NAME

mkvmerge - Merge multimedia streams into a Matroska file

SYNOPSIS

mkvmerge[global options] -o out [

options1] <file1> [[options2] <file2> ...] [@optionsfile]

DESCRIPTION

This program takes the input from several media files and joinstheir streams (all of them or just a selection) into a Matroska file.<http://www.matroska.org/>

Global options:

--title <title>: Sets the general title for the output file, e.g. the movie name.
--global-tags <file>: Read global tags from the XML file. See the section about tagsbelow for details.
--command-line-charset <charset>: Sets the charset to convert strings given on the command line from. It defaultsto the charset given by system's current locale. This settings applies toarguments of the following options: --title, --track-name and--attachment-description.

Chapter handling: (global options)

--chapter-charset <charset>: Sets the charset that is used for the conversion to UTF-8 for simple chapterfiles. Defaults to the current system locale. See the section about chaptersbelow for details.
--cue-chapter-name-format <format>: mkvmerge supports reading CUE sheets for audio files as the input forchapters. CUE sheets usually contain the entries PERFORMER andTITLE for each index entry. mkvmerge uses these two stringsin order to construct the chapter name. With this option the format usedfor this name can be set. The following meta characters are supported:
%p is replaced by the current entry's PERFORMER string,
%t is replaced by the current entry's TITLE string,
%n is replaced by the current track number and
%N is replaced by the current track number padded with a leading zero ifit is < 10.
Everything else is copied as-is.
If this option is not given then mkvmerge defaults to theformat '%p - %t' (the performer, followed by a space, a dash,another space and the title).
--chapters <file>: Read chapter information from the file. See the section about chaptersbelow for details.

General output control (advanced global options):

--no-cues: Tells mkvmerge not to create and write the cue data which can be comparedto an index in an AVI. Matroska files can be played back without the cuedata, but seeking will probably be imprecise and slower. Use this only ifyou're really desperate for space or for testing purposes. See also option--cues which can be specified for each input file.
--no-clusters-in-meta-seek: Tells mkvmerge not to create a meta seek element at the end of the filecontaining all clusters. See also the section about MATROSKA FILE LAYOUT.
--disable-lacing: Disables lacing for all tracks. This will increase the file's size, especiallyif there are many audio tracks. This option is not intended for everyday use.
--enable-durations: Write durations for all blocks. This will increase file size and does notoffer any additional value for players at the moment.
--enable-timeslices: Write time slices for all blocks with more than one frame (lacedblocks). This will increase file size and does not offer anyadditional value for players at the moment.

File splitting and linking (more global options):

--split-max-files <n>: Create at most n files, even if the last file will be longer or largerthan indicated by --split.
--link: Link files to one another when splitting the output file. See thesection FILE LINKING below for details.
--link-to-previous <UID>: Links the first output file to the segment with the given UID. See thesection FILE LINKING below for details.
--link-to-next <UID>: Links the last output file to the segment with the given UID. See thesection FILE LINKING below for details.

Attachment support (more global options):

-a, --atracks <n,m,...>: Copy the audio tracks n, m etc. The numbers are track IDs whichcan be obtained with the --identify switch. They're not simplythe track numbers (see section TRACK IDS). Default: copy all audiotracks.
-d, --vtracks <n,m,...>: Copy the video tracks n, m etc. The numbers are track IDs whichcan be obtained with the --identify switch (seesection TRACK IDS). They're not simplythe track numbers. Default: copy all video tracks.
-s, --stracks <n,m,...>: Copy the subtitle tracks n, m etc. The numbers are track IDs whichcan be obtained with the --identify switch (seesection TRACK IDS). They're not simplythe track numbers. Default: copy all subtitle tracks.
-A, --noaudio: Don't copy any audio track from this file.
-D, --novideo: Don't copy any video track from this file.
-S, --nosubs: Don't copy any subtitle track from this file.
--no-chapters: If the source is a Matroska file then don't copy chapters from it.
--no-attachments: If the source is a Matroska file then don't copy attachments from it.
--no-tags: If the source is a Matroska file then don't copy tags from it.
-y, --sync <TID:d[,o[/p]]>: Synchronize manually, delay the audio track with the id TID by dms. The track IDs are the same as the ones given with --identify (seesection TRACK IDS).
d > 0: Pad with silent samples.
d < 0: Remove samples from the beginning.
o/p: adjust the timestamps by o/p to fixlinear drifts. p defaults to 1000 if omitted. Both o andp can be floating point numbers.
Defaults: no manual sync correction (which is the same as d = 0 ando/p = 1.0).
This option can be used multiple times for an input file applying to severaltracks by selecting different track IDs each time.
--cues <TID:none|iframes|all>: Controls for which tracks cue (index) entries are created for the given track(see section TRACK IDS). none inhibits the creation of cue entries.For iframes only blocks with no backward or forwardreferences ( = I frames in video tracks) are put into the cue sheet. allcauses mkvmerge to create cue entries for all blocks which will makethe file very big.
The default is iframes for video tracks and none for all others.See also option --no-cues which inhibits the creation of cueentries regardless of the --cues options used.
This option can be used multiple times for an input file applying to severaltracks by selecting different track IDs each time.
--default-track <TID>: Sets the 'default' flag for the given track (see section TRACK IDS).If the user does not explicitly select a track himself then the player shouldprefer the track that has his 'default' flag set. Only one track of each kind(audio, video, subtitles) can have his 'default' flag set.
This option can be used multiple times for an input file applying to severaltracks by selecting different track IDs each time.
--track-name <TID:name>: Sets the track name for the given track (see section TRACK IDS) toname.
--language <TID:language>: Sets the language for the given track (see section TRACK IDS). OnlyISO639-2 codes are allowed. All languages including their ISO639-2 codes can belisted with the --list-languages option.
This option can be used multiple times for an input file applying to severaltracks by selecting different track IDs each time.
-t, --tags <TID:file>: Read tags for the track with the number TID from the file. Seethe section about tags below for details.
--aac-is-sbr <TID>: Tells mkvmerge that the track with the ID TID is SBR AAC (alsoknown as HE-AAC or AAC+). This options is needed if a) the source file is anAAC file (NOT for a Matroska file) and b) the AAC file contains SBR AAC data.The reason for this switch is that it is technically impossible toautomatically tell normal AAC data from SBR AAC data without decoding acomplete AAC frame. As there are several patent issues with AAC decoders Iwon't implement this decoding stage. So for SBR AAC files this switch ismandatory. The resulting file might not play back correctly or even not atall if the switch was omitted.
If the source file is a Matroska file then the CodecID should be enough todetect SBR AAC. However, if the CodecID is wrong then this switch can be usedto correct that.
--timecodes <TID:filename>: Read the timecodes to be used for the specific track ID from filename.These timecodes forcefully override the timecodes that mkvmergenormally calculates. Read the section about EXTERNAL TIMECODE FILES.
--track-order <TID1[,TID2,...]>: This option changes the order in which the tracks for an input file arecreated. If some track IDs are omitted then those tracks are created after theones given with this option have been created.

Options that only apply to video tracks:

--display-dimensions <TID:widthxheight>: Matroska files contain two values that set the display properties that aplayer should scale the image on playback to: display width and display height.These values can be set with this option, e.g. '1:640x480'.
Another way to specify the values is to use the--aspect-ratio option (see below). These options are mutuallyexclusive.
--aspect-ratio <TID:ar|w/h>: Matroska files contain two values that set the display properties thata player should scale the image on playback to: display width anddisplay height. With this option mkvmerge will automaticallycalculate the display width and display height based on the image'soriginal width and height and the aspect ratio given with this option.The ratio can be given either as a floating point number or as'width/height', e.g. 16/9.
Another way to specify the values is to use the--aspect-ratio option (see above). These options are mutuallyexclusive.

Options that only apply to text subtitle tracks:

--compression <TID:method>: Selects the compression method to be used for the VobSub track. Note that theplayer also has to support this method! Valid values are 'none' and 'zlib'.The default is 'zlib' compression.

Other options:

could be converted into the following option file:
# Write to the file 'my file.mkv'.
-o
my file.mkv
# Only take the video from 'a movie.avi'.
-A
a movie.avi
sound.ogg

USAGE

For each file the user can select which tracks mkvmerge should take.They are all put into the file specified with '-o'. A list of known(and supported) source formats can be obtained with the '-l' option.

EXAMPLES

Let's assume you have a file called MyMovie.avi and the audio track in aseparate file, e.g. MyMovie.wav. First you want to encode the audio toOGG:

$ oggenc -q4 -oMyMovie.ogg MyMovie.wav

After a couple of minutes you can join video and audio:

$ mkvmerge -o MyMovie-with-sound.mkv MyMovie.avi MyMovie.ogg

If your AVI already contains an audio track then it will be copied as well(if mkvmerge supports the audio format). To avoid that simply do

$ mkvmerge -o MyMovie-with-sound.mkv -A MyMovie.avi MyMovie.ogg

After some minutes of consideration you rip another audio track, e.g.the director's comments or another language to MyMovie-add-audio.wav.Encode it again and join it up with the other file:

$ oggenc -q4 -oMyMovie-add-audio.ogg MyMovie-add-audio.wav
$ mkvmerge -o MM-complete.mkv MyMovie-with-sound.mkv MyMovie-add-audio.ogg

The same result can be achieved with

$ mkvmerge -o MM-complete.mkv -A MyMovie.avi MyMovie.ogg
MyMovie-add-audio.ogg

Now fire up mplayer and enjoy. If you have multiple audio tracks (or evenvideo tracks) then you can tell mplayer which track to play with the'-vid' and '-aid' parameters. These are 0-based and do notdistinguish between video and audio.

If you need an audio track synchronized you can do that easily. First findout which track ID the Vorbis track has with

$ mkvmerge --identify outofsync.ogg

Now you can use that ID in the following command line:

$ mkvmerge -o goodsync.mkv -A source.avi -y 12345:200 outofsync.ogg

This would add 200ms of silence at the beginning of the audio track with theID 12345 taken from outofsync.ogg.

Some movies start synced correctly but slowly drift out of sync. For thesekind of movies you can specify a delay factor that is applied to alltimestamps - no data is added or removed. So if you make that factor toobig or too small you'll get bad results. An example is that an episodeI transcoded was 0.2 seconds out of sync at the end of the movie whichwas 77340 frames long. At 29.97fps 0.2 seconds correspond to approx. 6frames. So I did

$ mkvmerge -o goodsync.mkv -y 23456:0,77346/77340 outofsync.mkv

The result was fine.

The sync options can also be used for subtitles in the same manner.

For text subtitles you can either use some Windows software (likeSubRipper) or the subrip package found in transcode(1)'ssources (in contrib/subrip). The general process is:

$ mkvmerge -o with-lang-codes.mkv --language 2:ger --language 3:dutwithout-lang-codes.mkv

As you can see you can use the --language switch multiple times.

Maybe you'd also like to have the player use the Dutch language as the defaultlanguage. You also have extra subtitles, e.g. in English and French, and wantto have the player display the French ones by default. This can be done with

$ mkvmerge -o with-lang-codes.mkv --language 2:ger --language 3:dut--default-track 3 without-lang-codes.mkv --language 0:eng english.srt--default-track 0 --language 0:fre french.srt

If you do not see the language or default track flags that you've specifiedin mkvinfo's output then please read the section about DEFAULTVALUES.

TRACK IDS

Some of the options for mkvmerge need a track ID to specify which trackthey should be applied to. Those track IDs are printed by the readers whendemuxing the current input file, or if mkvmerge is called with the--identify option. Track IDs are assigned like this:

*: Ogg/OGM files: The track's ID is its serial number as given in the Ogg streamheader page.
*: Matroska files: The track's ID is the track number as reported by mkvinfoor mkvmerge --identify. It is not the track UID.

The special track ID '-1' is a wild card and applies the given switch to alltracks that are read from an input file. This was the behaviour of theseswitches prior to version 0.4.4.

The options that use the track IDs are: --atracks, --vtracks,--stracks, --sync, --default-track, --cuesand --language.

SUBTITLES

There are several text subtitle formats that can be embedded into Matroska.At the moment mkvmerge supports only text subtitle formats.These subtitles must be recoded to UTF-8 so that they can be displayedcorrectly by a player.

mkvmerge does this conversion automatically based on the system's currentlocale. If the subtitle charset is not the same asthe system's current charset then the user can use --sub-charsetswitch. If the subtitles are already encoded in UTF-8 then you can use--sub-charset UTF-8.

The following subtitle formats are supported at the moment:

Each segment is identified by a unique 128 bit wide segment UID. This UIDis automatically generated by mkvmerge. The linking is done primarilyvia putting the segment UIDs of the previous/next file into the segmentheader information. mkvinfo(1) prints these UIDs if it finds them.

If a file is split into several smaller ones and linking is used then thetimecodes will not start at 0 again but will continue where the last filehas left off. This way the absolute time is kept even if the previous filesare not available (e.g. when streaming). If no linking is used then thetimecodes should start at 0 for each file. By default mkvmerge does notuse file linking. If you want that you can turn it on with the'-link' option. This option is only useful if splittingis activated as well.

Regardless of whether splitting is active or not the user can tellmkvmerge to link the produced files to specific UIDs. This is achievedwith the options '--link-to-previous' and '--link-to-next'.These options accept a segment UID in the format that mkvinfo(1)outputs: 16 hexadecimal numbers between 0x00 and 0xff prefixed with '0x' each,e.g. 0x41 0xda 0x73 0x66 0xd9 0xcf 0xb2 0x1e 0xae 0x78 0xeb 0xb4 0x5e 0xca0xb3 0x93. Alternatively a shorter form can be used: 16 hexadecimal numbersbetween 0x00 and 0xff without the '0x' prefixes and without the spaces, e.g.41da7366d9cfb21eae78ebb45ecab393.

If splitting is used then the first file is linked to the UID given with'--link-to-previous' and the last file is linked to the UID givenwith '--link-to-next'. If splitting is not used then the oneoutput file will be linked to both of the two UIDs.

DEFAULT VALUES

The Matroska specs say that some elements have a default value. Usually anelement is not written to the file if its value is equal to its defaultvalue in order to save space. The elements that the user might miss inmkvinfo's output are the language and the default track flag.The default value for the language is English (eng),and the default value for the default track flag is true. Thereforeif you used --language 0:eng for a track then it will not show upin mkvinfo's output.

ATTACHMENTS

Maybe you also want to keep some photos along with your Matroska file, oryou're using SSA subtitles and need a special TrueType font that's reallyrare. In these cases you can attach those files to the Matroska file. Theywill not be just appended to the file but embedded in it. A player can thenshow those files (the 'photos' case) or use them to render the subtitles(the 'TrueType fonts' case).

Here's an example how to attach a photo and a TrueType font to the outputfile:
$ mkvmerge -o output.mkv -A video.avi sound.ogg --attachment-description'Me and the band behind the stage in a small get-together'--attachment-mime-type image/jpeg --attach-file me_and_the_band.jpg--attachment-description 'The real rare and unbelievably good looking font'--attachment-type application/octet-stream--attach-file really_cool_font.ttf

CHAPTERS

The Matroska chapter system is more powerful than the old known system usedby OGMs. The full specs can be found at<http://cvs.corecodec.org/cgi-bin/viewcvs.cgi/*checkout*/matroska/doc/website/technical/specs/chapters/index.html>

mkvmerge supports two kinds of chapter files as its input. The firstformat, called 'simple chapter format', is the same format that the OGM toolsexpect. The second format is a XML based chapter format which supports allof Matroska's chapter functionality.

The simple chapter format

It looks basically like this:

CHAPTER01=00:00:00.000
CHAPTER01NAME=Intro
CHAPTER02=00:02:30.000
CHAPTER02NAME=Baby prepares to rock
CHAPTER03=00:02:42.300
CHAPTER03NAME=Baby rocks the house

mkvmerge will transform every pair or lines (CHAPTERxx and CHAPTERxxNAME)into one Matroska ChapterAtom. It does not set anyChapterTrackNumber which means that the chapters all apply to alltracks in the file.

The charset used in the file is assumed to be the same charset that thecurrent system's locale returns. If this is not the case then the swith--chapter-charset should be used. If the file contains a validBOM (byte order marker) then all UTF styles are converted automatically.In this case --chapter-charset is simply ignored. You can usemkvinfo or mkvextract to verify that the chapter names havebeen converted properly.

The XML based chapter format

The XML based chapter format looks like this:

<?xml version='1.0' encoding='ISO-8859-1'?>
<!DOCTYPE Chapters SYSTEM 'matroskachapters.dtd'>
<Chapters>
<EditionEntry>
<ChapterAtom>
<ChapterTimeStart>00:00:30.000</ChapterTimeStart>
<ChapterTimeEnd>00:01:20.000</ChapterTimeEnd>
<ChapterDisplay>
<ChapterString>A short chapter</ChapterString>
<ChapterLanguage>eng</ChapterLanguage>
</ChapterDisplay>
<ChapterAtom>
<ChapterTimeStart>00:00:46.000</ChapterTimeStart>
<ChapterTimeEnd>00:01:10.000</ChapterTimeEnd>
<ChapterDisplay>
<ChapterString>A part of that short chapter</ChapterString>
<ChapterLanguage>eng</ChapterLanguage>
</ChapterDisplay>
</ChapterAtom>
</ChapterAtom>
</EditionEntry>
</Chapters>

With this format three things are possible that are not possible with thesimple chapter format: 1) The timestamp for the end of the chapter can beset, 2) chapters can be nested, 3) the language and country can be set.

The mkvtoolnix distribution contains some sample files in the docsubdirectory which can be used as a basis.

General notes

When splitting files mkvmerge will correctly adjust the chapters aswell. This means that each file only includes the chapter entries thatapply to it, and that the timecodes will be offset to match the new timecodesof each output file.

mkvmerge is able to copy chapters from Matroska source files unless thisis explicitely disabled with the --no-chapters option. At themoment mkvmerge is limited to one 'buch of chapters' globally. This meansthat only the first chapter section found in all source files is used. Ifthe user specified chapters on the command line then these take precedenceover any chapters found in source files. mkvmerge does not mergechapters. This must be done manually by using mkvextract to extractthe chapter information and editing the resulting files.

One shortcoming is that mkvmerge cannot parse chapter information foundin OGM files.

MATROSKA FILE LAYOUT

The Matroska file layout is quite flexible. mkvmerge will render a filein a predefined way. The resulting file looks like this:

[EBML head] [segment {meta seek #1} {attachments} {chapters}[segment information] [track information] [cluster 1] {cluster 2} ...{cluster n} {cues} {meta seek #2} {tags}]

The elements in curly braces are optional and depend on the contents andoptions used. Some notes:

Timecode file format v1

This format starts with this line:
# timecode format v1
The second line gives the default number of frames per second:
assume 27.930
All following lines contain three numbers separated by commas: thestart frame (0 is the first frame), the end frame and the number offrames in this range. The FPS is a floating point number with the dotdefault FPS is used. Example:
800,1000,25
1500,1700,30

Timecode file format v2

In this format each line contains a timecode for the next frame. Thistimecode must be given in ms precision. It can be a floating point number,but it doesn't have to be. You must give at least as many timecodelines as there are frames in the track. Example for 25fps:
# timecode format v2
0
40
80
etc.

NOTES

What works:

*: Manual audio synchronization for PCM sound (who needs it anyway?)

The resulting file might not play back correctly or even not atall if the switch was omitted.
If the source file is a Matroska file then the CodecID should be enough todetect SBR AAC. However, if the CodecID is wrong then this switch can be usedto correct that.
--timecodes <TID:filename>: Read the timecodes to be used for the specific track ID from filename.These timecodes forcefully override the timecodes that mkvmergenormally calculates. Read the section about EXTERNAL TIMECODE FILES.
--track-order <TID1[,TID2,...]>: This option changes the order in which the tracks for an input file arecreated. If some track IDs are omitted then those tracks are created after theones given with this option have been created.

Options that only apply to video tracks:

--display-dimensions <TID:widthxheight>: Matroska files contain two values that set the display properties that aplayer should scale the image on playback to: display width and display height.These values can be set with this option, e.g. '1:640x480'.
Another way to specify the values is to use the--aspect-ratio option (see below). These options are mutuallyexclusive.
--aspect-ratio <TID:ar|w/h>: Matroska files contain two values that set the display properties thata player should scale the image on playback to: display width anddisplay height. With this option mkvmerge will automaticallycalculate the display width and display height based on the image'soriginal width and height and the aspect ratio given with this option.The ratio can be given either as a floating point number or as'width/height', e.g. 16/9.
Another way to specify the values is to use the--aspect-ratio option (see above). These options are mutuallyexclusive.

Options that only apply to text subtitle tracks:

--compression <TID:method>: Selects the compression method to be used for the VobSub track. Note that theplayer also has to support this method! Valid values are 'none' and 'zlib'.The default is 'zlib' compression.

Other options:

could be converted into the following option file:
# Write to the file 'my file.mkv'.
-o
my file.mkv
# Only take the video from 'a movie.avi'.
-A
a movie.avi
sound.ogg

USAGE

EXAMPLES

Let's assume you have a file called MyMovie.avi and the audio track in aseparate file, e.g. MyMovie.wav. First you want to encode the audio toOGG:

$ oggenc -q4 -oMyMovie.ogg MyMovie.wav

After a couple of minutes you can join video and audio:

$ mkvmerge -o MyMovie-with-sound.mkv MyMovie.avi MyMovie.ogg

If your AVI already contains an audio track then it will be copied as well(if mkvmerge supports the audio format). To avoid that simply do

$ mkvmerge -o MyMovie-with-sound.mkv -A MyMovie.avi MyMovie.ogg

After some minutes of consideration you rip another audio track, e.g.the director's comments or another language to MyMovie-add-audio.wav.Encode it again and join it up with the other file:

$ oggenc -q4 -oMyMovie-add-audio.ogg MyMovie-add-audio.wav
$ mkvmerge -o MM-complete.mkv MyMovie-with-sound.mkv MyMovie-add-audio.ogg

The same result can be achieved with

$ mkvmerge -o MM-complete.mkv -A MyMovie.avi MyMovie.ogg
MyMovie-add-audio.ogg

If you need an audio track synchronized you can do that easily. First findout which track ID the Vorbis track has with

$ mkvmerge --identify outofsync.ogg

Now you can use that ID in the following command line:

$ mkvmerge -o goodsync.mkv -A source.avi -y 12345:200 outofsync.ogg

This would add 200ms of silence at the beginning of the audio track with theID 12345 taken from outofsync.ogg.

$ mkvmerge -o goodsync.mkv -y 23456:0,77346/77340 outofsync.mkv

The result was fine.

The sync options can also be used for subtitles in the same manner.

For text subtitles you can either use some Windows software (likeSubRipper) or the subrip package found in transcode(1)'ssources (in contrib/subrip). The general process is:

$ mkvmerge -o with-lang-codes.mkv --language 2:ger --language 3:dutwithout-lang-codes.mkv

As you can see you can use the --language switch multiple times.

$ mkvmerge -o with-lang-codes.mkv --language 2:ger --language 3:dut--default-track 3 without-lang-codes.mkv --language 0:eng english.srt--default-track 0 --language 0:fre french.srt

If you do not see the language or default track flags that you've specifiedin mkvinfo's output then please read the section about DEFAULTVALUES.

TRACK IDS

*: Ogg/OGM files: The track's ID is its serial number as given in the Ogg streamheader page.
*: Matroska files: The track's ID is the track number as reported by mkvinfoor mkvmerge --identify. It is not the track UID.

The special track ID '-1' is a wild card and applies the given switch to alltracks that are read from an input file. This was the behaviour of theseswitches prior to version 0.4.4.

The options that use the track IDs are: --atracks, --vtracks,--stracks, --sync, --default-track, --cuesand --language.

SUBTITLES

The following subtitle formats are supported at the moment:

CHAPTERS

The simple chapter format

It looks basically like this:

CHAPTER01=00:00:00.000
CHAPTER01NAME=Intro
CHAPTER02=00:02:30.000
CHAPTER02NAME=Baby prepares to rock
CHAPTER03=00:02:42.300
CHAPTER03NAME=Baby rocks the house

The XML based chapter format

The XML based chapter format looks like this:

The mkvtoolnix distribution contains some sample files in the docsubdirectory which can be used as a basis.

General notes

One shortcoming is that mkvmerge cannot parse chapter information foundin OGM files.

MATROSKA FILE LAYOUT

The Matroska file layout is quite flexible. mkvmerge will render a filein a predefined way. The resulting file looks like this:

[EBML head] [segment {meta seek #1} {attachments} {chapters}[segment information] [track information] [cluster 1] {cluster 2} ...{cluster n} {cues} {meta seek #2} {tags}]

The elements in curly braces are optional and depend on the contents andoptions used. Some notes:

Timecode file format v1

Timecode file format v2

NOTES

What works:

*: Manual audio synchronization for PCM sound (who needs it anyway?)
