Can I ask how much buy in these have from the archives community.

So for example, if I search The National Archives site in the UK, I can find no mention of it, despite The National Archives claiming to be front runners in the preservation of digital material.

Are we talking here about one input of many from the archives community, or are we talking about a proposal that already has consensus internationally in the archives community?

Subject: [dispatch] Standardization of FFV1, Matroska


MediaConch: Media Conformance Checker (maintained by MediaArea and funded by PREFORMA*) is looking to solicit feedback from the IETF for proposed standardization of FFV1 and Matroska.

The current (and under development) specifications for FFV1 exist here:<>
and here for Matroska:<>

The goal of the PREFORMA project is to address the challenge of implementing good quality standardised file formats for preserving data content in the long term. Our objective in regards to standardization FFV1 and Matroska is to improve the sustainability factors for both formats including disclosure, credibility, and transparency while also creating a mechanism to clarify, authoritatively, the intent of the specifications. After careful research into past IETF work (in particular Daala and Opus), we are planning to prepare FFV1 and Matroska for submission to the IETF.

Our preparations are not yet at the stage where we have created a formal draft or submission for the IETF.  Before we proceed, we'd like to engage the IETF community in discussion of the specifications and suitability for IETF.

Briefly, FFV1 is a lossless video codec and Matroska is an extensible open source media container.   Matroska is the base of WebM, and WebM is the preferred container for VP9, which has a draft RFC:<>

Work on FFV1 is coordinated through the GitHub and the ffmpeg-devel mailing list ( Work on Matroska is coordinated through GitHub and the devel mailing list (

We look forward to hearing your thoughts and suggestions.

Best wishes,

Tessa Fallon, on behalf of MediaArea
