Guidelines: MXF Sample Files

On behalf of the FADGI AV Working Group, the Library of Congress contracted with AVP and their subcontractor EVS, first Product Development Manager ValĂ©rie Popie and later Engineering Manager Nicolas Bernard, to create a set of graded sample files based on the MXF Archive and Preservation Format Registered Disclosure Document, known as SMPTE RDD 48. The sample files were reviewed by Oliver Morgan of Metaglue and Cube-Tec. 

  • Golden files include most - but not all* - of the technical components detailed in RDD 48. The components follow the defined rules and the files are well-formed and valid.
  • Silver files are similar to Golden Files in their composition except they deviate from the defined rules in RDD 48 in minor ways.
  • Copper files include more significant deviations from RDD 48.
  • Lead files contain fatal errors that that compromise the integrity of the conformance to RDD 48,

The sets of sample files are to faciliate ongoing implementation of RDD 48 and they are not intended serve as reference (conformance) files. It is important to note that the silver, copper and lead files contain known errors and are not conformant to RDD 48. They are included here for those interested in issues related to format validation and testing. FADGI is sharing them with the wider community to solicit feedback on the structure and validity of the files as well as the feasibility of complying with RDD 48. Interested parties are encouraged to communicate their findings and comments via the FADGI comment form or with the leader of the FADGI AV team (Kate Murray, kmur@loc.gov).

*Constraints of time and other resources limited the degree to which this set of samples represents the entirety of RDD 48. Users should be aware that this set of samples were "hand made" and do not represent the output of a factory-production system.
