# Step 4: Set up the output groups and outputs
Step 4: Set up output groups

This section shows how to set up output groups and outputs in an Elemental Live event that implements output locking. 

**Note**  
This section refers to *pools*. For an explanation of pools, see [Output locking pools](opl-pools.md).

After you set up all of the events that you have identified, use the following topics to set up the outputs.

# Setting up an HLS output group
HLS

This section shows how to set up an HLS output group to implement Elemental Live output locking. 

1. Complete the fields in the **Apple HLS Settings** section of the output group. Set the fields that are listed in the following table as specified in the table.     
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/elemental-live/latest/ug/opl-setup-hls.html)

1. Set other fields in the **Apple HLS Settings** section to suit your workflow. 

1. Set the fields in the outputs to suit your workflow. 

# Setting up an MS Smooth output group
MS Smooth

This section shows how to set up an MS Smooth output group to implement Elemental Live output locking. 

1. Go to the **MS Smooth Settings** section of the output group. Set the fields that are listed in the following table as specified in the table.

# Setting up a UDP/TS output group
UDP/TS

This section shows how to set up a UDP/TS output group to implement Elemental Live output locking. 

1. Go to the **UDP/TS Output Group **section of the event. Set the fields as follows.
   + **Custom Group Name**: Enter the same name across all events in the pool. 
   + Set other fields to suit your workflow.

1. Go to each output. In the **Transport Stream Settings** section, set the fields as specified in the following table.
