LoC's RFS lists IMF (MXF essence, CPL, packaging XML) first for file-based final video; the Academy forum describes IMF as a wrapper in significant industry use, notes an LoC MXF archiving subset (SMPTE RDD 48) and IMF App 5 ACES (ST 2067-50); FIAF 2019 found only CNC and LoC requesting a mezzanine on deposit, with CST recommending IMF (ST 2067-40) as mezzanine. Evidence of IMF as an actual long-term archive master remains thin.
