I am not sure.  But the files do play on Windows, just not straight
from the browser.  I have to download them first and then play the
file from disk.

I checked for vbr in the man page and did not come up with
anything. I did activate the -hq settings, and cobbled the rest of the
options from other posts to get a file which looks better. Below are
the lines from my script (probably I am doing something stupid?).

How do I turn off vbr ?



rate="-r 15"
pass="-passlogfile ffmpeg.log -pass" 

opts="-hq -naq -lumi_mask 0.07 -dark_mask 0.2" 
out="-pix_fmt yuv420p -r 30 " 
codec="-vcodec mpeg1video" 
size="-s 320x208 -y -b 350"

ffmpeg $rate -i $1 $size $opts $out $codec $pass 1 $2.mpg
ffmpeg $rate -i $1 $size $opts $out $codec $pass 2 $2.mpg
