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 article, I am going to introduce how to rip ISO to MKV videos with fast ripping speed via an ISO to MKV converter.

Part 1: What Is ISO?

ISO image file

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.

When will ISO occur? Well, 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 stuff well, that’s why the uploaders prefer the ISO format.

Where are ISO files used? 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.

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.

Part 2: 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.

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.
