SMPTE Presentation
7 December 2010
The IMF [Interoperable Master Format]
What are we trying to solve? The Problem for Distribution Servicing
Version explosion [ex. (32 language versions) x (codec of the month club)]
Move from tape based to file based
Too many wrapping and file formats to choose from (ex.QT, MXF, Pro Res, dpx, Cineon, MPEG)
The storage of multiple flattened file versions
Asset management nightmare

SMPTE Work Work cuts across many TC’s
We propose two serialized work levels for IMF Basic Level
Leverage existing standards Fast Track (Completion around Summer/Fall 2011)
Extended Level Creation of New Standards More long term (Completion around Fall/Winter 2011/2012)
Harmonization AS-02 3D Home Master ACES
