That's what I thought as well... but there is a distinction between the two in ffmpeg.
A couple of differences I observed between using -f mp4 and -f mov:
- ftyp contains different brands (qt vs. isom)
- mov has an extra hdlr atom under minf
- audio tracks have chan & wave atoms in mov
You can see the differences by looking for 'track->mode == MODE_MOV' in movenc.c
