The frame dimensions and the frame rate are used to determine the Dirac
preset to use in FFmpeg - E.g. if the frame dimensions are 720x576 and
the frame rate is 25 (by default the frame rate is 25 I think) then the
preset of SD576I50 is used. 

If the frame rate does not match any of the preset frame rates the first
preset that matches the frame dimensions is used. E.g. for 1280x720 if
the frame rate is not one of 60000/1001 or 50/1 then the preset HD720P60
is used with the frame rate overridden by the frame rate specified in
the command line. 

If the frame dimensions do not match that of any of the presets then the
CUSTOM preset is used.
