Matroska MKV VS AVI

MKV is a very flexible multimedia container format that can house a wide range of video streams, audio, picture, and allow distributing with extra features such as subtitles and multiple languages in a film. Most videos with .mkv extension contain high-definition H.264/MPEG-4 AVC content, some of them even include H.265/HEVC content. While speaking of AVI format, unlike MKV, AVI had been an industry standard and various of media players and multimedia devices support it. AVI uses Xvid, h.264, mpeg-4 and Mjpeg codecs to encode videos and the resulting file has a reasonable size.
