Change the reserved unit type


A Media Services account is associated with a Reserved Unit Type, which determines the speed with which your media processing tasks are processed. You can pick between the following reserved unit types: S1, S2, or S3. For example, the same encoding job runs faster when you use the S2 reserved unit type compare to the S1 type.

In addition to specifying the reserved unit type, you can specify to provision your account with Reserved Units (RUs). The number of provisioned RUs determines the number of media tasks that can be processed concurrently in a given account.


RUs work for parallelizing all media processing, including indexing jobs using Azure Media Indexer. However, unlike encoding, indexing jobs do not get processed faster with faster reserved units.
