[FFmpeg-user] having trouble encoding mov to mp4 H.264 level 3.0 baseline for HTML5 iOS

[Antony Peiris]

Thank you, I totally agree that's a lot better. I did not come up with 
the command myself, had some help.

> ffmpeg -y -i in.mov -vf scale=640:-1 -vcodec libx264 -vpreset slow -vprofile baseline -x264opts "level=3.0:vbv-maxrate=750:vbv-bufsize=3750:ref=1" -vb 500k -r 25/1 -force_fps -movflags faststart -acodec libfaac -ab 80k -pass X out.mp4


Tired what you recommend, but this gave me the following error: 
Unrecognized option 'vpreset'.

Have I compiled ffmpeg incorrectly?
