Microsoft Audio/Visual Interleaved

File extension .avi
File category video
Description AVI stands for Audio and Video Interleave. It has an extension written as .avi, and users use this same format to store audio and video on their PC, which was developed by Microsoft in 1992 for its Video for Windows project. It allows the simultaneous playback by keeping video and audio into a single file. The simple architecture of .avi format will enable it to run on various operating systems such as Windows, Mac, Linux, Unix. It is supported by multiple web players as well.
Technical details AVI format uses Resource Interchange File Format (RIFF) support, where the real data is stored into chunks, and each chunk gets recognized by a FourCC tag. Out of these individual chunks, the first one can be recognized by the hdrl tag, and it can decode the chunk containing metadata for the video. The second chunk gets identified by the movi tag, and it includes the actual audio and visual data which makes up the AVI movie. It uses less compression rather than the MOV and MPEG file formats.

Matroska Video File

File extension .mkv
File category video
Description MKV Matroska is an open-source multimedia container format that supports more than one audio and subtitle tracks in the same file. It is the most convenient file type where you can add a large sum of data, such as videos, audios, texts, and various images. It is a RAW format which you can later flip and separate based on needed data tracks.
Technical details Whether it is video, audio, subtitle, or image, every file will be stored in a separate data line. It is a lot similar to the MP4 or AVI format, although when users are packaging an MKV file, they rarely bundle all the tracks within the file. Various media players don't even support the MKV video format; therefore, the users need to use specialized media players who can help the MKV format, such as VLC media player.
