About MOV and MKV
MOV: MOV is Apple's QuickTime format and the default for videos recorded on iPhone. Recent iPhones record MOV files in HEVC (H.265), which many Windows PCs and older Android phones can't play.
MKV: MKV is a flexible open container that can hold unlimited video, audio and subtitle tracks. It is popular for movies and anime but isn't supported by iPhone or most TVs out of the box.
