PREFORMA (a Pre-Commercial Procurement (PCP) project co-funded by the European Commission under its FP7-ICT Programme) is a project to address the challenge of implementing good quality standardised file formats for preserving data content in the long term. The project selected several audiovisual formats to focus on. MediaArea (the developers of MediaInfo) submitted a successful proposal focusing on three of their selections: FFV1, LPCM, and Matroska. As part of the proposal we noted that Matroska and FFV1 have not undergone a formal standardization process and wrote up these plans to attempt to facilitate this. Under this project MediaArea will develop MediaConch, an extensible, open source software project consisting of an implementation checker, policy checker, reporter, and fixer that targets preservation-level audiovisual files for intended use in archives and memory institutions.

This talk will discuss strategies for developing tools for conformance checking, the role of open source development in archival workflow, and the state of standardization efforts for the lossless video codec, FFV1, and open audiovisual container format, Matroska.
