batch remux with Mkvmerge

[Chakabear13]

hello, I hope somebody can help me. Currently I have about 70 mkvs. 25 of them I remuxed already. that leaves me with the rest of the videos to remux.

this is the process I did
> open Mkvmerge> add .mkv file> uncheck current sub(s)> add edited .srt (name: ...track02)> change language of that srt to "english">highlight edited .srt and click "up" to move it above chapter track> add to queue or start muxing.

before this process. I removed all subs using Mkvextract then check & correct any errors.

I was reading here and found that you can use batch file to automate this process. Unfortunately I have no clue on how to make a batch file.

thank you

• open the mkv you want to remux in MKVToolnix and apply your settings (remove sub, add srt, set to English...)
  
  
• select muxing > Copy command line to clipboard
  
  
• create the file remux.bat in the folder where your mkvs reside
  
  
• paste the contents of the clipboard into the file
  
  
• add the blue text "if exist..." before and the closing ) after that text
  
  
• change the path of mkvmerge to where you've installed it
  
  
• the -S will remove subs already present in the mkv
  
  
• change all paths to the placeholders marked red:
  
  
  • "m:\remux\%%a" <- the remuxed files will be written to m:\remux
    
    
  • "%%a" <- this means all mkvs in the input folder where the remux.bat is started from
    
    
  • "%%~na.srt" <- the srt you want to add (should be in the folder with the mkvs having the same name)
  
  
• open a command window in the source dir
  
  
• type remux [ENTER]
  

if exist *.mkv mkdir m:\remux
for %%a in (*.mkv) do ("D:\Programme\MKVtoolnix\mkvmerge.exe" -S -o "m:\remux\%%a" "--language" "0:eng" "--default-track" "0:no" "--forced-track" "0:no" "--display-dimensions" "0:1280x720" "--language" "1:eng" "--default-track" "1:yes" "--forced-track" "1:no" "-a" "1" "-d" "0" "-S" "-T" "--no-global-tags" "--no-chapters" "(" "%%a" ")" "--language" "0:eng" "--default-track" "0:no" "--forced-track" "0:no" "-s" "0" "-D" "-A" "-T" "--no-global-tags" "--no-chapters" "(" "%%~na.srt" ")" "--track-order" "0:0,0:1,1:0" "--title" "" "--engage" "no_cue_duration" "--engage" "no_cue_relative_position" "--disable-track-statistics-tags"
)

If you pasted everything right, you'll see mkvmerge start. If not, you can read the error message.

[Chakabear13]

I think I lost you in the last steps.

This is the result after following your instructions.

if exist *.mkv mkdir m:\remux for %%a in (*.mkv) do ("C:\Program Files (x86)\MKVToolNix\mkvmerge.exe" -S -o "m:\remux\%%a" "--language" "0:eng" "--default-track" "0:yes" "--forced-track" "0:no" "--display-dimensions" "0:984x720" "--language" "1:eng" "--default-track" "1:yes" "--forced-track" "1:no" "-a" "1" "-d" "0" "-S" "-T" "--no-global-tags" "(" "%%a" ")" "--language" "0:eng" "--forced-track" "0:no" "-s" "0" "-D" "-A" "-T" "--no-global-tags" "--no-chapters" "(" "%%~na.srt" ")" "--track-order" "0:0,0:1,1:0" )


Below is the original lines that I copied from mkvmerge.

"C:\Program Files (x86)\MKVToolNix\mkvmerge.exe" -o "C:\\Users\\Mark\\Desktop\\Movies\\The Mummy (1932) 720p\\The Mummy (1932) 720p (1).mkv" "--language" "0:eng" "--default-track" "0:yes" "--forced-track" "0:no" "--display-dimensions" "0:984x720" "--language" "1:eng" "--default-track" "1:yes" "--forced-track" "1:no" "-a" "1" "-d" "0" "-S" "-T" "--no-global-tags" "(" "C:\\Users\\Mark\\Desktop\\Movies\\The Mummy (1932) 720p\\The Mummy (1932) 720p.mkv" ")" "--language" "0:eng" "--forced-track" "0:no" "-s" "0" "-D" "-A" "-T" "--no-global-tags" "--no-chapters" "(" "C:\\Users\\Mark\\Desktop\\Movies\\The Mummy (1932) 720p\\The Mummy (1932) 720p_Track02.srt" ")" "--track-order" "0:0,0:1,1:0"


Questions:
1.
You said
"%%~na.srt" <- the srt you want to add (should be in the folder with the mkvs having the same name)

My subs don't have the same name with the movies but they are on the same location. However, all of them have "track02" at the end (ex.The Mummy (1932) 720p_Track02). Is there any way to do it with that name?

2.
"open a command window in the source dir" > Im not really sure how to do this. Im using windows 8. are you referring to command prompt?


3.
You also mention that "the remuxed files will be written to "\m:remux" > will this be the same as the directory of the orginal .mkv file?


Please excuse my ignorance. I'm totally noob with regards to codes & technical terms. I appreciate you helping me.

[Chetwood]

1. Should look like this

The Mummy (1932) 720p.mkv
The Mummy (1932) 720p.srt

If it's

The Mummy (1932) 720p.mkv
The Mummy (1932) 720p_Track02.srt

the batch entry would have to read

"%%~na_Track02.srt"

The base name has to be identical, otherwise the batch wouldn't mux the corresponding srt to the right mkv.

2.
Yes. It's called command prompt here or something.

3.
Nope, otherwise you would overwrite the old file and the batch would abort cause it does not add the (1) to the file name. Simply have all mkvs and srts in one dir and use any other dir as the target directory, in my case m:\remux (which usually is on another hdd so the process is faster).

Also, make sure the for %%a starts on a new line in the batch.

[Chakabear13]

Still having trouble. I cant figured out how to do this "open a command window in the source dir". The only way I know to open cmd is to go to start>run>type "CMD">enter. So, I just double-click on the batch file that I made. command prompt opens but not mkvmerge & here is the error message in cmd.

Just wanna clarify some things.

if exist *.mkv mkdir m:\remux for %%a in (*.mkv) do
> the "m:\remux" is the path where my mkv's and srt's?

1.Lets say I have my movies on Drive I>TEST>Movies then I should enter "I:\TEST\Movies" ?


&


"m:\remux\%%a" <- the remuxed files will be written to m:\remux

2. Is this my target folder?
I put "I:\remuxed movies\%%a" ?



I'm I missing something?

if exist *.mkv mkdir I:\TEST\Movies
for %%a in (*.mkv) do ("C:\Program Files (x86)\MKVToolNix\mkvmerge.exe" -S -o "I:\Remuxed movies\%%a" "--language" "0:eng" "--default-track" "0:no" "--forced-track" "0:no" "--display-dimensions" "0:1280x720" "--language" "1:eng" "--default-track" "1:yes" "--forced-track" "1:no" "-a" "1" "-d" "0" "-S" "-T" "--no-global-tags" "--no-chapters" "(" "%%a" ")" "--language" "0:eng" "--default-track" "0:no" "--forced-track" "0:no" "-s" "0" "-D" "-A" "-T" "--no-global-tags" "--no-chapters" "(" "%%~na_Track02.srt" ")" "--track-order" "0:0,0:1,1:0" "--title" "" "--engage" "no_cue_duration" "--engage" "no_cue_relative_position" "--disable-track-statistics-tags"

***EDIT***
I tried manually using mkvmerge without .bat to remux the file & I got the same result. The problem is there was no muxed mkv when I used the batch. Below is the output in mkvmerge.

Looks like an error in your movie, you'll likely have to go back and re-encode it.

[Chakabear13]

Finally GOT it! I was looking at the wrong folder.
A few hiccups though.

1. After remuxed "Chapter" tracks are gone. How can I keep the chapter track and only remove current subtitle(s)?

2. New subtitle file is not labeled "Default or Yes" in Default Track Flag.


3. Is there any way to tell if there is really an error muxing the files with this process?
I'm not very familiar looking at cmd so if I remuxed 50+ mkvs I wont be able to tell easily w/c one has error that needs to be fixed. (When I remuxed my first 25 mkvs. I got errors on some of them in mkvmerge).

4. If my mkv file has foreign audio will this batch change it to english?

Probably because you used I:\TEST\Movies and I:\Remuxed movies\. The first line of the batch creates the target directory. It only does it so Mkvmerge does not abort when the dir is not present. Thus, it must be the same dir.

The idea is to use ALL settings you need on a demo file in MKVToolnix: set subtitle to default yes if you want to play it back automatically, label the foreign audio to French or whatever. Only then copy the command-line to the clipboard and paste it into the batch where all you need to do is to replace the three instances where actual filenames are used.

Since we're talking batches here, the composition of the files needs to be identical! You cannot have one mkv where the subtitle is set to default yes and another where the subtitle is set to default no. Dunno why mmg copied this over but if you browse the command carefully, you'll notice "--no-chapters". Remove this and the chapters are muxed too.

That worked! thanks again. This will save me a lot of time.

My short suggestion:

:: lets go
@ECHO OFF &SETLOCAL disableDelayedExpansion
md output 2>nul
for %%a in (*.mkv) do mkvmerge -o "output\%%~a" -S "%%~a" --language eng "%%~na.track02.srt"

https://www.bunkus.org/videotools/mk.../mkvmerge.html

[Chetwood]

Right, known resource but since he mentioned subs I thought it'd be better to offer setting defaults and stuff as well.

[sneaker_ger]

@fryk
You forgot to supply a TrackID for the --language parameter:

for %%a in (*.mkv) do mkvmerge -o "output\%%~a" -S "%%~a" --language 0:eng "%%~na.track02.srt"

[Thunderbolt8]

can I create a batch file as well when I want to mux video + audio + subs for a TV series so that I wont have to do all the clicking for all the episodes of a season separately? does anyone know how I could do that?

the file names are all similar in such a case, only difference would be the S0XE0X season/episode part of the name.

[sneaker_ger]

"similar" is not a sufficient description. Post the exact names of a few files as an example others can work with.

[Thunderbolt8]

actually it is.

example: blablaS01E01.mkv blablaS01E01.dtsma blablaS01E01.ass blablaS01E02.mkv blablaS01E02.dtsma blablaS01E02.ass...

[sneaker_ger]

for %%a in (*.mkv) do mkvmerge -o "output\%%a" "%%a" "%%~na.dtsma" "%%~na.ass"

[Thunderbolt8]

where do I need to make the change if each output file should have a slightly different name if I choose to output in the same directory?

e.g. instead of blablaS01E01.mkv/.dtsma/.ass all output names should be named "outputblablaS01E01.mkv" so I wont override my input video file.

edit: its got to be

for %%a in (*.mkv) do mkvmerge -o "output%%a" "%%a" "%%~na.dtsma" "%%~na.ass"

then, right?

[sneaker_ger]

Yes, that's it.

You are completely right, thank you so much!

Wer lesen kann, ist echt im Vorteil

--language TID:language

Sets the language for the given track (see section track IDs). Both ISO639-2 language codes and ISO639-1 country codes are allowed. The country codes will be converted to language codes automatically. All languages including their ISO639-2 codes can be listed with the --list-languages option.

This option can be used multiple times for an input file applying to several tracks by selecting different track IDs each time.
