The BluRay of 'Okusama ga Seitokaichou!' Season I is of the worst image quality that year. Its effective resolution is only about 540p (960x540) and is terribly upscaled during mastering, which introduces ringing, haloing and aliasing into the image. Even with artificial noises, the banding cannot be concealed. Thanks to the VCB-Studio's newly developed anit-aliasing and dering algorithm, we managed to achieve a decent visual quality. So we revised the Season I to make it better. The Season II is different from Season I, which do not have much artifacts, so no comment is needed here.
