Broadcast and present a Live event.

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

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.

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.

Request captioning services

We can book live captioning for your event.

To request live captioning:

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.

Add a virtual background to your webcam or video stream

The Webcast service does not currently offer virtual backgrounds; however, if you're broadcasting a single webcam or multiple webcams (video bridge) during the event, you can add them to your video stream with a third-party virtual webcam app. A virtual webcam app is software that allows you to add virtual backgrounds, filters, and more to your webcam video. 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:

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.

Encoder stream bit rates (ABR and CBR)

Constant Bit Rate (CBR) Encoder Events (Recommended)

You are only required to send one stream (per primary and backup). 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 Size Total 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

Video Player Size Total Bit Rate
480p (854x480) 896 kbps
720p (1280x720) 1796 kbps
1080p (1920x1080) 3096 kbps

Presenter Best Practices

Below are a list of best practices for presenters:

What should a presenter have available for the presentation?

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.


If you will be using your webcam or screen sharing on an event, please test your system here:  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:

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.
