The adoption of the Digital Cinema projection has opened new opportunities for the distribution of films. The digitization of commercial film collections and film heritage is developing rapidly. Up to now there has been no specific format for the interoperable exchange and conservation of cinematographic works with the highest required quality.

ETSI’s Centre for Testing and Interoperability (CTI) organized the 3rd Cinema Mezzanine Plugfest. This event was held from 1 to 2 March 2017 in Erlangen, Germany, with the support of the Commission Supérieure Technique de l’image et du son (CST) and hosted by Fraunhofer Institute for Integrated Circuits IIS. This event focused on assessing the interoperability of Cinema Mezzanine format based on SMPTE® ST 2067-40:2016 IMF App#4 – Cinema Mezzanine (published standard - see "Related documents" tab).


In February 2011, at the request of the French Centre National du Cinéma et de l’Image animée (CNC), the Commission Supérieure Technique de l’Image et du Son (CST) started to work on the technical recommendation CST-RT021. The goal of this recommendation is to ensure that the commercial exploitation of digitized cinematographic works on modern digital distribution channels is made possible with the required quality.

The first version of the CST-RT021-MFFS specification has been published alongside the CST-RT021 recommandation in 2013. It has been designed to be consistent with current developing standards, specifically the SMPTE Interoperable Master Format (Technical Committee 35 PM). The specification has been proposed to SMPTE Technical Committee 35PM (“Package management”), and is since September 2016 a SMPTE published standard.

The expert group led by CST is proposing that film laboratories, audio-visual equipment manufacturers and all interested parties participate in a Plugfest to test the specification implementations, as well as proposing improvements for the future revisions of the document.
This event will focus on assessing the interoperability of Cinema Mezzanine format based on SMPTE ST 2067-40:2016 IMF App#4 – Cinema Mezzanine.
