About MOV and WEBM
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.
WEBM: WebM is Google's open video format using VP8/VP9 and Opus. It is built for the web and is what screen recorders and browsers produce.
