原盘画质较好,原生分辨率为 720p,采用了较为柔和的拉升算法。线条有轻微的拉升带来的锯齿和振铃,部分平面有轻微的色带,而且噪点在编码时被压成了块状。对于线条部分,我们对画面进行逆向拉伸再重构之后,进行了常规的去振铃处理。对于平面部分,我们进行了常规的去色带之后,削弱了原盘难看的噪点,并替换为同等强度的动态噪点,以改善观感。
The image quality of the source is good with a native resolution of 720p, which was upscaled by a soft algorithm, resulting in slight aliasing and ringing of the lines. And some flat areas feature slight banding with block-shaped noise caused by bad encoding. For the lines, we applied routine de-ringing after descaling and reconstruction of the image. For the flat areas, we applied conventional de-banding and then weakened the unsightly noise while replacing it with dynamic noise of the same intensity to improve watching experience.
