About Matroska (MKV)
Matroska (MKV) is an open container format that can hold almost any video and audio codec, any number of audio and subtitle tracks, chapters and attachments.
It is popular for films and series with several audio languages and subtitle tracks, and for archiving video.
Many phones, browsers and TVs do not play MKV files directly, even when they support the codecs inside.

Why won't my MKV file play on my TV or phone? Most TVs and phones play MP4 or H.264 but not the Matroska container, so converting to MP4 makes the file playable on almost any device.
About AVI
AVI (Audio Video Interleave) is a container format Microsoft introduced in 1992 for video on Windows.
Older cameras, Windows software and video collections from the 1990s and 2000s.
AVI predates modern codecs and has no native support for features such as variable frame rate, so it is rarely used for new video.
Why convert video to AVI today? Mainly for older Windows software and DVD-era players that accept nothing else.
