MKVToolNix is a multiplexer that can demux and mux data. You can extract and merge codecs within the GUI. New files can be created from the processes of splitting the content. There are plenty of options to edit while you inspect the properties. The software lets you split a single record up into numerous files to easily access the preferred part. You can extract the different elements from the files: audio, subtitles, and video. The app can embed multiple subtitles into the media in different languages: Arabic, English, Spanish, etc.

MKVToolNix completes the tasks quickly while displaying the progress percentage in the lower right corner. You can import media by dragging and dropping the documents into the ‘Input’ section of the user interface. The information will populate into the different areas of the UI: ‘Source file’ and ‘Tracks, chapters and tags’.

You can drop multiple files at once or only a single file to see the file name, container type, size, etc. The different components of the records will appear in the ‘Tracks, chapters and tags’ area to tell you the multimedia type, codec, language, etc. All of the pieces can be separately selected and unselected depending on your preferred action to keep or remove elements. The GUI lets you adjust the size of the sections by dragging the sides to contract and expand them. You can find the ‘Output’ and ‘Attachments’ tabs next to ‘Input’. The ‘Properties’ section will display the information that corresponds to the selected item in the ‘Tracks, chapters and tags’ list.
