When MOV is the right output

MOV is Apple's QuickTime container — the native format for iPhone screen recordings, macOS screen captures, and ProRes-encoded footage. Convert to MOV when your destination is Final Cut Pro, iMovie, or Apple's Motion — these programs handle MOV without transcoding. For distribution, always use MP4 instead.
