    • SMPTE / Interop standard convention (naming, …)
    • Integrity (MIME type, size, hash) of all assets
    • Foreign file identification
    • XSD Schema validation for XML files (VOLINDEX, ASSETMAP, CPL, PKL)
    • Digital signature validation (CPL, PKL)
    • Intra / Inter Reels integrity and coherence
    • Metadata match between CPL assets and MXF headers
    • Re-link VF / OV
    • Picture tests : FrameRate, BitRate, …
    • Sound tests : Channels, Sampling, …
    • Subtitle : Deep inspection of Interop and SMPTE subtitles
  • DSM / DCDM Checker : basic image file sequence validation with some specific rules.


Usage

ClairMeta can be used as a general command line tool as well as a python library.
