# Organize encodes in a CMAF Ingest output group
<a name="design-cmafi-package"></a>

A CMAF Ingest output group 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 captions or sidecar captions.

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