What is a media reserved unit? What benefits do I get if I use it?
Adding media reserved units to your account ensures that multiple files are processed concurrently, and changing the type of the media reserved unit affects the speed at which the files are processed. For example, if your account had three media reserved units of type S1, then up to three files will be processed concurrently. By changing the type of reserved unit to S3, each individual file processes faster. See our documentation for more information.
