Portable MKVToolNix 99.0 Multilingual

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 Notes:
New features and enhancements
* MKVToolNix GUI: the GUI will now remember the last used directory for selecting audio files for playback in "play audio file" program runners separately from any other "open file"-type situations. This directory will also default to `/System/Library/Sounds` on macOS now. Implemented by #6213. * MKVToolNix GUI: executing actions → running programs: added new variables: `MTX_DESTINATION_FILE_BASE_NAME` (the name without the drive letter, path or the suffix; e.b. `/movies/A.new.hope.mkv` → `A.new.hope`) and `MTX_DESTINATION_FILE_SUFFIX` (only the letters after the last `.`, e.g. `/movies/A.new.hope.mkv` → `mkv`). Added examples to all the destination file variables in the popup menu when adding variables in the preferences. Implements parts of #6220. * MKVToolNix GUI: executing actions → running programs: the command-line input widget will now receive focus again after using the popup menu for adding a variable. Implements parts of #6220. * MKVToolNix GUI: executing actions → running programs: the variables will now also be set as environment variables when running a program after a job completes. * MKVToolNix GUI: executing actions → running programs: when using the "Execute now" button for testing the `MTX_…` variables will be set to the current multiplexer tab's values for easier testing. Implements parts of #6220.
Bug fixes
* mkvmerge: if using legacy font MIME types is off mkvmerge will now remap legacy font MIME types present in source files into the current ones. Patch by corticalcode via #6249. * mkvmerge, mkvpropedit, MKVToolNix GUI's multiplexer & header editor: on Windows & macOS the MIME type detection will now use the FreeDesktop.org MIME database instead of falling back to file extension-based guesses. This matches how it works on other operating systems. This fixes e.g. OpenType fonts being detected as the legacy type `application/vnd.ms-opentype` instead of the current IETF RFC, `font/otf`, no matter what the "use legacy font MIME types" settings in the preferences was set to. Fixes #6240 for Windows; fixes #6248 for macOS. Implemented by corticalcode for macOS in #6250. * MKVToolNix GUI: update checker: fixed a potential attempt to read from an invalid memory address if an error occurred when parsing the XML file retrieved from the official MKVToolNix server. * macOS: GUI: the default audio file for program runners of type "play audio file" has been changed to an AIFF file as Qt's Multimedia backend routes through Core Audio which doesn't support WebM/VP8/Vorbis/Opus. Existing configurations will be updated if they point to the prior default WebM audio file. Fixes #6209.
