How to Enable Adaptive Bitrate (ABR) in Castr

Castr supports adaptive bitrate streaming for our HTML5 players.

ABR is included with Professional or higher plans. (If you have a legacy plan, you can still access this feature if you have All in One Plus or higher plans)

Here's how to enable it on the Video Settings tab:

  1. Go to a Live Stream project.

  2. Click on Video Settings > Adaptive Bitrate

  3. Toggle on the Enable Adaptive Bitrate Transcoding button

The stream is now transcoded and delivered in multiple bitrates from Castr. 

Note: It's highly recommended to set the incoming bitrate of the stream to 4000 kbps to 5000 kbps for better performance.

What is Adaptive Bitrate Streaming?

Adaptive bitrate (ABR) is a video streaming technology that helps to deliver video in the highest quality possible based on the user’s bandwidth and device capacity.

In ABR, videos are transcoded real-time and compressed at a number of different rates; We transcode one single video source to multiple versions of different bitrates.

If your internet bandwidth doesn’t allow for streaming the 4000 Kbps version, you can still view the same video at a lower bitrate, for example, 2,500 Kbps.

Read through the rest of our blog to learn more about adaptive bitrate streaming.

If you need any extra help with ABR, please contact our support team.
