MKVToolnix is a set of tools for editing, manipulating, splitting, merging, extracting and inspecting Matroska (MKV) video files. It supports audio tracks in all common formats (AAC, FLAC, MP2, MP3 (E)AC3) as well as most subtitle formats like SRT/PGS/SUP VobSub and SSA.

MKVToolnix currently includes a Qt(TM)-based GUI for mkvmerge(1), with plans to also support mkvinfo, propedit and extract as additional functions.

MKV Merge

MKVmerge joins multiple files into one large one. It supports various merge modes, including Direct Stream Clone mode and Encoded stream mode – intended for use with Matroska(tm) files that contain several encoded streams – while offering the option to preserve or delete Cue data for specific tracks.

This program serves as a GUI frontend to the MKVToolNix utility called “mkvmerge(1)”, offering a simple yet powerful interface allowing you to select which tracks should be part of your final file and how they should be joined together. Queuing or immediate execution options allow users to operate it.

When using the –debug flag, mkvmerge(1) attempts to provide debugging information regarding its operation. This information comes in a series of specially formatted lines which can be understood by a GUI; starting with “#GUI#message”, followed by key/value pairs with names in the form ‘key1=value2’.

Normal operation of mkvmerge(1) will produce tags with statistics about each track, such as BPS, DURATION and NUMBER_OF_BYTES. By activating this option mkvmerge will stop writing these tags as well as overwriting existing ones with similar names.

If the –aspect-ratio option is enabled, mkvmerge(1) will strive to create an output file with the specified aspect ratio. This feature is especially important if your source files come in various formats or have differing frame rates.

By default, mkvmerge(1) sets the ‘date’ segment information field to reflect when multiplexing began; with this option set as True or False, this date field will now reflect your desired value while changing timestamps accordingly.

Normal use of mkvmerge(1) will produce cue data which allows precise seeking by some players, but disabling this feature will decrease file size while making multiplexed file slightly slower and less accurate when seeking.

MKV Info

MKV Info is a free software program that enables you to add or extract files from MKV videos, split/merge them, edit metadata, support multiple audio formats and subtitle formats, as well as convert other containers to MKV format – without recompression for maximum video quality! Thanks to an active developer community it is regularly improved.

Before using MKV, it’s essential that you gain an understanding of its workings. MKV is a container format which supports multiple audio and video tracks and codecs – making it an excellent way of storing high-quality videos; however, there may be certain drawbacks you should be wary of.

MKV files may not be as compatible with devices and media players than other formats, and can consume more memory, thus increasing overall file sizes. Furthermore, MKV doesn’t support as much metadata compared to some other file types – these issues could present difficulties for those wishing to watch their favorite films on portable devices.

To use MKV, a Linux system with root access will be needed. Once this has been accomplished, download and install MKVToolnix software: it features both command-line tools as well as graphical user interface for editing MKV files.

MKVToolnix is an open-source suite of tools for manipulating Matroska (MKV) and WebM files on Windows, macOS and Linux systems. These include merge, extract, info andpropedit, among others – designed specifically to work together and provide comprehensive solutions when dealing with these formats. mkvtoolnix-gui is a Qt-based GUI for the mkvmerge, mkvinfo and mmg utilities and is used to create, alter, inspect and multiplex Matroska files. Additionally, its implementation of multiplexing, editing chapter information and managing attachments as well as multiplexing functionality is supported. Mkvtoolnix-gui provides online documentation via its documentation homepage – MKVToolNix Homepage.

MKV Extract

MKV Extract is an open-source software solution for extracting audio and video tracks from Matroska files, with the capability of processing multiple files at the same time. It supports multiple file formats and codecs, making it an excellent choice for video editors as well as multimedia enthusiasts. With its intuitive user interface and ability to fine-tune output for specific project requirements – including codec and bitrate settings for optimal audio quality – MKV Extract offers an ideal way to remove audio/video tracks quickly from Matroska files.

MKV Extract’s user-friendly interface enables users to create custom presets that save both time and effort when creating new files, automatically detect audio output settings that produce high-quality results, split videos into smaller segments, then combine them back into one file – perfect for multimedia professionals and hobbyists alike! MKV Extract is also free download, making it an invaluable asset in multimedia production and creation environments alike.

MKVToolnix is a collection of open-source tools (mkvmerge, mkvextract, mkvextractinfopropedit and mmg) for manipulating Matroska files in various ways. You can use it to add or remove audio tracks, subtitles or chapters from an existing file; split one large MKV into several smaller ones; or extract and add audio and video data from files of various formats such as AVI, Dirac FLV HEVC MPEG, MTS MPEG-2 M2TS and VOB.

Mosu has worked diligently on this feature of mkvmerge for some time and should officially release it with the next version.

This feature allows you to set the duration of a cue point with nanosecond precision. It indicates where in bytes inside Matroska(tm) files the cluster containing your element begins; you can calculate its position by adding cluster_position and relative_position together.

This option prevents mkvextract(1)’s output from including any “codec private” track header elements that contain information about which codec was used to decode a track, such as its CodecID or flags.

MKV Propedit

MKV Propedit is an application for editing and viewing Matroska file metadata, enabling you to create, alter or inspect MKV files as well as other video and audio formats like AVI, MPEG, MP4, Ogg/OGM RealVideo as well as AAC FLAC MP2 MP3 OPUS Vorbis ASS and SSA subtitle formats.

This program supports two commands for editing MKV files:’mkvinfo’ and’mkvpropedit’, both available via command line or GUI interface. ‘Mkvinfo’ provides information about track names and attributes while ‘Mkvpropedit’ allows you to customize particular tracks or headers within MKV files.

These command line tools can help fix MKV video metadata by editing existing files or creating new ones. Such metadata includes episode name, actors, director, scen writers, tagline description release date language cover etc – it is essential that this data be accurate for playback of the video in the desired format.

mkvpropedit can edit multiple tracks simultaneously by selecting them via its GUI or keyboard shortcuts, replacing, adding or removing tags in selected tracks. Selector options available are all, global, track – these options can be determined from reading’mkvinfo’ and/or’mkvpropedit’ commands from command line; all tags will be replaced or added when selecting all while for global and track only changing global tags will take place while for track only changing headers will occur respectively.

MKVToolNix supports multiple platforms – Microsoft Windows (both 32 and 64 bit), Mac OS X and Linux. The program works with many video formats including AVI, MPEG, MP4, Ogg/OGM RealVideo as well as AAC FLAC MP2 MP3 VP9 AC3 VobSub IDX SRT PGS SUP VobSub and IDX subtitling formats – and has full VP9 video codec support that allows for splitting, editing, mux demux merge or extracting MKV files!
