Part 1. Information About MKV & AVI

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 Matroska Multimedia Container is an open-standard, free container format. Like other containers such as MP4, AVI or ASF, the MKV format contains a large number of video, audio, picture or subtitle tracks in one file. But MKV is entirely open in specification. It serves as a universal format for storing common multimedia content like movies or TV shows. MKV files can be played on many media players like Zoom Player, PotPlayer, MPlayer, GOM Player, and ALLPlayer. But you cannot play it on car infotainment systems, so if you want to play movies for family travels, the first thing you should do is convert MKV to AVI.

AVI is a multimedia container format introduced by Microsoft, and it can hold both audio and video data in a file container that can synchronize to play audio and video. AVI is a derivative of the Resource Interchange File Format (RIFF), which divides a file's data into blocks, or "chunks." The AVI file takes the form of a single chunk in a RIFF-formatted file, which is then subdivided into two mandatory "chunks" and one optional "chunk." AVI is a video format supported by most portable devices and programs.

To learn more about the advanced reasons and advantages of converting MKV to AVI, make sure to read the difference in the codecs of each tool.

H.264 vs Xvid for AVIs

Both H.264 and Xvid are compression and codec options used for handling AVI formats. H.264 is the newer and more efficient video compression standard. Meanwhile, Xvid is the more dated option, but it has superior compatibility for legacy hardware such as DVD players. Because of its higher compression efficiency, H.264 has a much smaller file size.

What are Video Codecs

Video codecs are hardware or software options made for compressing video files. Depending on your codec of choice, your video will be compressed efficiently by removing redundant data, which will allow you to stream or store files much more efficiently. To make modern MKVs compatible with older hardware, you can re-encode or remux AVIs using Xvid codecs.
