MOV at a glance
MOV
Apple's QuickTime file format predates and influenced later MP4-family standards, which is why MOV and MP4 feel related even when they serve somewhat different operational roles.

Convert to MOV when the destination is an editing suite, a post-production handoff, or a review pipeline that expects QuickTime-compatible containers and production codecs. It is a good target for ProRes masters, camera transcodes, alpha-capable intermediate files, and mezzanine assets moving between creative teams. Choose MOV over MP4 when editorial flexibility, codec support, or production metadata matter more than universal playback. For end-user streaming, downloads, and browser compatibility, MP4 is usually the better delivery format.
