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%
