An MKV file, or Matroska Video File, is an audio/video file format created to store multimedia data in a highly compressed format. The MKV format supports a wide variety of audio and video codecs and is a popular format for distributing video files.

The format itself is a container format, meaning it supports many different audio and video tracks, all using different codecs. Along with audio and video, other data, such as chapters, markers, sub-titles, and other useful data, can be stored within the file.

Support for editing MKV files is widespread, with most video editing applications able to open MKV files. Video playback software, however, can sometimes struggle to playback MKV files if they are not equipped with the correct codecs.

FormatBinary

An MP4 file is a modern standard format for storing high-quality motion video in a highly compact and efficient file size. The specific compression algorithm used within an MP4 file can vary from file to file; however, they all enable what would otherwise be a large amount of uncompressed data to be reduced to a fraction of the original size with little or no noticeable difference in playback quality.

Due to their widespread support, MP4 files can be loaded into most video editing applications and played with most video playback software with no additional drivers. Most video sharing sites, such as YouTube, support MP4 as a format when uploading, and most tablets and smart phones can record in the MP4 format.

Audio stored within an MP4 file is usually stored in the MP3 format, taking advantage of that format's high quality and compression capabilities.
