Thank you for downloading our encode! Thanks to 动漫国字幕组&白月字幕组 for allowing us to mux in their wonderful 中文 subtitles. slow.pics compare: https://slow.pics/c/e3OUqwU6 This anime is descalable. The original upscale is aligned to the centre of the edge pixel. We descale via Lanczos(2) to 1920*(1552-1)/(1920-1) × 1080*(873-1)/(1080-1) , limited by line mask to avoid damaging texture, and protected by credit mask and various other masks. In addition, the post colouring antialiasing in the original production frequently failed on areas with darker background colour. This is especially common in the lineart on school uniform. During the descale, we perform an AA on doubled using vsaa.based_aa . This AA only applies on darker areas of the character via a character mask using anime-segmentation model and a luminance mask, and doesn't touch anything else. This fixes a good portion of the remaining aliasing. Noisewise, the JPBD has heavy noise. We believe it isn't artistic, so we try to remove as much as can be safely removed. However, on the other hand, some texture in this anime is extremely weak, and being weaker than the noise, they are very temporally unstable. We denoise via mc_degrain + bm3d on luma, adjusted via a character mask via anime-segmentation to apply much weaker denoise on background than chararcter, and we denoise via mc_degrain + wnnm on chroma. After the base denoise above which is shared with the main encode, in the mini, we first remove some invisible information in very bright area via vsdenoise.decrease_size And then to achieve better weak lineart retention in mini, we use MVTools temporally stablise the noise in the source and deband as much as possible. This is performed by feeding MVTools.degrain with a very light denoised and debanded clip with placebo_deband as fallback, and a deband only clip as main. The encode is performed using Apr 28 version of 5fish/SVT-AV1-PSY via vsmuxtools . We use --preset 2 --crf 24.40 --lineart-psy-bias 6 --texture-psy-bias 3 as a base, --hierarchical-levels 4 --balancing-luminance-lambda-bias 0.5 and brand new quantisation optimisation pararmeter --psy-bias-optimize-b 1 for better weak lineart retention in addition to existing features of --lineart-psy-bias 6 , and --dlf-bias-min-dlf 0,0 for better retention given the absence of heavy texture or noise in this anime. We apply a film grain layer with median size grain estimated from a SIMPLEX noise via --fgs-table to this encode. Thanks to comet and other people for guiding me through descale process, and thanks to people on the SeaDex server for pointing out issues with banding. Thanks to all the people creating the tools, plugins and vsfunc’s that make this possible.

We denoise via mc_degrain + bm3d on luma, adjusted via a character mask via anime-segmentation to apply much weaker denoise on background than chararcter, and we denoise via mc_degrain + wnnm on chroma. Due to some texture being too weak to sustain a strong deband, we choose to use a rather light deband via placebo_deband . This is limited by a dctf.DCTFilter based protection to minimise damage on the weak texture, and by a basic vszip.LimitFilter . For encode, we use a decent regrain via vsdehalo.Grainer.SIMPLEX to cover up some light blocking in the original BD. We encode the episodes using x265 4.1+242+57 mod by Patman via vsmuxtools . Parameters: vsmuxtools.settings_builder_x265(hist_scenecut="", crf=11.30, aq_mode=5, aq_strength=0.60) .

More than Kanpeki: This is a high effort filtering and encoding for Kanpekiseijo . slow.pics compare: https://slow.pics/c/RZNAlRmF The BD is lowpassed, and has a thick layer of authoring noise, which results in distortion and sometimes heavy blocking surrounding sharp character lineart. The CR WEB source has much better character lineart. On the other hand, in background, the BD and CR WEB source is about equal. In some scenes, BD has more details, while in other some scenes, CR WEB has more details. We first use anime-segmentation model via vs-mlrt to separarte the character and the background. After that, we delowpass the BD following 12-tap blackmanminlobe with [1/1.250, 1/1.425] fh and [1/1.250, 1/1.375] fv . During the delowpass, we vsdenoise.frequency_merge the BD and WEB. For characters, we take the high frequency information exclusively from WEB to avoid picking up the blocking and dirty mosquito noise in the BD. For background, we add the high frequency information from both BD and manged WEB together. This anime is almost impossible to denoise using typical method. In some scenes, there are multiple layers of texture on top of each other with each layer having different motion. There are also a lot of scenes that fade to black or white. For this reason, we only use a very conservative dctf.DCTFilter and DFTTest to decheckerboard CR prior to delowpass, and we don't perform any denoise on BD. As usual, prior to denoise and delowpass, we perform Lehmer merge on the OP. But to avoid strengthening the checkerboard in WEB, and to limit the noise in BD, we only perform Lehmer merge using a limited number of episodes. Lineartwise, this anime doesn't have much aliasing, but it has quite strong halo, and it's not descalable. We skip AA, and we apply a medium strength dehalo via vsdehalo.dehalo_alpha with mask via vsdehalo.fine_dehalo . To prevent damaging the texture, we only apply dehalo on characters, and we also isolate the noise via DFTTest prior to dehalo. After dehalo, we apply a very light deband on characters using placebo_deband via vsdeband.pfdeband , and then regrain using a layer of Perlin noise on characters to smooth out some of the remaining CR checkerboard. As previously explained, this anime can't be denoised without losing a lot of the texture. So instead we go with the high DLF strategy discovered by Itachi Uchiha and spreaded to my ears by Delie. This method don't hate regrain either, and in fact the regrain seems to have been helping the encoder ignoring the mosquito noise in the source. Although on the other hand, this method isn't very good at producing perfect lineart. We use 5fish/SVT-AV1-PSY Apr 28 version with --preset 2 --crf 24.20 --lineart-psy-bias 5 --texture-psy-bias 4 --noise-level-thr 21000 --satd-bias 0.50 --dlf-bias-max-dlf 24,2 --dlf-bias-min-dlf 16,0 --dlf-sharpness 7 --texture-cdef-bias-max-cdef 0,0,0,0 for the encode. Thanks to all the people creating the tools, plugins and vsfunc’s that make this possible, and thanks to everyone in the community for teaching me, pointing out issues, and giving me advice.

For players such as mpv that support latest HEVC features, we also apply an additional layer of regraining noise via Aom Film Grain Characteristics in SEI message. This is not included in the slow.pics comp due to none of the VapourSynth source filters supporting it. For encoding, we use x265 4.2+6+61 mod by Patman. We use vsmuxtools.settings_builder_x265 default as a base, and set --crf 13.20 --aq-mode 5 --aq-strength 0.45 --aq-bias-strength 1.50 . For NCOP and NCEDs, because there is no WEB to perform delowpass, we skip to dehalo, deband, and regrain, and we use 5fish/SVT-AV1-PSY Apr 28 version with --preset 2 --crf 15.20 --lineart-psy-bias 5 --texture-psy-bias 4 --satd-bias 0.50 for the encode.
