# 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.

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. # Join the Live Studio To moderate or present at a live event, enter the Live Studio and connect your audio or video. The Live Studio has controls for presenting slides, playing videos and other content, managing Q&A, and more. The way you join the Live Studio depends on whether you have a webcasting account or whether you were invited to be a presenter or assist with Q&A. # Join as a moderator If you have a webcasting account, sign in to the Webcast Admin portal and in the My Events list, click **Edit** to open the Live event. On the Event Summary tab, under Run My Event, click **Launch Live Studio**.

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.

Interprefy allows multi-language support by providing viewers with real-time interpretation in multiple languages. The audio interpretation widget can be added to Live audio-only or video webcasts. **Note:** Webcasts support audio interpretation services only. Video interpretation services are not supported. # Schedule your Interprefy event Before your event, you must reach out to Interprefy directly to schedule an interpreter and receive an Interprefy widget link. Your Interprefy widget link should look like this: [https://interpret.world/login=widgetdemo](https://interpret.world/login=widgetdemo) For managed events, you must provide the event production manager with the Interprefy widget link at least 72 hours before the event start time. # Example code Use the following sample code to embed the Interprefy widget. Replace **https://interpret.world/login=widgetdemo with your Interprefy widget link. ```HTML
