# Organize encodes in a MediaPackage output group
<a name="design-emp-hls-package"></a>

An MediaPackage output group is typically set up as a video ABR stack. A video ABR stack is an output group that contains the following:
+ More than one outputs.

Each output can contain the following:
+ One video encode (rendition). Typically, each video encode is a different resolution. 
+ Zero or more audio encodes. 
+ Zero or more captions encodes. 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.
