One of the things that is interesting doing mass encodes is verifying all of the little things that can just mess everything up. If you're pulling in stuff like 3rd-party subtitles, then you have to verify the timing of the subtitles and adjust as necessary. Even better, if those are SubStation Alpha subtitles, you have to verify if the style fonts get added as attachments to the MKV file.

And if it's across something like a TV show, you definitely need to do this for every episode. If there _is_ an issue, you get to fire up Aegisub and try to track down the exact offset you'll need and either correct that via Aegisub or when you inevitably have to remux via `mkvmerge`/MkvToolnix.

The smallest release of MKVToolNix ever is out, v97, with just one change. But still, have to keep up with the schedule, I guess 😁 Note to macOS users: I've decided to stop offering macOS binaries in the second half of 2026 due to Apple sunsetting support for the Rosetta x86-to-ARM translation technology and my build process only producing x86 binaries. https://www.bunkus.org/2026/01/2026-01-02-mkvtoolnix-v97-released/ #MKVToolNix #Matroska

Free Software that I rely on. One per day.

Day 18:

MKVToolNix

This is a tool kit of utilities, including a GUI front end, for manipulating Matroska streaming multimedia files (usually "MKV" or "MKA" files).

The Matroska container format allows for multiple audio, video, and text streams, which means you can encode a video with multiple options for audio and subtitles (as well as alternate video tracks).

It also supports setting up "Chapter" marks.

A must-have for authoring and checking complex videos for streaming and download use.

Any matroska expert here? I notice while re-muxing an mp4 file with packet re-ordering to mkv that ffmpeg logs this when decoding the result mkv file:
[h264 @ 0x85d088380] Increasing reorder buffer to 2
This seems to be related to the "video_delay" in ffmpeg. The mov demuxer seems to derive the 2 from the ctts box. Bug in matroska demuxer? no element stores this? or would have to derive the same thing from reading all blocks for the video track which would be expensive?

@tauon Tenacity already supports #MIDI right now in a limited capacity. For the new project format, we would not include MIDI support as we would have to figure that out. We still haven't thought that through, but it could be possible. (Edit: so yeah, it'd be more so a 'yet' right now).

Unless #Matroska already supports MIDI. Then that's a different story...

The idea behind this new format is simple: what if we returned to the older AUP format, but we put everything in a binary #XML representation? After all, an #AUP project is just an XML file with a directory containing block files, so why not merge all this data in a binary XML representation?

It turns out we can, and what better format to use than #EBML? #Matroska uses it, and since it's a container that supports audio, we can use it as a starting point for our new project format.
