# Step 4: Set up the output groups and outputs
<a name="opl-setup-output-groups"></a>

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
<a name="opl-setup-hls"></a>

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 a UDP/TS output group
<a name="opl-setup-udp"></a>

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.
