How to convert MOV to MP4 on a Mac
Built in: In Finder, right-click the video → Encode Selected Video Files. It makes a .mov or .m4v rather than an .mp4.
With Garlic
- Start dragging the MOV files from Finder.
- Hold ⇧ Shift — the garlic opens under the pointer.
- Drop on MP4. The MP4 appears beside the original.
For a smaller file, drop on HEVC (about half the size) or 720p instead.
