This document outlines the required audio, video, and structural specifications of materials submitted to the Clearcast Library. It contains a breakdown of all the elements required for a material to pass QC and documents what specifications are tested at each QC step.
This document is intended as a guide only for the export of content from Media Encoder. Suppliers should perform their own encoding tests and QC to verify final settings achieve the required specification and level of quality.
PLEASE NOTE: We require either a 0 second or 5 second freeze at the end of all materials.
