Format guide
What is MOV?
QuickTime File Format is Apple’s QuickTime media container commonly used for camera video and pro intermediates, created by Apple (1991). MOV holds video/audio tracks (often H.264/H.265 or ProRes). It is native to iPhone and Final Cut workflows; convert or remux to MP4 when sharing with Windows users or uploading to platforms that prefer MP4.
