Convert MP4 to MOV online
Convert MP4 to MOV when a Mac editing workflow expects QuickTime. MOV and MP4 share an ancestor and are structurally very similar, so this is less a format change than a relabelling with settings tuned for Apple software — H.264 at CRF 23 with yuv420p pixels, which is what Final Cut and QuickTime expect from an imported file.
When should you convert MP4 to MOV?
- Import footage into Final Cut Pro or iMovie
- Hand a clip to someone working entirely on macOS
- Match the format the rest of a Mac project is using
- Fix a clip that opens in VLC but not in QuickTime
Before you convert
It is a re-encode, not a rename
The video is decoded and compressed again, so it costs a generation of quality. Converting back and forth repeatedly will soften the picture.
MOV is not ProRes
Professional Mac workflows often want ProRes inside a MOV. This produces H.264 inside a MOV, which plays everywhere but is not an editing codec.
What happens to your file
MP4 to MOV is a full re-encode, not a container swap: the video is decoded and re-compressed with libx264 (H.264) at CRF 23, preset medium, and the audio is re-encoded to AAC at 192 kbps. Pixels are forced to yuv420p, which is what QuickTime and Final Cut expect from an imported H.264 file.
Settings this conversion runs with
| Engine | ffmpeg |
|---|---|
| Video codec | libx264 (H.264) |
| Video quality | CRF 23, preset medium |
| Audio codec | AAC |
| Audio bitrate | 192 kbps |
What changes
- The MP4 picture is decoded and re-compressed with libx264 (H.264), so this is a generation loss: the output is built from an already-compressed source, not from the original camera data. Converting MP4 to MOV and back will soften the clip a little more each time.
- Only one video and one audio stream reach the MOV file. Additional audio languages, embedded subtitle tracks, and chapter markers are not carried across.
