About MOV
QuickTime File Format
Apple's QuickTime container from 1991, which MP4 was later based on. iPhones and Macs record video as MOV, usually with H.264 or HEVC inside. Convert MOV to MP4 for Windows, Android and websites that expect MP4.
About MKV
Matroska Video
An open container first released in 2002 that can hold almost any video and audio codec, plus several audio tracks, subtitle tracks and chapters in one file. Use it to keep multiple languages and subtitles together; convert to MP4 for devices that do not read MKV.
