MOV at a glance
MOV
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.
AC3 at a glance
AC3
Convert to AC3 when the output is intended for surround-capable consumer playback, especially DVD, broadcast, legacy streaming hardware, or home-theater distribution.
It is a strong target for 5.1-compatible delivery where broad device support matters more than lossless fidelity.
For mastering or archival preservation, lossless formats are usually better.
