Long story short, the production of the whole series is about trim and treat. We started with Tsuiokuhen, and first we thought it is a regular HD remaster until in EP04, we found a lot of problematic SD scenes. Some even have serious interlacing issues which should never be seen in a progressive source BD. It is hardly possible to design one scheme that copes well with both HD and SD scenes so we trimed them one by one, used different approaches to fix their problems, and joined them again. For HD scenes, we only performed some grain stabilization to reduce the bit-rate, and for SD scenes, we fixed the interlacing problems, replaced the awful DCT noise with a reconstructed noise layer, and finally we did some de-ringing and line darkening in order to match the visual similarity with the HD scenes. It should be far less obvious to distinguish them after encoding.
星霜篇和追忆篇的问题大体差不多,几乎都是 fullHD 画面穿插 SD upconv 的画面。不过情况比追忆篇稍好,总共也有就 30 来处的 SD upconv 的片段,处理手段大体和追忆篇差不多。不过值得一提的是,星霜篇第二集,有一段由于锯齿已经成了波浪线,几乎无法修复,强力 AA 只会吃力不讨好,所以只能用 DVD 画面带过去。好在画面不长就几秒的样子,对比截图中有一组原盘和成品颜色不一致,就说明是 DVD 代替(DVD 部分线条黑化不是很好,毕竟 DVD 代替时间不长 所以就没有特地调整线条)。 PS:看星霜篇大喊三声这是同人,这是同人,这是同人。
For the Seisouhen chapter, the problem is similar but slightly less severe. However there is one short scene in EP02 with extreme aliasing and I have no idea how to fix it. All I can do was to take the DVD source, trim the corresponding part and then replace the BD portion. The hue of DVD is a bit different from the BD (seen the below comparison) but it should be fine since it's only a few seconds long.
镇魂歌说真的和上面一比,真的是没啥毛病,就是噪点多不利于压缩。 个人已经没有精力去开 TV 版了 所以在合集里放了三个彩蛋,算是补偿吧,看体积应该都能猜出来是啥了。
The last chapter, Ishinshishi e no Requiem, is probably the easiest since the only problem is its heavy noise. This project started long ago when AVC was still the better choice, and we have no plan for the TV series.
Reseed comment: 1. Renamed all files and folders to our latest standards: use Romanization of Japanese wherever possible 2. Changed video track language (JPN -> UND) 3. Moved PGS subtitles from MKA into MKV 4. Trimmed meaningless chapters in the end of the live-action adaptation of Tsuiokuhen and Seisouhen 5. Fixed the audio track order for Tsuiokuhen EP04 in the MKA file 6. Modified the colour matrix parameters for files using DVD sources 7. Trimmed unwanted silence and noise in the audio track for live-action Seisou Hen in the end 8. Added new CDs, and fixed miscellaneous issues found in previous CDs
