As an important and popular container file format, MKV has been widely used nowadays which has the large capacity to store pictures, audios and videos at a single time. Sometimes, you have obtained a lot of MKV clips which all have similar digital information and you may have the urgent need to share these MKV files with others. Transferring these MKV files one by one is a waste of time. However, if you can merge these files into a single one MKV file, it will be much easier and more convenient to manage and share MKV files. In this article, you will get to know more information about the best MKV merge tools and how to join MKV files with MKVToolNix and other related merge programs.

Part 1: Introduction on MKV File

Matroska Multimedia Container (MKV) is an open standard free container and file format. It is a multimedia package format that can accommodate an unlimited number of video, audio, picture or subtitle tracks in a single file. So, it’s not a compressed format, but a multimedia container file defined by Matroska. The goal is to preserve common multimedia content such as movies and TV shows as a unified format. Conceptually Matroska is similar to other containers, such as AVI, MP4 or ASF (Advanced Streaming Format), but it is completely open in technical procedures and contains many open source software in its implementation. A variety of differently encoded videos and more than 16 different formats of audio and subtitle streams in different languages can be packaged into one Matroska media file. The biggest feature is the ability to accommodate multiple different types of encoded video, audio and subtitle streams.

MKV is different from video encoding formats such as DivX and XviD, and is also different from audio encoding formats such as MP3 and Ogg. MKV is a "combination" and "package" format that provides a cover for these audio and video. In other words, it is a container format. The common DAT (which is an encoding format of VCD) also belongs to this type of AV1, VOB, MPEG, and RM formats. But they are either obsolete or not open enough, which led to the birth of a new multimedia packaging format such as MKV.
