MKVExtractGUI is an application which proves to be extremely useful when it comes to demuxing MKV files. This video format can contain multiple audio and subtitle tracks, for example, and they have to be extracted with the aid of a third party tool. This app does this and it also provides support for other tasks which are accessible through the main menu.

MKVExtractGUI has a basic interface that contains just a few buttons, so that users can easily achieve the tasks they have to. First of all, an input video file must be chosen and users can drag and drop it or browse to its location. After this is done, the other options become available, such as the extraction tools. Audio and subtitle tracks can be selected one at a time or altogether.

MKVExtractGUI allows users to also extract attachments and timecodes from within the MKV file. These can be exported into TXT or HTML files. Extracted content does not have its quality altered so that high quality outputs are available. The demuxing process requires a low amount of resources and users can also queue multiple tasks and allow the tool to solve them automatically with identical or different parameters.
