For more information, see the\n[Media assets](/transcoder/docs/locations#media-assets) section of the Locations\npage.\n\n1. Create a Cloud Storage bucket and configure it as follows:\n - Set the storage class to `S` (Standard).\n - Set the storage location to the following: `US` (United States).\n - Replace \u003cvar translate=\"no\"\u003eBUCKET_NAME\u003c/var\u003e with a unique bucket name. Don't include sensitive information in the bucket name because the bucket namespace is global and publicly visible.\n\n ```bash\n gcloud storage buckets create gs://BUCKET_NAME --default-storage-class STANDARD --location US\n ```\n2. Click **Create Folder** and enter a name to create a folder in which to save the encoded video outputs.\n\nMore information\n----------------\n\nReceive [Pub/Sub notifications for job updates](/transcoder/docs/how-to/create-pub-sub)\nfrom the Transcoder API."]]
