MainVC1VideoProfile.DifferentialQuantization Property

Gets or sets the DifferentialQuantization value for the VideoProfile. Differential quantization (DifferentialQuantization) is a form of perceptual optimization where the amount of compression is varied on different parts of the frame. DifferentialQuantization enables macro blocks containing smooth or dark areas to be encoded at a quantizer level lower than the rest of the image, yielding more accurate encoding of details in those macro blocks.
