Required when you set Pixel aspect ratio to SPECIFIED. On the console, this corresponds to any value other than
Follow source. When you specify an output pixel aspect ratio (PAR) that is different from your input video PAR,
provide your output PAR as a ratio. For example, for D1/DV NTSC widescreen, you would specify the ratio 40:33. In
this example, the value for parDenominator is 33.
