MMC Asset Manifest

Partners delivering component source packages to Prime Video must include an asset manifest. Prime Video supports the Media Manifest Core (MMC) specification. MMC is an industry-standard XML schema designed by MovieLabs. Documentation on this specification and example files are on the MovieLabs website.

Prime Video supports a subset of the MMC spec. The complete set of available MMC fields along with notes regarding Prime Video usage is provided in the MMC Field List section. When delivering MMC asset manifest files, they are subject to the file naming rules.

Identifiers in MMC

MMC references a variety of IDs throughout the manifest. To ensure that identifiers are globally unique and to allow for manual exception handling, please use the following Uniform Resource Identifier (URI) structure within MMC submissions. Additional information is on the MovieLabs website.

Identifiers use the following URI structure. Examples are provided in the next section.

<namespace>:<type>:<scheme>:<SSID>:<Additional Information>

  • <namespace> defines the scope of the identifier. Throughout the MMC, the namespace is always md.
  • <type> is the type of identifier, i.e. what is being identified. Examples include audtrackID, vidtrackID, PresentationID, etc.
  • <scheme> identifies the scheme of the ID provided in the SSID. Amazon accepts two schemes. The scheme used is determined by what kind of ID is provided to Amazon to identify content:
    • eider-x indicates that the ID provided is an EIDR with additional information following the EIDR.
    • org indicates that the ID provided is unique identifier determined by the partner (not an EIDR).
  • <SSID> is the content identifier. It's either an EIDR or the unique ID submitted by partner. If the org scheme is used, then the partner’s PartnerAlias must precede the ID provided, as mandated by the MMC spec.
  • <Additional Information> is where more information can be submitted. If the eidr-x scheme is being used, then the partner’s PartnerAlias must immediately follow the EIDR. Additional information may follow that. Additional information is sometimes required in order to make the identifier unique. For example, information contained in the Additional Information section (in red text below) is what makes the two IDs below unique:
    • md:audtrackid:eidr-x:8011-8DCB-38E0-BF71-83D2-U:amazon_studios:feature.audio.en
    • md:audtrackid:eidr-x:8011-8DCB-38E0-BF71-83D2-U:amazon_studios:feature.audio.fr

Identifier Examples

Eidr-x Identifier Example

The eidr-x scheme should be used if you are delivering EIDR numbers to identify your content. Prime Video prefers EIDR numbers to identify titles. When providing EIDRs to Prime Video, you must omit the EIDR prefix, which is everything prior to the slash character (e.g., "10.5240/"). Submit only the unique suffix and check digit (e.g., XXXX-XXXXXXXX-XXXX-XXXX-C). The Prime Video-supplied Partner Alias is appended after the EIDR, separated by colons.

Diagram of Eidr-x Identifier example string

Org Identifier Example

The org scheme should be used if you are delivering unique IDs that are not EIDRs to identify your content. An example is below. Note that the Prime Video-supplied Partner Alias is provided immediately preceding the title ID.

Diagram of ORG Identifier example string

Sections of the Manifest

Inventory

The Inventory section of the MMC includes details about all of the assets (video, audio, timed text, and images) being delivered as part of a component source package.

Presentations

The Presentation section of the MMC indicates which assets delivered as part of a package should be played together. For example, if a package includes two video assets (one for the feature and one for the trailer), five audio tracks (four for the feature and one for the trailer), and eight timed text assets (all associated with the feature), there would be two Presentations associated with that inventory. The first would be for the Feature, and would include one video asset, four audio tracks, and eight timed text assets. The second presentation would be for the trailer, and would include one video track and one audio track.

Playable Sequences

The Playable Sequence section of the MMC provides details about Presentations that are intended to be played together and their sequence ordering. These entries aren't required.

Picture Group

A Picture group is a selection of images from the inventory that are referenced by an experience. Prime Video currently supports only one image per experience, so only one image from the inventory should be referenced in each picture group.

Experiences

The Experience section of the MMC groups Presentations and/or Playable Sequences along with Picture Groups to define the customer experience. For example, a single Experience could be composed of a Playable Sequence that contains a Rating Card, Feature Presentation, and a Dub Card.

ALID-Experience Mapping

A Logical Asset ID (ALID) is used to match the avails to the content. The ALID-Experience Mapping section of the MMC relates ALIDs from the EMA avails to the Experiences associated with that content.

MMC Field List

The table below summarizes the available MMC fields along with Prime Video specific notes.

The Field Name column lists MMC fields and indicates the hierarchy of the fields through indentation. Attributes for fields are indicated by the "@" symbol. Accepted Values lists the acceptable values or indicates the type of value expected for each field. If left blank, it indicates a string is acceptable. Inputs are limited to UTF-8 characters. Prime Video Usage indicates whether the field is required, optional, or not used by Prime Video.

The following table and notes are in addition to the documentation and definitions provided by MovieLabs. Should any conflict occur between the two, notes and guidelines provided below shall be considered definitive for deliveries to Prime Video.
