It is a standard format (ISO \/ IEC 14496-14) and it is a container format for multimedia tracks. In other words, this format defines how audio and video tracks (called data streams) can be contained in the file in various formats, and can even contain subtitles as well.","thumbnail_url":"http:\/\/mp4gain.com\/mp4gain\/wp-content\/uploads\/2020\/03\/mp4-format-1.png"}
