Did you try the other one (the first one) I posted?

>>> ffmpeg -y -i in.mov -filter:v scale=640:-1 -c:v libx264 -preset:v
>>> slow -profile:v baseline -x264opts
>>> "level=3.0:vbv-maxrate=750:vbv-bufsize=3750:ref=1" -b:v 500k -r:v
>>> 25/1 -force_fps -movflags faststart -c:a libfaac -b:a 80k -pass X
>>> out.mp4
