What is a “live acquisition source”?

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.

If you're broadcasting audio only, you'll use Telephone as the acquisition source. If you're broadcasting audio and video, you'll use Webcam. Available options depend on your account settings.

What is the source location?

For video broadcasts only. The source location is the region you will be broadcasting the Live event from. By default, the source location is set to your current location based on your IP address. When scheduling the event, make sure the region is correct.

What size should the video player be?

For Live events with video, the video player is 480p with a widescreen (16:9) aspect ratio.

If you are broadcasting telephone audio only, the video player is set to 320 x 240 pixels for headshots and cannot be changed.

For On-Demand and Simulated Live events, primary media clips are also displayed in the video player. Upload media clips that match the player aspect ratio and size settings, or they will be stretched to fit in the video player.

Can I embed my event on another website?

Yes. You can embed your webinar into an external site with an iframe. You can embed the event window only or you can require attendees to register to access the event. To learn how, see Embedding an Event.


Where do I access the dial-in information for presenters?

The presenter access numbers and passcodes display in the Live Studio in the Broadcast Controls panel up to one hour before the event’s scheduled start time.

If you’re broadcasting audio with a third-party phone bridge, the event moderator provides the dial-in information to presenters.

Can I test the presenter audio before the event begins?

Yes. To test the presenter audio stream, join the Live Studio. Once presenters have connected their audio, click Connect Bridge to Webcast. Once the bridge is connected, click the Settings button (gear) and in the Additional Bridge Options window, click the Play button.

Can I add a telephone listening option for attendees?

Yes. You can allow attendees to listen to the event by phone and provide them with our access numbers and passcodes (the integrated phone bridge).

Can I add additional dial-in numbers for attendees when using an audience phone bridge?

Yes. If you’re using the integrated phone bridge and providing the audience with our access numbers and passcodes, you can add toll and toll-free numbers from up to 37 countries.

Single webcam

For Live events where only one webcam is connected.

Can I test my webcam connection before the event?

Yes. You can test your webcam in the Live Studio up to 60 minutes before the event's scheduled start time. To test your webcam, join the Live Studio, click Preview, and then select your webcam source.

Can I change the webcam I want to use?

Yes. You can change the webcam before the event goes live. Join the Live Studio, click Preview, and then you can select the webcam source you want to use. You can't switch webcams after you click Start Webcast.

Can multiple webcams be shared at the same time?

No. If you selected Webcam as the broadcast option when scheduling the event, you can only broadcast a single webcam.

Can I preview a presenter’s webcam?

Yes. Once the presenter has connected their webcam, join the Live Studio and click Preview.
