Matroska.org

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.

Happy birthday @MatroskaOrg

#MKVToolNix v72.0 has been released with important bug fixes. @mosu/109336666169801173" target="_blank" rel="nofollow noopener">fosstodon.org/@mosu/10933666…

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

RFC 9043: FFV1 Video Coding Format Versions 0, 1, and 3 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-devel…

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

@cconcolato That sounds like an issue with the muxer used by Shaka Player. Maybe one Cluster per frame ?

"Take a 180p video for example, if the bitstreams of video and audio are around 100kbps, the size is about 102kbps after converted to fMP4 DASH format. But when we convert it to Webm DASH format, the size is about 120–130kbps" is it true? blog.hotstar.com/vp9-encoding-j…

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! ££££££££££££

Looks like we are out of quarantine.

SMPTE is providing some of the standards and publications for free for a limited time. smpte.org/free-standards…

@Chiclemolesto @RetoKromer There's an active group of people working on standardization at IETF. That's where most things happen regarding the format itself.

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

@Art1Pirat If it's two separate films it may be better to have two files. But Matroska doesn't use the concept of fps so you can have consecutively multiple fps. Only the timestamp of each frame is useful.

@MatroskaOrg Btw, is it possible to encode two different fps in one matroska file? Background: digitize a filmroll as one file, but in filmroll there are two movies, first one with 18fps, second with 24fps. Possible, right? How would this mapped in Matroska? Thx.

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.
