Presentation made at The Reel Thing XXXVIII, 18–20 August 2016 in Hollywood, California, United States of America.

Abstract

IETF’s CELLAR Group is currently standardising the binary format EBML, the Matroska container, the FFV1 video codec and the FLAC audio codec. This presentation starts with a brief summary of the recent Berlin Symposium on those topics. The main focus will show how archives can use Matroska and FFV1 not only for the preservation of video streams, but also of single image RGB content, like DPX and TIFF, which may be an alternative for small archives.
