<?xml version="1.0"?> <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
