New features and functionality 

New options for broadcasts to Facebook Live

Wowza ClearCaster includes several enhancements and new features for broadcasts to Facebook Live. For more information, see Create a Wowza ClearCaster broadcast for Facebook Live.

Beta support for adding titling and graphics  to Facebook Live broadcasts

When configuring Wowza ClearCaster broadcasts to Facebook Live in Wowza ClearCaster Manager, you now have the option to add browser-based graphics overlays to the broadcasts. When using this beta feature, the video source is encoded, and then the graphics overlays are superimposed on top of the video. This ensures that even if something happens to your graphics application during a broadcast, the video stream will continue without interruption. We are most closely integrated with Vidpresso:LIVE, but you can also configure a broadcast to use other graphics applications as long as they output a URL. For more information, see Add titling and graphics to a Wowza ClearCaster broadcast

Note: The Titling and Graphics functionality, including integration with Vidpresso, is a beta. You may experience unpredictable behavior when using this feature. Contact Wowza Support to request access to the Videpresso integration beta.

Redundancy for broadcasts

You can now configure Wowza ClearCaster broadcasts to Facebook like with a primary ClearCaster device as well as a secondary, redundant ClearCaster device that will only be used in case of a failure with the broadcast from the primary ClearCaster. Note that this option is only available if you have more than one ClearCaster registered with your Wowza account. For more information, see Set up redundant ClearCaster live streams for Facebook Live broadcasts.

Donations on Facebook Live broadcasts

You can now add a Donate button to your broadcasts to a Timeline or a verified Facebook Page for a nonprofit or charity. For more information on Facebook's strict requirements for eligibility, see Facebook Charitable Giving Tools.

Rotated vertical (9:16) aspect ratios

We've enhanced the vertical aspect ratio offerings to include the ability to rotate the video to the left or right by 90 degrees. This can be selected on a per-broadcast basis.

Support for simulcasting to Wowza Streaming Cloud while in preview 

We've added an option when adding a simulcast target that allows you to enable the target to simulcast to Wowza Streaming Cloud while the Facebook Live broadcast is in preview. This is a great way to ensure your simulcast workflow is working when you go live. For more information, see Simulcast a Wowza ClearCaster Live Stream on Facebook Live and Wowza Streaming Cloud.

New network configuration tool

The new Wowza ClearCaster Network Configuration Tool, available in ClearCaster Manager under the Support tab, makes it easier to configure network settings for your ClearCaster device. This tool enables you to assign a static IP address and use DNS servers. For more information, see How to manage Wowza ClearCaster network IP settings.

Support for broadcasting to Workplace by Facebook

Facebook Live ( remains the primary use-case for Wowza ClearCaster devices, but you can now request access to use your ClearCaster device with Workplace by Facebook. When granted access, all you need to do is update a device-level setting and pair the Workplace account with the ClearCaster. To request access, contact Wowza Support. For more information, see How to configure Wowza ClearCaster to stream to Workplace by Facebook.
