In order to claim uploaded videos, what is the first step in the Content ID workflow for a partner, after verifying rights?

The first step in the Content ID workflow, after verifying rights, is to deliver reference material to YouTube. This material, such as audio or video files, forms the basis for Content ID to identify matching content across the platform. Without this reference material, Content ID cannot function. "View and manage claim settings" comes later, after reference material has been ingested and Content ID is actively matching. "Convert material into proprietary video format" is incorrect as YouTube accepts standard video formats, and there's no proprietary format conversion required. "Flag uploaded content that may infringe on rights" describes a user-driven reporting mechanism, not the automated Content ID system for rights holders.
