mkvmerge already does its best trying to recover as much data as possible. The message "Still resyncing…" means that it cannot find valid Matroska cluster IDs in the data. Basically there is no valid data left to recover.

To me it looks like an incomplete download, e.g. you started downloading via a BitTorrent client which pre-allocates the space, but it only the first part was actually downloaded. The rest of the file's allocated space is just garbage.

The MKVToolNix package contains a command-line only tool mkvextract for extraction. The MKVToolNix GUI doesn't have functionality for this yet, but it is on the TODO list.

There are third-party GUIs for mkvextract available, see e.g. the MKVToolNix links page.

So is there a "one-size-fits-all" solution :-)

No, not really.

Does mkvtoolnix proprerly handle the A/V sync issues that sometimes happen with seamless branching blurays?

Makemkv always removes 1 video frame as soon as the sync issue reaches 10ms to keep it properly in sync.

Does mkvtoolnix also do this, or is it still better to use makemkv to remux blurays?

Thanks.

[Mosu]

I honestly cannot answer that.

Have you given MKVToolNix a try? Did you encounter any problems with the sync in such a situation?

[Bigmango]

Is seamless branching support a planned feature for mkvtoonlix?

So we can:

1. Have theatrical and extended versions of a movie in the same mkv (saving a lot of HD space compared to keeping 2 files)
2. Have multi-language video (i.ex sometimes the titles and some texts in movies are written in several languages)- -> Kodi (xbmc) already automatically switches forced subtitles on the right language to match the audio language (it makes 100% use of the mkv language tags ). With this feature it could also play the correct language titles and text parts in the videos.
3. Have multi-angle support (some movies like Start Wars have up to 6 or 7 angles).

This is imho definitely needed to bring mkv to the next level.

Thanks.

I am asking because I haven't tried it.

Ok, unless someone has the answer untill then, I'll try it next time I encounter this with makemkv.

I use my chapterEditor to prepare Bluray-disks and I get then a mtxcfg-file. So I can use MKVToolNiX-GUI for all BD's. I have a lot of multi-editions(seamless branching) BD's mux to mkv without sync issues.

I am floored. I just remuxed my Avatar Collector's Edition bluray and got an MKV with the 3 editions (Extended, Special and Theatrical). And only 40Gb instead of 100+Gb. Awesome.

VLC sees the 3 editions and I can switch between them in the menu. You are a genius.

But, when I load this mkv (which was created by mkvtoolnix with your chapter editor) in mkvtoolnix it only sees it as 1 video track (with single audio tracks) and doesn't see the 2 other editions the mkv contains.

@ Mosu:

1. Could you please have mkvtoolnix show some information that there are several editions in the mkv?
2. as we already have bluray playlist loading in mkvtoolnix, it makes sense to add this multi-edition selection feature directly into mkvtoolnix, so we have complete bluray seamless branching support in mkvtoolnix (with the new GUI, mkvtoolnix now looks like an "MKV Workstation". I think we can definitely see this feature going in there)?

This would also attract more player support (for title selection) as this ordered chapters mkv feature (in the mkv specs for many years) would become more used and widely known.

I, for one, have used mkvtoolnix for years and had absolutely no clue this even existed.

WHY isn't this HUGE mkv feature used everywhere? -> Because no one knows about it as mkvtoonlix isn't even showing this exists.

Many thanks.

One more question:

How do you demux, or extract / separate the multiple editions into separate mkv files if need be (for future safe keeping /availability of the separate editions)?

Neither mkvtoolnix nor gmkvextractgui sees the multiple editions contained in the mkv (they only see the first title).

[ndjamena]

I'm pretty sure they don't see any of the "titles", just the base streams that the titles are constructed from.

The "titles" are in the chapters, but MKVMerge -I doesn't seem to mention the existence of multiple editions...

MKVMerge could provide a more detailed breakdown of the chapters that includes editions, but if you want to "see" each individual title as a separate file Mosu would have to either completely reinvent the -I option or create a secondary Info option to support it.

[ndjamena]

Would it be possible to include some indication of "Pre-parsing FLAC file: ##%" in the progress bar. I keep thinking it isn't working.

Yes.

Exactly. This is the "ordered chapters", which has been a feature in the mkv specs for many years as I understand it.

It's of course up to Mosu to decide how he wants to implement this, but I think:

1. it would be nice to see the separate editions clearly in the track list (with perhaps a flag or someting to show the track is virtual)
2. the above point 1 should also allow demuxers to demux (or extract as separate mkvs) the separate editions (to for example bring back the editions as separate mkvs if needed in the future)

As I understand, there are no sync issues because you are using eac3to to demux (eac3to fixes sync issues).

This means that when using mkvtoolnix to load the bluray playlist directly there will be sync issues?

This is what I get in the output with Makemkv on the Avatar extended cut:

This is up to 80% of the remux, more is in the log for the last 20%.

@ Mosu

This happens with all of the seamless branching blurays.

I have now also tested remuxing this by loading the playlist directly in mkvtoolnix: it shows absolutely no information regarding audio skew or dropped frames.

I understand this means mkvtoolnix has a sync issue when seamless branching happens?

Until this is fixed, shouldn't the output display a warning that the resulting mkv will have sync issues to at least let the user know?

Thanks.

All these ms add up to a lot.... which isn't fixed when remuxing with mkvtoolnix?

Neither mkvtoolnix nor gmkvextractgui sees the multiple editions contained in the mkv (they only see the first title).

In the Xin1Generator thread is a way discribed.

I never extract from mkv.
The editions are generated while loading a mkv in your player. When the player can interpret the chapters.xml(inside mkv)
then it shows and work.

BUT there are every ONE big video stream(audio and subs too).

No, eac3to will demux the streams only if you use the "BD-demux" button otherwise MKVToolNix-GUI(MTX-GUI) load all m2ts files in order and mux it directly from the BD-structure.

When you load a playlist directly in the MTX-GUI you will never get multi editions mkv's, also not if you all m2ts load manually. The "editions-magic" is a part of the chapters.xml AND the tags.xml.

I could do a bit more for Matroska, but the old song: no player or splitter supports this features.

Greetings Mosu.
Appreciate if you could kindly assist with a problem of wav audio (LPCM) in mkv not recognised by tsmuxer.
Many thanks and best regards.

How can I get MKVToolNix GUI to generate a chapter mark between appended files?

I think we can definitely see this feature going in there)?

You only see one video track because the editions are solely virtual constructs indicated by the chapters. Each edition in the chapter references different parts of that one video track. I don't have any plans on implementing support for working with editions the same way you work with tracks or something like that as that would take a huge effort and amount of time. Sorry.
