MKV (Matroska) is a flexible open container that holds high-definition video, multiple audio tracks and subtitles in one file. It is popular for movies and archiving, but is not natively supported by every device or browser.
MKV plays in VLC and most modern media players; some phones, browsers and TVs need it converted to MP4 first.
AAC (Advanced Audio Coding) is the successor to MP3, delivering better sound at the same file size. It is the default for Apple Music, YouTube and most streaming services, and is supported across virtually all modern devices.
AAC plays in Apple Music/iTunes, QuickTime, VLC and on nearly all modern phones, browsers and players.
