Project Overview

MediaConch is currently being developed by the MediaArea team, notable for the creation of open source media checker software, MediaInfo. Furthermore, the MediaArea team is dedicated to the further development of the standardization of the Matroska and FFV1 formats to ensure their longevity as a recommended digital preservation file format.


All software and source code developed by MediaArea during the PREFORMA project will be provided under the following two open source licenses: GNU General Public License 3.0 (GPLv3 or later), Mozilla Public License (MPLv2 or later).

All open source digital assets for the software developed by MediaArea during the PREFORMA project will be made available under the open access license: Creative Commons license attribution – Sharealike 4.0 International (CC BY-SA v4.0). All assets will exist in open file formats within an open platform (an open standard as defined in the European Interoperability Framework for Pan-European eGovernment Service (version 1.0 2004)).


This project has received funding from PREFORMA, co-funded by the European Commission under its FP7-ICT Programme.
