Manifest Manipulation can be optionally added

This functionality lets you enhance your end users' viewing experience by individualizing video quality to their device's capabilities.

You can add the Manifest Personalization behavior to a rule in your AMD configuration. When a request is sent to your hostname that matches the criteria set for this rule, the settings you've defined for Manifest Personalization are used to generate a manifest "on-the-fly." This manifest determines the appropriate video quality content for the requesting device.
