原盘画质一般,线条附近有轻微锯齿和一定程度的晕轮,平面有较多噪点和色带。处理上修复了各种瑕疵,并进行自适应降噪和纹理锐化,最后使用 HEVC 编码。
The original image quality is ordinary. There are mild aliasing and some ringing around lines, also noise and colour-banding on flat surface. Pre-processing included anti-aliasing, de-ringing, self-adaptive de-noising, de-banding and texture sharpening. Videos were encoded with HEVC parameter.
