MOV and MP4: same family, different reach
MOV is Apple’s QuickTime format. It’s what iPhones, iPads, Mac screen recordings (⌘+Shift+5) and many cameras produce. MP4 was derived from it and became the universal standard for video: every phone, browser, TV, social network, video editor and learning platform reads it.
So converting MOV to MP4 is usually about compatibility, not quality:
- Upload forms, online courses or CMS platforms that only accept MP4.
- Windows PCs, Android phones and smart TVs that won’t open the MOV.
- Video editors and slideshow tools that expect MP4.
Fast repackaging or re-encoding
A video file is a container holding encoded streams. TurboConvert first checks what’s inside your MOV:
- If the video and audio already use codecs MP4 supports, the streams are copied into an MP4 container without touching the picture. This is fast — usually seconds — and lossless.
- If not (for example ProRes footage or unusual audio formats), the video is re-encoded to H.264 with AAC audio, the most widely compatible combination. This takes longer and depends on your device.
iPhone tips
- High Efficiency vs Most Compatible: in Settings → Camera → Formats, High Efficiency records HEVC video, Most Compatible records H.264, which plays almost everywhere but takes more space.
- On the phone itself: open this page in Safari, tap Choose files, pick videos from your library and find the MP4s in the Files app, under Downloads.
- Files too big to send? Convert and shrink in one step with Compress video — it accepts MOV and outputs MP4.
Common problems
- The conversion is slow. The MOV needed re-encoding (for example ProRes footage from a camera or editing app). A computer is much faster than a phone for this.
- The MP4 is as large as the MOV. That’s expected when the streams are copied as they are. To make it smaller, use Compress video.
