Local use

LC experience or existing holdings	As of November 2021, the National Audio-Visual Conservation Center (NAVCC) has ingested several hundred ffv1/mkv files. These files were received from CUNY-TV through the American Archive of Public Broadcasting and the Library will receive many more of these files through the AAPB in the future.
LC preference	FFV1 codec in the Matroska container is a 'preferred' format in the Recommended Formats Statement (RFS) for Video -- File-based Improved support for timecode, as opposed to timestamps, is still in development as is support for multi-planar and 3D videos.
