Step 2: Set up inputs

After you have identified the sources and ensured that they [support output locking](output-locking-requirements.md#output-locking-output-requirements), you can set them up in the event as inputs.

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

**To set up the inputs**

1. Create all of the inputs that you have identified. Create the same inputs in each event, and enter them in the same order in each event.

1. Complete all fields that apply to the input type.

   In the **Input – Video Selector** section of the event: Set the following fields as specified in the following table.
