An MediaPackage output group is typically set up as a video ABR stack. The term ABR stands for adaptive bitrate. A video ABR stack is an output group that contains the following:
-
One or more outputs.
-
Multiple versions (renditions) of the video. Each rendition has a different resolution.
-
Zero or more audio encodes. Typically, there are multiple audio encodes.
-
Zero or more captions encodes. Typically, there are caption languages to match the audio languages. The captions are embedded or object-style captions.
This diagram illustrates a MediaPackage output group when the captions are embedded in the video. Each video encode is in a separate output. The captions are in each video output. Each audio encode is in a separate output.

This diagram illustrates a MediaPackage output group when the captions are sidecar captions. Each encode is in its own output.
