The foundation of Matroska is now officially @rfc 8794. Thanks to everyone who contributed to make this real over the past decade or two. Especially the authors @robUx4, @dericed and @MoritzBunkus.

And it's ready! 📼❤️📜 The FFV1 lossless video encoding format (versions 0, 1 & 3) is now officially documented as an Informational RFC by the @IETF as RFC9043. 👏🥳 Lots of great work by lots of great people on this. #ffmpeg #ffv1 #openstandards rfc-editor.org/info/rfc9043

Beta-time: I've just released Mp3tag v3.06e which adds editing cover art for Matroska MKA/MKV 🖼️ This way editing image attachments in the @MatroskaOrg container becomes a breeze and is integrated with all the different tag sources of Mp3tag 🙌 Enjoy! community.mp3tag.de/t/mp3tag…

It looks like 20TB of #FFV1 @MatroskaOrg this week but thanks to @MediaArea_Net #RAWcooked the DPX are also preserved as MKV... so 28 TB of FFV1 MKV ingested this week in @BFI National Archive

Spoiler alert: there's a new #FFV1 standardization status! "Approved-announcement to be sent" 👀 "Submitted to IESG for Publication" 🥰 🎞️📼🚀✅ #lossless #avpreservation & #ietf #ffmpeg

I kind of miss the days of #digipres drama where MOV and MKV were battling for supremacy in @BFI National Archive. Game over, #FFV1 @MatroskaOrg won... even those DPX are FFV1 MKV, thanks to @MediaArea_Net #RAWcooked. MPEG-TS are plentiful from off-air telly, but they’re so wee!

Also just thought - without #FFV1, all these Matroskas would be 30TB not 15. All hail FFV1 Matroska, the power team for 15TB per day data storage savings! ££££££££££££

Now @MatroskaOrg is blocked. Let's see if they accept this

Yes, very much. YouTube is actively using the technology for example. A lot of public and private archives worldwide are turning to Matroska as well.

Look what happened when I was busy dealing with other things... @MatroskaOrg reached critical mass... even the ‘DPX’ here are also MKVs, #RAWCooked by @digitensions

I’m no epidemiologist and no public health expert. I do believe passionately in science and also in #Factfulness. This man is the global authority on the spread of disease. If you are a leader (in any capacity) watch this. If you are not, watch it too.

So 6.3 TB data size reduction. But of course we store two instances, in two data tape libraries, so it’s really 12.6 TB storage cost saving. LTO6 yields 2.8 TB usable capacity, so in one day, using #FOSS, we saved 4 LTO data tapes. If we repeat each day, one month = 120 tapes. 😍

Today the IETF cellar working group released version 17 of EBML (the binary XML format on which Matroska is based) & version 12 of FFV1 (a lossless video encoding). #openstandards #openmedia ietf.org/id/draft-ietf-cella… ietf.org/id/draft-ietf-cella…
