What happens when you convert MOV to MP4
Repackages Apple's QuickTime format into MP4, encoding video with H.264 at CRF 23 and audio to AAC at 128 kbps. The MP4 is written with its index moved to the front, so it starts playing before the whole file has downloaded — the setting streaming sites expect.
Good for
- Making iPhone and Mac recordings play on Windows and Android
- Preparing footage for platforms that reject MOV uploads
- Cutting the size of large QuickTime exports for sharing
Worth knowing
- This is a full re-encode, not a remux, so it takes real time and costs a little quality.
- CRF 23 is a balanced default; visually it is close to the source for most footage.
- ProRes and other professional MOV codecs are decoded and re-encoded to H.264, which will substantially reduce quality for grading work.
