Format description

A MID (or MIDI) file describes music data in the Musical Instrument Digital Interface technical standard. Unlike other audio formats like MP3, it specifies the individual music notes, their duration and loudness, as well as the instruments used. Because of that, a MIDI file may sound differently on different systems.
In order to make it consistent, you can convert it to another audio format.

File extension	.mp4
Category	Video file formats
Developed by	MPEG (Moving Picture Experts Group)
Mime type	video/mp4

Format description

MP4 (short for MPEG-4 Part 14) files store multimedia - video, audio and subtitles. Websites frequently use them for displaying videos because the MP4 format is universally supported.
However, newer video formats, such as WebM, produce smaller file sizes with almost no quality loss. Therefore, you can free up storage by converting your videos to WebM.
