Sustainability factors; AdoptionModest adoption in heritage repositories. The City of Vancouver Archives uses FFV1 encoded video wrapped in the Matroska container, as discussed briefly on the archives' blog. This implementation is connected to the open source Archivematica project, whose Wiki lists Matroska-wrapped FFV1 video and LPCM audio as one of its preservation formats. Matroska also plays a critical role in the WebM open media project. [...]
