For characters, the Netflix source is pretty unbearable with terrible encoing artefacts. To hopefully remove the artefacts and return the character lines to what it should be, we use very strong `vsdenoise.bm3d` to denoise, followed by a medium strength AA. After that, we apply `vsdehalo.edge_cleaner` and `vsdehalo.dehalo_sigma` to remove as much halo as we can without damaging the white lustre in some cuts. For background, we use `vsdenoise.mc_degrain` followed by a very conservative `vsdenoise.bm3d` to remove temporal noise. Then, we join with the character for the same AA. After that, we use strong `vsdehalo.fine_dehalo` for dehalo. For encoding, we use Progression Boost Preset-Character-Boost-Butteraugli-Max to achieve a good quality across the whole episode. We use 5fish's SVT-AV1-PSY v2.3.0-C `--tune 3` for the encode. Specifically for characters, we use Progression Boost's Character Boost feature to specifically boost the characters using ROI maps and `--crf`, and we use `--complex-hvs 1 --psy-rd 1.5 --spy-rd 2` to hopefully retain all the fine lines. For high motion scenes, we use `--filtering-noise-detection 4` to avoid artefacts. For background details, we use `--variance-boost-strength 3 --variance-octile 3` and we use strong `--qp-scale-compress-strength 5.5` for better interframe consistency. With Character Boost and various optimisations in Progression Boost, metric result is not very representative of the actually quality. However, as a reference, this is the SSIMU2 score of episode 01 encode with `--photon-noise` removed compared against the filtered source: * SSIMU2 Mean: 90.405 * SSIMU2 5th Percentile: 86.806 The encoding information above is for episode 01, 02, and episode 07 to 13. Episode 03 through 06 was encoded using an older version of Progression Boost and with an ever so slightly worse set of parameters. The quality is not very far from the current encoding script, which is why they aren't reencoded. The details for those episodes are available here: [https://nyaa.si/view/2013935](https://nyaa.si/view/2013935). 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. You are welcome to join AV1 weeb edition at [https://discord.gg/83dRFDFDp7](https://discord.gg/83dRFDFDp7). You are welcome to do anything with this encode, including remuxing and republishing it.
