Developed in Russia in 2002, MKV is a container format that stands for Matroska Video, taking the name from Russian nesting dolls or ‘matryoshka’. MKV is rare in video file formats as it is completely open-source, and has wide support for integrated non-video elements, such as chapters, selectable video or audio streams, or subtitles embedded in a single file.
Audio Video Interleave or AVI files are a popular video container created by Microsoft in 1992 and are the standard across Windows machines. AVI is often used to save uncompressed, or lossless video, but because of this AVI files tend to be very large - 2-3 GB for every minute of video. AVI files are one of the few container formats that support alpha channel, or transparency.
You might want to convert MKV files to AVI because AVI is more widely supported than MKV and that AVI often has better image quality because it is uncompressed - but be aware that converting compressed MKV files to uncompressed AVI will not ‘restore’ the data that was lost during the compression that took place when the MKV files were originally created, and you will simply be inflating the file size with no image quality improvement.
NOTE: It's important to distinguish between file container formats and compression formats, or codecs. For example, MP4 is a container, and can hold different types of video compression, for example, MPEG-2 Part 2, MPEG-4 AVC, or HEVC, as well as audio (again compressed in a variety of formats) and metadata (for example subtitles). Some codecs can be wrapped in multiple different containers. Containers are sometimes referred to as file extensions, e.g. MOV, MP4, or AVI, but it's important to remember that there can be different types of video within these file formats.
