About the formats

Extension m4a
Category Audio/Music file formats
Developed by Apple
Mime type audio/m4a

Description

M4A files store audio using the AAC codec. M4A stands for MPEG-4 Audio. It is very similar to MP4 with the difference being the lack of a video/subtitle track in the file.
Extension mkv
Category Video file formats
Developed by Matroska
Mime type video/x-matroska

Description

MKV files are MatrosKa Video files. Like the Russian Matryoshka doll, which contains multiple smaller dolls nested inside each other, the MKV format can contain multiple video, audio, and subtitle tracks inside a single file. This makes it convenient to have one video with a number of audio and subtitle tracks in different languages, all inside a single playable file.
