About MKV
Matroska Video
An open container first released in 2002 that can hold almost any video and audio codec, plus several audio tracks, subtitle tracks and chapters in one file. Use it to keep multiple languages and subtitles together; convert to MP4 for devices that do not read MKV.
About AVI
Audio Video Interleave
Microsoft's RIFF-based video container from 1992. It is mostly found in older camera footage and DivX or Xvid files. Convert AVI to MP4 to play old clips on phones and current players, usually at a smaller size.
