Robust, Repeatable and Interoperable Workflows through IMF Output Profile Lists

摘要

The SMPTE IMF (Interoperable Master Format) has, over the past couple of years, been adopted by content owners (studios and broadcasters) in numerous applications ranging from archival to distribution servicing. The key characteristics of variable composition (via Composition Playlists) and packaging provide proven economy in scaling of versions. An additional feature of the IMF framework, the Output Profile List (OPL), provides the foundation of robust and interoperable workflows through the use of standardized media processing macros (operators) ensuring identical output regardless of systems or facilities. This presentation details how standardized as well as customizable OPL operators can be applied to construct a universally portable processing pipeline for content servicing.
