Using mkvbatchmultiplex¶
The application has a very simple interface:

mkvbatchmultiplex¶
Requirements¶
In order for mkvbatchmultiplex to work as intended there are certain conditions in the structure of the files in the source directories. This has to be this way because we are working with group of files not one files. And is a batch process there should not be any user input requested when working of a job.
Structure for directories:
The media files in the directory have to be of the same type. The program will read the directory taking information form the template so it will apply instruction to the same type of file.
The files have to be consistent that is the same number of tracks of the same type and order. Files found different from template will not be processed.
If more than one file are involved in the operation there have to be one of each for the resulting tracks. For example:
The instruction if for a video file and a subtitle file to be multiplexed and there are 13 video files then there have to be 13 subtitle files.
One source directory:
/source1
/Destination
video - S01E01.avi
video - S01E01.mkv
video - S01E01.srt
video - S01E02.avi
video - S01E02.mkv
video - S01E02.srt
…
…
video - S01E13.avi
video - S01E13.mkv
video - S01E13.srt
For attachments the same files will be use for every operation.
Files of the same type in the instruction have to be in different directories. To process the files names are not used to pair the sources the position is:
Source1 AVI container source2 lang1.srt source3 lan2.srt:
Two source directory:
/directory1
/directory2
/destination
video - S01E01.avi
video - S01E01.srt
video - S01E01.mkv
video - S01E02.avi
video - S01E02.srt
video - S01E02.mkv
…
…
…
video - S01E13.avi
video - S01E13.srt
video - S01E13.mkv
This the best option for the working directories.
Functionality¶
Source File Naming¶
The source and destination directories are taken from the template. The resulting name in the directory is taken from the first media file selected for the multiplexing. The name for the subsequent files is not used what is use is the order read. The program will pair the files by order found in the directory:
/directory1
/directory2
/destination
video - S01E01.avi
sub01.srt
video - S01E01.mkv
video - S01E02.avi
sub02.srt
video - S01E02.mkv
…
…
…
video - S01E13.avi
sub03.srt
video - S01E13.mkv
If the destination directory already have a file with the destination name a prefix new- will be used. The job operation is not destructive no file will be overwritten.
Settings¶
The only setting is to enable logging. The log will be saved one ~/.mkvbatchmultiplex/mkvBatchMultiplex.log with a rotation of 10 log files.

Enable logging.¶
Buttons¶

Paste Clipboard
Paste command line from system Clipboard is expected to be from a copy to clipboard from MKVToolnix.
Process
Start working on the command line. The output of the job can be subsequent on the Job Output tab.
Add Job
If there is more than one operation to be done Add Job will add the command to a job queue
Process Jobs
Start working on the job queue. While the jobs are running more jobs can be added to the queue.
Clear Output
Clear the output of the main window
Clear/Reset
Clear contents of all output windows and the job table.
The following buttons are for troubleshooting
Analysis
Shows some information on the parse of the command line this can help solving problems as to why the command is not been accepted
Source Files
Shows the source files to be worked with.
Commands
Show commands to be executed as lists to be submitted to a subprocess
Check Files
Verify the files to be worked on and signals any command that don’t pass consistency test. Flagged commands will not be processed.
Tabs¶
Job(s)
Displays a table with jobs added for current session. Jobs Status column:
Waiting are in queue for processing. While the job is waiting with right click it can be changed to Skip
Running is the current running job.
Done job already processed.
Skip job will not be processed. While in Skip status the job can be changed to Waiting if the working thread is running it will be processed automatically. If not it can be started with Process Jobs buttons
Job(s) Output
Displays output messages generated by the running jobs.

The file 'C:\tests\NewFiles\new-video'S01E05 (15).mkv' has been opened for writing. Progress: 100% The cue entries (the index) are being written... Multiplexing took 0 seconds.
Job(s) Error(s)
Display any errors found generally this means any files with inconsistent with original files track order or type don’t match.
Error: In structure File Nme: C:\tests\VideoFiles\video - S01E04.avi File Format: -AVI- Track: 1 Order: 0 - Video Codec: None Language: None Format: MPEG-4 Visual File Nme: C:\tests\VideoFiles\video-S01E01.avi File Format: -AVI- Track: 1 Order: 0 - Video Codec: None Language: None Format: MPEG-4 Visual Track: 2 Order: 1 - Audio Codec: None Language: None Format: MPEG Audio
Rename Files
For the majority of media servers a good naming scheme for the episodes of a series is:
Series Name - S01E01.mkv
The part S01E01 represents season 1 episode 1. If the files been process don’t follow this scheme the system provides the ability to rename the output files. Using regular expressions you can rename the output file names. Also if regular expressions are to difficult a new name with and index in the form:
Series Name - S01E<i: NN>
<i: NN> where NN is a number can be 0 padded. It will be substituted by a number starting with the value NN.
Rename with incremental index.¶
As shown in the figure to rename using and index set the regex to * (asterisk, and invalid regex to use). Then enter the new name with the increment mark in the desired position. Once satisfied push button Apply Rename
Examples:
Rename with incremental index.¶
In this example we see that the rename result would be wrong. The order of the original files is not sorted.
Rename with regex.¶
For regular expressions the order is not important the episode number is taken from the name. Also missing episodes won’t affect the rename of the files.
The operation can be undone with the Undo pushbutton before starting the execution of the batch operation.
