Proprietary “mezzanine” Formats

• History

– Exchanging Master elements in the form of tapes

– Evolution to file-based exchange but with various proprietary formats

– Multiplicity of Video/IT media distribution platforms


Proprietary “mezzanine” Formats

• Two main factors

– Containers (ex: QuickTime MOV which has never been standardized)

– Codecs (ex: Apple ProRes requiring Mac platforms)


IMF: General Presentation

• Standardization

– By SMPTE: 35PM-50 WG on IMF

– Involvement of most major actors of the media market (manufacturers, right-holders, etc.)

– Standardization status: approximately 90%
