MKVToolNix v83.0 released

[Nejiro]

Greetings to all, I am new to this forum and I apologize if I use a translator, I use MKVToolNix on Ubuntu 20.04 lts, I have some 1: 1 bluray in which I removed the various languages that I do not need by transforming the m2ts file into mkv, all it works well but I noticed with mediainfo that the bitrate of the video on the mkv file is lower than the m2ts, so I lose quality on the mkv file compared to the m2ts? Or does mkv remove things that are not needed without me losing quality?
Thanks

[videoh]

Overhead for an M2TS is higher than for MKV. The actual video is not affected in any way.

[Nejiro]

Perfect, thank you very much for your reply, so with an mkv file you won't lose anything, that's what I wanted to hear ......

[Nejiro]

Excuse me another question, when I create mkv files with Handbrake I have the possibility to insert in appropriate spaces plot of the film, director, year etc ... with MKVToolNix is it possible to do it? I can't find where to insert this data .....
Thanks

[videoh]

One possibility:

MKV gurus here may know more about it.

And, oh, welcome to the forum!

Such things could be preserved with Matroska Tags.
MKVToolNix has no Tags editor you could try chapterEditor for this task.

[Nejiro]

I imagined there wasn't a tag editor like on Handbrake, creating an html file I wouldn't know how ...
Thanks

[Nejiro]

Excuse me another question, I have an mkv file in which an audio track starts about 5 seconds behind the video, how can I synchronize them? I select the audio track and in the audio delay field I enter 5,000? I don't know how it should be inserted exactly the value 5000 or 5.000? If instead it is the opposite and that is that the audio is in advance I have to put the minus sign in front, that is -5000?
Thanks

The "delay/sync" functionality simply adds the number of milliseconds given in the box to all timestamps. So if audio is 5s behind your video you have to subtract 5s, which means: add "-5000" ms. So you enter "-5000".

Like others say, it's easy once you know how to tag MKV files. At first, you may feel XML files are difficult, but once you create your "template", you can just reuse the same file again and again, with just editing the tag values.

There is, however, one subtle, tricky aspect...
MPC and MPC-HC parse DESCRIPTION and show it as Description in Information (Ctrl+3).
MPC-BE parses the last COMMENT and shows it as Description.
Because of this, if you'd like to get a consistent result (for both HC and BE), set the last COMMENT identical to the global DESCRIPTION tag (as a workaround). If you only use a global tag file, this simply means COMMENT and DESCRIPTION have the same value in it. If you use par-track tag file(s) too, the COMMENT of the last tag file matters: e.g. if you have not only global.xml but also video.xml, audio.xml, and sub.xml and the track order is video audio sub, then COMMENT in sub.xml matters.

If you don't mind such minor detail (HC/BE compatibility) you can safely ignore this It's just a (weird) workaround for specific players, not at all required in the matroska specs.

I'm not sure what MKV supports and I doubt that what I want can be done, but perhaps someone less ignorant than me will pitch in.

What I want, and what a BD player does, is pair audio & subtitles in particular ways.

A particular BD movie has English dialog & French dubs. It has infrequent German dialog during scenes set in Berlin. If English dialog is selected (default), then German-to-English translation subs are automatic. If French dubs, then German-to-French translation subs are automatic.

Streams:
1 English audio
2 French dub
3 English subs
4 French subs
5 German-to-English translation subs for scenes in Berlin
6 German-to-French translation subs for scenes in Berlin

Playback of BD disc (e.g., PowerDVD):
1 (+5 automatic) -- part-time translations only
2 (+6 automatic) -- part-time translations only
1 (+5 automatic) + 3 -- full-time English subs & translations
2 (+6 automatic) + 4 -- full-time French subs & translations

Playback of MKV remux (e.g., MPV):
1 -- no subs, no translations
2 -- no subs, no translations
1 + 3 -- English subs but no translations
2 + 4 -- French subs but no translations
1 + 5 -- translations but no English subs
2 + 6 -- translations but no French subs

Is there any way to pair 1 & 5 and 2 & 6 (as though forced subs) so that an MKV remux duplicates the behavior of a BD disc player?
1 (+5 automatic) + 3 -- full-time English subs & translations
2 (+6 automatic) + 4 -- full-time French subs & translations

Thanks,
Mark.

The MKV specs don't offer the possibility to bind any specific audio track to a specific subtitle track (or vice versa). I vaguely remember something about a possibility using editions though I think players didn't support it anyways so ...


(Back in the day "Haali's Splitter" offered support for non-spec "TRACKSETEX" to offer such pairings but I don't know if there is any player support outside of the deprecated Haali Splitter.)

Is there a way to delete a language from the ISO list? Church Slavic bla bla bla is so long the right-hand panel in the multiplexer is stretched unnecessarily. I will never ever use it among a few others I could trim.

[stax76]

Dotnet just calls this Church Slavic. Maybe somebody finds the staxrip approach interesting:

Thanks for the info. -- Mark.

PS: I found the MKV specification, but github is a show stopper. I searched for MKV editors, but turned up only video editors.

Is there an IFOEdit-style editor for MKV that will at least allow me to see into an MKV and see/copy metadata?

Yeah, so I'm sure it can be configured somehow.

The GUI's info tool and header editor give you access to pretty much all of that.

That only works if I select the tickbox to "only include often used in list" but that defeats the point of an often used list.

Not really, it just allows you to use the selections in two different modes, depending on what you prefer: either the full list with certain entries located at the top or only those entries you tend to use over and over. Most people I talk to prefer the latter.

Don't get hung up on the name.
