If I have a 3hr file and want to cut some part of it to have a 2hr one, AFAIK, I have to:
- open original_file.mkv
- cut with timecodes, for example I want to keep the parts 00:00:00.000-01:00:00.000,02:00:00.000-03:00:00.000
- then I have two 1hr files, original_file-001.mkv and original_file-002.mkv
- open the first one in the GUI, and append the second one, then mux and I'll have the 2hr original_file-001.mkv+original_file-002.mkv=target_file.mkv

Is there a way to skip the intermediate part1 and part2 files, and mux directly from original_file.mkv to target_file.mkv?
The app would read and mux the first hour, stop muxing and keep reading until the second hour, then restart to mux, in order to have only one final target file?
I know this is a feature request, AFAIK MKVToolnix GUI doesn't allow to do so, would it be possible to add this option in the future?

Thanks in advance!

Yes there is a way, insert a "+" in front of the second timestamp pair.

Code:
00:00:00.000-01:00:00.000,+02:00:00.000-03:00:00.000

Use "00:00:00.000-01:00:00.000,+02:00:00.000-03:00:00.000". (That's by the way included in both the ballon help in the GUI as well as in the documentation. Where did you get the idea that it isn't possible from?)

@Mosu

on windows 7 pro 32bit the mkvtoolnix-32-bit-28.2.0-revision-006 and revision-008 "mkvtoolnix-gui.exe" crash on startup




revision-005 works fine

I know. Inspired by your post I made a bug report on GitLab (that's the proper place for MKVToolNix bug reports) and mosu fixed it quickly.

Hello.

madshi has been working for some time now to improve HDR tone mapping in madVR. The relevant thread can be found on AVS forums. As of now, madVR is able to parse HDR files in order to measure nits content of files (thus producing an HDR measurement file). Me and others encountered problems with remuxes done with MKVToolNix, where the same remuxes done with MakeMKV were fine (MKVToolNix remuxes yielded incomplete HDR measurement files with seamless branched movies). madshi reported that the problematic remuxes done with MKVToolNix had weird timestamp.

At this point I'm switching to MakeMKV for all my future remuxes and will redo problematic remuxes (hopefully only seamless branched titles). I just wanted to make some people here aware of the "problem", maybe someone could investigate it further and fix whatever needs to be fixed (not saying something's wrong with MKVToolNix per se).

I'm willing to provide more information if someone requests it.

In a non related topic, my experience with MKVToolNix is that the tool is way slower than MakeMKV for the same task. MakeMKV is 2-3x faster for remuxing purpose. Does anyone noticed this?

Thanks.

zaemon

MKVToolNIX(MTX) has indeed a small issue while muxing seamless branching discs.
https://gitlab.com/mbunkus/mkvtoolnix/issues/2051
A workaround is to process the audio streams with eac3to.
MTX is able to preserve multi edition seamless branching discs with the help of chapterEditor, Makemkv can't do this.

@zaemon:
1. mkvmerge compresses the subtitles with zlib (to save some space), MakeMKV doesn't. This might make a bit of difference, but I don't think it could explain what you experienced.
2. What version of mkvmerge were you using to remux the files? Version 18.0 greatly improved the speed of remuxing H.264 and H.265 from unframed sources (everything except mp4 and mkv). And version 25.0 was the first (release) version that had a bug affecting seamless branching Blurays fixed. I will test if newer versions of mkvmerge are still slower.
3. There might of course still be a bug in mkvmerge. And for this the right place is actually on GitLab, not here in this thread. If you still have this bug with a recent version of mkvmerge (Here are the latest continuous builds of MKVToolNix. The very latest of it contains a new option should the GUI look bad because of High DPI stuff. (High DPI awareness has been enabled since version 28.0 and some users reported problems -- this does of course not affect the cli tools in any way.)) What you can do then: You can upload the output of mkvinfo -v -v -r <output.log> <Input.mkv>, where <Input.mkv> is once the file created by a recent version of mkvmerge and once the file created by MakeMKV. Upload it somewhere (normally, I'd say that you should upload it to the server of the MKVToolNix author, but I want to look at it myself, so please upload it to somewhere where I can get it (you may of course also upload it to his ftp-server, too)). And if you want mosu to be able to take a look at it, you should upload the whole, unencrypted disc to his ftp-server.

PS: It would have been nice if you had directly linked to the avsforum thread. Although I have to say that it really doesn't contain more relevant information than "Madshi said the timestamps are weird".

Thanks to both of you. First I'll try the eac3to method. I think it will be useful to know out of the three methods which one works. Now again, I had no problem with MKVToolNix prior to doing measurement with madVR: no warning, no error, no playback issue. I wouldn't consider it a bug at this point. But it's a fact that MKVToolNix's seamless branched remuxes are not compatible with the current dev version of madVR regarding HDR measurement files.

As for speeds, this does not really concern me but I was just curious to know why there was so much difference with MakeMKV.
