MKVToolnix Portable is a powerful and easy-to-use software application for creating, editing, and inspecting Matroska multimedia container files, also known as MKV files. This free and open-source tool, developed by Moritz Bunkus, supports a wide range of video, audio, and subtitle formats, making it an essential utility for anyone who works with digital media.

One of the most notable features of MKVToolnix Portable is its ability to combine multiple input files into a single output file. This means that you can merge several video, audio, or subtitle tracks from different sources into one file without having to re-encode them. This feature is particularly useful when dealing with movies or TV shows that come in separate files for each episode or with multi-language tracks that need to be muxed together.

MKVToolnix Portable also allows you to extract specific tracks from an existing MKV file and save them as separate files. This is handy when you only need one particular language track or want to extract the subtitles for translation or editing. Additionally, the software lets you edit the metadata of MKV files, such as title, author, description, and cover art, which can be useful for organizing your media library or sharing files online.

Another important aspect of MKVToolnix is its support for various video and audio codecs, including H.264, HEVC, VP9, AAC, AC3, DTS, and FLAC, among others. This means that you can work with high-quality video and audio files without losing quality or compatibility issues. Furthermore, the software offers advanced options for adjusting the video and audio parameters, such as bitrate, resolution, framerate, and channel layout, giving you full control over the output quality and size.

In addition to these core features, MKVToolnix includes several other tools that can be useful for advanced users. For example, the “mkvmerge” command-line tool allows you to automate the process of muxing and demuxing MKV files, which can save time and effort when dealing with large batches of files. The software also includes a “mkvinfo” tool that displays detailed information about the structure and contents of an MKV file, such as the number and type of tracks, the duration and size of each segment, and the compression method used.

Overall, MKVToolnix Portable is a must-have tool for anyone who works with digital media in the Matroska format. Its intuitive interface, comprehensive features, and robust performance make it an excellent choice for beginners and professionals alike. Whether you need to merge, extract, or edit MKV files, or just want to explore the details of your media content, this software has you covered. Best of all, it’s completely free and open-source, meaning that you can use it without any restrictions or licensing fees.

Inspect and manipulate Matroska files

The tool enables you to view, append and take apart tracks, chapters and tags, as well as to edit a wide range of data. For example, when it comes to general track options, you can set the track name, language, default and forced track flags, tags, and timecodes.

What’s more, you can set the aspect ratio, FPS, delay, stereoscopy mode, cropping, cues, compression mode, and custom command-line parameters for enhanced functionality. External files can be embedded in the movie as attachments.

Create and edit movie chapters

It’s also possible to create chapters and define properties, such as start and end time, flags, segment and segment edition UID, together with chapter name, language and country. Configurable global settings focus on the tag file, whether to create a WebM compliant file or not, split mode, file linking, and so on.

An important aspect worth taking into account is that MKVToolnix Portable offers support for batch jobs, which means that you can leave the workstation unattended while the tool executes time-consuming tasks.

You can examine the current command line and copy it to the Clipboard or save it to file to use in future projects, manage the queue jobs, add command-line options, load chapters from external files, edit the header, as well as save the project as an .mka, .mkv or .mk3d-formatted file.

Release Note:

## New features and enhancements

* mkvmerge: Matroska reader: the "video alpha mode" track header property will be copied to the output file if present. Part of the implementation of #3643.
* mkvmerge: Matroska reader: the "video alpha mode" track header property will be reported in JSON identification mode as the track property `alpha_mode`. Part of the implementation of #3643.
* mkvmerge: Matroska reader: the file's timestamp scaling factor will be reported in JSON identification mode as the container property `timestamp_scale`.
* mkvmerge: MPEG transport stream reader: teletext subtitles intended for hearing impaired people (type 0x05) are now marked as such via the appropriate flag in the track headers.
* mkvmerge: file identification: the JSON identification output schema version has been bumped to 19.
* mkvmerge: added a new hack `always_write_block_add_ids` that can be used as a workaround for players that don't support the handling of missing "Block Addition ID" sub-elements of "Block More" elements in block additions properly. These are used for e.g. alpha channel data in VP9 with a "Block Addition ID" value of 1, which is also its default value. Workaround for the player issues listed in #3643.
* mkvinfo: added support for the "video alpha mode" track header element. Part of the implementation of #3643.
* mkvpropedit, MKVToolNix GUI's header editor: added support for the "video alpha mode" track header property. In `mkvpropedit` it's called `alpha-mode`. Part of the implementation of #3643.
* MKVToolNix GUI: multiplexer: when adding files the GUI can automatically enable the "hearing impaired" flag for audio and subtitle tracks if the file name contains the word "cc" or "sdh" delimited by certain characters (configurable). This feature is turned on by default. Implements #3648.
* MKVToolNix GUI: multiplexer: when scanning for Blu-ray playlists the GUI will now ignore playlists that are likely meant for menus. Currently the GUI considers this to be the case when a playlist contains the same item at least five times. This behavior can be turned off in the preferences. Implements #3658.

## Bug fixes

* mkvmerge: MPEG transport stream reader: fixed a crash introduced in v81 that occurred when there was at least one PCM track that wasn't copied from the transport stream file. Fixes #3645.
* mkvmerge: when reading data from Matroska files damaged in a specific way, mkvmerge ended up trying to write various types of elements that aren't allowed to be written (so-called `EbmlDummy` elements as well as elements that don't have a value set) to the output file, which caused the underlying `libebml` library to abort. These types of broken elements are now filtered out.
