AVI & MKV are the most common container video formats that contain various digital data, including audio, video, text, etc. 

Despite being a container of different digital data, the format also involves a codec that is meant to compress or decompress data in the format.

AVI (Audio Video Interleave) & MKV (Matroska Video File) are the multimedia container video formats. Microsoft-developed AVI is one of the oldest and simplest video formats that offers standard video quality with compression using DivX, XviD, and MJPEG codecs. 

AVI is mostly used to create and store multimedia content for physical discs, DVDs, etc. This format is best for short films, promotional videos, advertisements, etc. It is compatible with most common media players and devices. 

Despite being the most contemporary video container format, Matroska Multimedia Container, aka MKV, is an open-source and free video format. It contains unlimited multimedia data, including audio, video, metadata, subtitles, etc.

Because of its open-source nature, MKV is widely adopted and the center of continuous development. It is supported by the most advanced codecs, such as H.264, H.265, AAC, VP9, DTS, etc., to offer maximum compression in high quality.
