Ways to broadcast a Live webinar
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 webinar 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.
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
Select Webcam to broadcast the presenter audio and video with a single webcam. You can 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.
How do I broadcast my telephone presentation?
All presenters will dial in to the Presenter Bridge number and enter the Passcode listed in the Broadcast Controls area of the Live Studio. Once a telephone line has been connected to the Presenter Bridge, you will see the Presenter count update below the bridge. The Presenter Bridge can then be connected to the Webcast Audio Server using the Connect Bridge to Webcast button.
Once the Presenter Bridge has been connected to the Webcast Audio Server, a message will be displayed on your screen and the Start Webcast button will appear. The connection process can take up to two minutes to complete. You will remain in a private sub-conference until you click the Start Webcast button to begin your presentation.
Once the Presenter Bridge has been connected, you can access additional phone bridge controls using the gear icon in the top right of the Presenter Bridge controls.
In the pop-out window, click the play button to preview the audience stream on the event before going live. This allows you to ensure the Presenter Bridge audio is coming through loud and clear before starting the presentation. The audio preview will stream through your computer speakers or a headset. If you encounter issues with Presenter Bridge during the presentation, click Switch Audio Source to Alternate Bridge on this screen to access the Backup Bridge for the presentation.
Each event will include a Backup Bridge to allow to switch the event's audio source in case there are issues with the Presenter Bridge. In order to switch to the Backup Bridge, dial in to the Backup Bridge number and enter the Passcode displayed. Once a telephone line has been connected to the Backup Bridge, you will see the Presenter count update below the bridge. Click Connect to prepare the bridge for broadcast. If you need to switch to the Backup Bridge during the event, click Set as Webcast Audio Source to switch the event's audio source. Other presenters in the Live Studio will be prompted to disconnect from the Presenter Bridge and dial into the new Backup Bridge in order to connect their telephone line.
If you will be using an external operator-assisted phone bridge for the event, all presenters will dial into the bridge number included in your call confirmation details and not the Presenter Bridge from the Live Studio. The event's host will need to provide the operator with the Presenter Bridge and Passcode from the Live Studio to allow the operator to dial out to the Presenter Bridge. Once the Operator has joined the Presenter Bridge to the conference, the bridge will list 1 Presenters on the bridge and the audio can then be connected in the Live Studio using the Connect Bridge to Webcast button. You will remain in a private sub-conference until you click the Start Webcast button to begin your presentation.
When using an operator-assisted phone bridge, it is recommended to provide the operator with the Backup Bridge information in addition to the primary Presenter Bridge. This allows the operator to dial out to both phone bridges for the presentation. In case of issues with the primary Presenter Bridge, the event can easily be switched to the Backup Bridge to ensure your broadcast is not interrupted.
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
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.
- 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.
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:
- In the Live Studio, click the Overlay Videos tab.
Thumbnails of the uploaded videos are displayed with the video name, size, and duration.
- Under the video you want to test, click Preview.
The video plays in a new window as an overlay.
Note: The audio is muted when you preview a video. To test the video's audio, click Listen to Presentation Audio.
