<policy type="or" name="SLUB Policy for MKV/FFV1v3, retrodigitized film 16mm" license="CC-BY-SA-4.0+">
  <description>SLUB related policy to test that the video file is suitable for archiving purposes.
    This checks if a MKV/FFV1v3 fulfills the needs for 16mm retrodigitization (also Super16, Normal16,…):
    - Container format is Matroska with error detection (CRC)
    - Video format is FFV1 with error detection (CRC) and with Intra mode (each frame is independent)
    - Audio format is PCM (unfortunately it can not contain error detection) or FLAC (it has CRC by design)
    This policy is based on:
    - Example MKV FFV1 digitization policy.xml
    - Video file is MKV + FFV1-Intra + PCM or FLAC with CRC32 everywhere.xml
    If there are any policy violations or suggestions, please send an email to langzeitarchiv@slub-dresden.de
