* -coder and -rc_lookahead will be provided by the x264 preset ("-preset
medium" being the default if you don't explicitly put it in your
command), so in the vast majority of cases you don't need to add these

* "-threads 0" is the default (at least for this encoder, IIRC), so
that's superfluous.

* I didn't see any audio stream in your input, so audio options aren't
needed for this example.

So adding the suggestions from James and Patrick and using your options
could result in:

ffmpeg -i input.mov -vcodec libx264 -crf 35 -pix_fmt yuv420p -movflags
+faststart out.mp4
