The purpose of this document is to facilitate and define Warner Bros. Discovery’s requirements for receiving Standard Dynamic Range (SDR) Promotional Content. This specification establishes the compositional and technical requirements for all aspects of delivery to which content providers must comply. Compliance with these requirements ensures successful deliveries into the Warner Bros. Discovery Media Supply Chain (MSC).

This specification is not intended to provide guidance on delivering High Dynamic Range content to Warner Bros. Discovery. For additional Contribution Specifications covering these deliveries please reach out to your Warner Bros. Discovery Contact.

Promos can be delivered via the content portal or via automated content delivery (ACD) through Aspera. If opting for ACD delivery, MMC metadata requirements must be met.

Quality Requirements

It is Warner Bros. Discovery’s intent to acquire the highest quality masters that preserve the original artistic intent while providing a premium viewing experience to the consumer. To meet Warner Bros. Discovery's perceptual and measured quality standards content MUST conform to the specifications outlined in this document.

Please speak with your Warner Bros. Discovery contact if your highest quality digital master does not meet the quality standards defined in this specification or if you have questions related to this specification.

Photosensitive Epilepsy Testing

Photosensitive Epilepsy (PSE) impacts a viewer population who may be prone to seizures caused by flashing images on a screen. Warner Bros. Discovery requires that all content follows the guidance for the reduction of photosensitive epilepsy as defined in ITU-R BT.1702-2.

Warner Bros. Discovery strongly recommends that providers use a “Harding Flash & Pattern Analyzer” on all content prior to delivery to ensure it meets these recommendations. Content found to be outside these test parameters will be rejected and will require redelivery.

The Digital Production Partnership has provided a list of approved tools to assist in PSE testing.

  1. Master Media File

Naming Convention

Portal

If the promo is being uploaded to Portal, it must follow the below naming convention:

"<"name/title">"_CID"<"CID">".mov

There is no limit on the length of the CID. “CID” is not case sensitive. It can be uppercase or lowercase. Portal looks for “_CID"<"CID">"” within the file name. The name before the underscore is ignored for the purposes of Portal.

Example

ExampleName_CID051022.mov

Guidelines

  1. Filename must not include spaces or special characters, e.g. ~ ! @ # $ % ^ & * ( ) ` ; < > ? , [ ] { } ’ ” |. With the exception of – (dash) and _ (underscore).
  2. Underscores must be used to separate categories within filename.
  3. All filenames must contain a file type extension and must be lowercase. Uppercase extension will result in an invalid content delivery.
  4. Filename category should use CamelCase: multiple words joined together with the first letter of each word capitalized, e.g. Search Party -> SearchParty.
