Overview

Release: 1.2 | September 23, 2026

Welcome to Warner Bros. Discovery Content Partner Hub. This site provides support and reference materials to guide Content Partners through the initial onboarding process to Warner Bros. Discovery Media Supply Chain. You will also find the most up-to-date technical specifications, metadata templates, and samples to support the ongoing, accurate and efficient delivery of media, images, and metadata.

Prior to delivering content to Warner Bros. Discovery, Content Providers must be onboarded to one of the two supported methods.

Materials Exchange: A user interface to upload media into Warner Bros. Discovery's media supply chain.
Automated Content Delivery (ACD): High volume delivery via Aspera P2P, utilizing MovieLabs Media Manifest Core (MMC) to provide technical and configuration metadata.

Please work with your Warner Bros. Discovery Business and Operations contacts to determine the delivery method best suited for your content volume and technical capabilities. Once determined, review either the Materials Exchange or Automated Content Delivery guides to initiate the onboarding process.
