[FFmpeg-user] Long delay on encoded f4v files

I am encountering problems with long buffer times on encoded f4v files once converted using ffmpeg.

When I had been converting them via Adobe Media Encoder manually there was no issue but as soon as I started using ffmpeg to encode I am waiting 5 - 15 seconds for the clips to display (stream/start playing) where previously they appeared straight away.

My conversion command line call is:

ffmpeg -i $in -s 1180x664 -ar 32000 -ab 48k -vcodec libx264 -vpre slow -b 2100k -f mp4 $outFVideo

Is there anything anyone can spot that might be causing the issue or that I could try to improve the situation.  I am new to the world of ffmepg and any help would be gratefully received as the documentation is at times confusing.
