About built-in Wowza ClearCaster universal mode destination and encoding options

With Wowza ClearCaster™ Pro, you can broadcast to a wide variety of destinations including the Wowza Streaming Cloud™ service; a Wowza Streaming Engine™ instance; video-sharing websites such as Facebook, YouTube, Twitch, and Twitter; and other destinations. You can select from pre-tuned encoding templates for each destination to provide the best experience possible.

This article provides information about destinations, pre-tuned encoding templates, and frame rate considerations to help you decide which destination and template meet your needs. 

Compare destinations and pre-tuned encoding templates


ClearCaster universal mode allows you to create broadcasts that deliver streams to the following RTMP-based destinations. Use the tables in each section to compare encoding preset options. For additional information about frame rate settings, see Frame rate considerations.

Wowza Stream Name

Use the Wowza Stream Name destination to stream to a Wowza Streaming Engine instance or the Wowza Streaming Cloud service using H.264 or H.265 (HEVC). 

Note: When using the Wowza HEVC encoding presets to stream to Wowza Streaming Cloud, you can't use the default option of passthrough. Instead, you must transcode the video to H.264.

Bitrate considerations


All of the encoding templates are designed to automatically adjust the bitrate for a more positive playback experience. Each template has a target bitrate, which functions as a maximum, and a minimum bitrate. Together, the target bitrate and minimum bitrate define the acceptable range in bitrates for the stream.

When monitoring a stream in the Wowza ClearCaster Manager, you'll also see the available bitrate and actual bitrate when a stream is live. To determine the available bitrate, the target bitrate is adjusted based on network conditions. The actual bitrate also depends on network conditions as well as the amount of motion within the video. Don't expect the actual bitrate to match the target bitrate.

Frame rate considerations


When comparing encoding templates, note that the frame rate listed is the maximum video capture frame rate. This is the maxium frames per second that ClearCaster can process using an encoding configuration.

If your video source sends a stream with a frame rate less than the maximum frame rate listed, ClearCaster processes it as is without adding any additional frames. If your video source sends a stream with a frame rate higher than the maximum frame rate listed, ClearCaster halves the frame rate of your video source.
