# Create media processing sets

Media [processing flows](https://doc.sitecore.com/ch/en/users/content-hub/create-processing-flows.html "Create processing flows") determine how assets are processed. A media processing set contains multiple processing flows. For example, the **Content** media processing set contains the main media processing flow that an asset goes through in a simple create and review flow.

To create media processing sets:

1. On the menu bar, click **Manage** :mdiCogOutline:.
2. On the **Manage** page, click **Media processing**.
3. On the **Media processing** page, click **New set**.
4. In the **New set** dialog, enter a name for the new set.
5. If you want the processing set to apply by default and run on each processing job, turn on the **Auto-run** switch.
6. Click **Create**.

> [!note]
> If you don't enable **Auto-run**, you can manually trigger the creation of renditions by configuring the media matrix set to use the *mediaMatrixToAsset* relation. This triggers a processing job that generates renditions based on this set. You can automate this by creating a custom action, script, or trigger based on the automatic processing job creation.
