# Complete channel and input details
<a name="creating-a-channel-step1"></a>

The **Channel and input details** section of the **Create channel** page lets you do the following in the MediaLive that you are creating:
+ Select the IAM role that AWS Elemental MediaLive will use to access the channel when the channel is running (started).
+ Optionally select a template to use.
+ Select the channel class.
+ Complete input specification information.
+ Set up tagging.

**To provide channel and input details**

1. Open the MediaLive console at [https://console.aws.amazon.com/medialive/](https://console.aws.amazon.com/medialive/).

1. Before creating a channel, make sure that you have [created the inputs](creating-input.md) that you will attach to the channel.

1. On the MediaLive home page, choose **Create channel**, and in the navigation pane, choose **Channels**. 

   If you've created a channel before, you won't see the home page. In that case, in the MediaLive navigation pane, choose **Channels**, and then choose **Create channel**.

1. On the **Create channel** page, choose **Channel and input details**.

1. Complete the sections:
   + In **General info**, for **Channel name**, type a name for your channel. 
   + In **General info**, complete **IAM role**. See [IAM role and ARN](role-and-remember-arn.md). 
   + You can optionally configure the channel by selecting and loading a channel template. For information about the **Channel template** section, see [Creating a channel from a template](creating-channel-template.md).
   + Your organization might have deployed a MediaLive Anywhere cluster, in order to run channels on on-premises hardware. In this case, complete the MediaLive Anywhere settings. You must specify the channel placement group that the channel belongs to, and the cluster that this channel placement group belongs to.

     If you were involved in [designing the MediaLive Anywhere clusters](emla-deploy-design-cluster.md) in your organization, you should know which is the appropriate channel placement group and cluster. If you weren't involved in this design, you must obtain this information from the video engineer who was involved. 
**Warning**  
Don't arbitrarily choose a channel placement group and cluster. If you do, it's possible that the channel won't run because it will be assigned to a node that can't handle this type of input, or that future channels won't run, because you have overloaded the channel placement group.
   + In **Channel class**, choose the class. See [Channel class](channel-class.md).

     With a regular MediaLive channel, you can set up the channel as a standard channel or a single-pipeline channel.

     With a MediaLive Anywhere channel, you must set up the channel as a single-pipeline channel.
   + If you selected **SINGLE\_PIPELINE** for channel class, you can optionally configure **Linked channel settings** to set up this channel as a primary or follower channel for pipeline locking. See [Linked channels for single-pipeline channels](channel-class.md#linked-channels).
   + In **Input specifications** and **CDI input specifications**, complete the fields to match your input. See [Input specifications settings](input-specification.md).
   + In **Output delivery**, set up the channel to deliver output via the public internet or your Amazon VPC. 

     With a regular MediaLive channel, you can set up in either way. For information about delivering via Amazon VPC, see [Delivering outputs via your VPC](delivery-out-vpc.md). 

     With a MediaLive Anywhere channel, you must set up the channel to use the public internet.
   + In the **Tags **section, create tags if you want to associate tags with this channel. For more information, see [Tagging resources](tagging.md).
