Asset Manifest

Asset manifests serve two main purposes.

They provide metadata describing the technical assets delivered (such as asset type, language tags, resolutions, frame rates, etc.).
They identify which assets are intended to be packaged together.

There are two supported manifest formats in Classic territories.

The Amazon Simple Asset Manifest
File Naming Convention

Each Aspera delivery account only supports one of the two manifest options, but not both simultaneously. Specifics on how to deliver to each option are as follows.

Amazon Simple Asset Manifest

The Amazon Simple Asset Manifest allows partners to deliver an XML file with asset metadata. Audio descriptions and HDR mezzanines must be delivered via XML Metadata. The Simple Asset Manifest includes the ability to use non-conformed file names, provide technical asset details such as frame rate and Drop/Non-Drop Frame values for timed text assets, and the association of a title identifier to each asset. This manifest can be included in the same file as the XML title metadata or be delivered as a separate file. When an asset referenced in the manifest needs to be redelivered, Prime Video requires the new asset file to have a different file name than what was previously referenced. Prime Video prefers you amend the file name with an "R1," "R2," etc. Example files for each of these options can be found in the Sample Files. When delivering Amazon XML files, they are subject to the file naming rules.

If you are currently delivering to File Naming Convention, migration to delivery via the Simple Asset Manifest requires Prime Video to make manual configuration changes to your partner delivery account. If you want to use the Amazon Simple Asset Manifest, please contact your Operations Account Manager for details.

File Name Convention

If you prefer to not utilize the Simple Asset Manifest to deliver to the Prime Video Classic territories, you must follow the File Name Convention. Prime Video uses the hyphen ("-") as a delimiter between values within the file name of the provided asset. This naming convention must be followed exactly. Failure to do so will result in assets not matching to the correct title or processing correctly.

File Naming Convention: [PartnerAlias]-[UniqueID]-[ContentType]-[AssetType]-[LanguageCode]-[Territory].xxx

Example: Titan-ExplosionsMovie-Full-Mezz_HD-en-US.mpg

The PartnerAlias and UniqueID must match exactly those used in the metadata and avails for that title. Each section of the file name is separated by a hyphen ("-"), not an underscore ("_") or other punctuation.
No spaces are allowed in file names. Underscores ("_") can be used to separate words within a single section of the file name, but please be careful that you are not using an underscore when a hyphen ("-") is required instead.
Metadata and avails files don't need to follow File Name Convention, but to help track them for review and troubleshooting, it is recommended to name them with keywords relating to your organization in addition to other identifying information.

File Name Sections

In the File Name Examples table below, descriptions are provided for each of the specific fields required in each asset file name. In the examples provided, brackets ("[" and "]") are used to delineate required components and must not be included in the file name. They are only included in these examples to increase legibility.
