Notes on this conversion
This is a full re-encode, and it is worth stating plainly because the opposite is widely assumed. MOV and MP4 are closely related containers, so many tools can swap one for the other by rewriting the header and leaving the streams alone. This conversion does not do that. Video is always encoded to H.264 and audio to AAC, at CRF 23 by default or CRF 18 on the high preset. Two things follow from that. A MOV that already holds H.264 and AAC is still decoded and encoded again, which costs both time and a generation of quality. And a MOV holding ProRes or another editing codec — the usual reason to convert one at all — comes out as an MP4 that ordinary players, browsers and phones can actually open.

Frequently Asked Questions
Is this just a container change?
No. Video is re-encoded to H.264 and audio to AAC every time. Nothing is copied through untouched, even when the source already holds exactly those codecs.
What does the high preset change?
It moves the encoder from CRF 23 to CRF 18, which keeps more detail and produces a noticeably larger file. Everything else about the conversion stays the same.
Why convert a MOV that already plays on my machine?
A MOV out of a camera or an editor often holds ProRes or another editing codec that browsers and phones will not play. Re-encoding to H.264 inside an MP4 is what makes it open everywhere.
