鬼泣动画的画质算是比较灾难的了,所以处理上反向拉伸至 720p 去做处理,并且画面充斥着大量噪点,想过多种方法去强力降噪,发现越降越差,最后,选择轻抹一层噪点并作适当的 deband 处理,用高码率去保留剩余噪点。 考虑到美版但丁 CV 是 Reuben Langdon,所以主音轨为英语,外挂音轨为日语。
The BD quality is disappointingly poor, with color-banding, aliasing, and heavy film grain. We applied de-bilinear to inverse the video to 720p, then we performed de-banding and partial de-noise to fix the remaining artifacts. Finally we deployed fairly high bit-rate in order to retain the fragile details.
We muxed the English audio-tracks as the main track in the MKV files, and the Japanese ones are attached as external audio. This is because I prefer the vocal by Reuben Langdon in the English tracks.
Reseed comment:
1. Removed the delay tag from main series and inserted silence of equivalent length. May result in different length of US audio and JP video, but won't affect viewing.
2. Revised 3 CM's about DMC 4.
3. Fixed 20ms delay of audio IV.
4. Re-assembled the CD according to new standards.
