If you have ripped your DVD movies to ISO files or have some DVD ISO image files downloaded from the Internet and now want to convert ISO to MKV videos so that you can easily share the movies or play the movies on some media players, then you are definitely in the right place here. In this guide, I am going to introduce how to rip ISO to MKV videos with professional ISO to MKV converters at high speed.

Part 1: Brief Introduction to ISO and MKV

What is ISO?

An ISO file, often called an ISO image file, is a single file that's a perfect representation of an entire CD, DVD, or BD. The entire contents of a disc can be precisely duplicated in a single ISO file saved on your computer. All ISO images end in the file extension ISO, and are often used to distribute large programs over the Internet due to the fact that all of the program's files can be neatly contained as a single file.

An ISO image file is generated when people rip a DVD or Blu-Ray disc, and it's an archive file which contains all the stuff in the disc. When we download movies from internet this kind of file format is pretty common, especially for some special versions such as collecting several bonuses or interviews, etc. In this situation a single video file cannot display these stuffs well, that's why the uploaders prefer the ISO format.
How to extract ISO Files? If you don't want to actually burn an ISO file to a disc or USB storage device, most compression/decompression software programs like the free 7-Zip and PeaZip programs, will extract the contents of an ISO file to a folder.

What Is MKV?

The Matroska Multimedia Container is an open standard free container format, a file format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. Matroska is similar in concept to other containers like AVI, MP4, or Advanced Systems Format (ASF), but is entirely open in specification, with implementations consisting mostly of open source software. Matroska file extensions are .MKV for video (with subtitles and audio), .MK3D for stereoscopic video, MKA for audio-only files, and MKS for subtitles only.

The most significant advantage of MKV video is that it can hold unlimited streams (like multiple Video, Audio, Subtitle tracks) into one single file. It is just like a DVD navigator built in MKV file, which can make you enjoy advanced cinematic extras such as multiple audio tracks (e.g. director's commentary), multilingual subtitles, bonus content and more. The only pity for MKV is that it does not support menu and chapter selecting like other video formats.

Nowadays, many media players have been able to play back ISO file and MKV files directly on computer, such as VLC media player, Leawo Free Blu-ray Player, etc.

Part 2: Why Do We Convert ISO to MKV?

Being an optical image, ISO files are mostly found in discs, and have to be burned into another disc. It is the file format usable with a lot of DVD and CD players, especially the ones connected to the home entertainment system. While the MKV format is mainly obtained from streaming media sources. People who are fond of downloading movies and transferring them into a disc are most likely to use the MKV video file format.
Before experiencing how to convert ISO to MKV, it is necessary for us to figure out why we convert ISO to MKV. We choose to convert ISO to MKV for the following reasons.

  • MKV is open source, making the code freely available to developers around the world, which offers an arguably higher potential for more creative solutions and broader implementation.
  • Converting ISO image to MKV makes you enjoy advanced cinematic extras such as multiple audio tracks (e.g. director's commentary), multilingual subtitles, chapter points, bonus content and more as it is like a DVD navigator.
  • MKV is the utmost output format to preserve the video quality.
  • After ripping ISO to MKV on Mac you can even use your Windows Media Player or QuickTime to playback MKV video.
