SCY ？没怎么听说过的组，有什么特色或特长？U2上能搜到的不多。
搜到了fate zero，note里竟然说mawen1250的不如Salender-Raws，所以他/她不得不亲自压，并得到了最好的版本。你怎么看？
“Video-wise, Fate/Zero is a bit of a doozy. The BDMV contains an outrageous amount of film grain (the most I’ve ever seen in an anime BDMV), resulting in astronomically high bitrates when attempting to encode it. Episode 15 is particularly brutal. At first I was just going to make a remux using the very best 1080p encodes I could find (which, after a lot of downloading and comparing, turned out to be the 86.4 GB release from Salender-Raws), but upon closer inspection I noticed the encodes suffer from heavy discolorization compared to the BDMV due to very strong chroma denoising. There’s also the complete lack of debanding that made me shy away from Salender-Raws. The second best was mawen1250, but the luma denoising was far stronger than Salender-Raws and there was plenty of artifacting and detail loss from a lack of video bitrate.
And so, I had no choice but to do my own encodes. The heavy amount of film grain makes for an extremely sensitive source, so I stuck with adaptive BM3D denoising and only targeted bright areas to ensure minimal detail loss. Other filtering includes rescaling, insaneAA, anti-aliasing, some chroma denoising, debanding and dehaloing. 1080p credits, signs and logos were all manually excluded from filters that would otherwise damage them. I experimented a couple of hours with x265 but ultimately wasn’t satisfied with the results, so I stuck with x264. Downscaling to 855p didn’t look very good either. Perhaps in a few years from now I’ll re-do these encodes with AV1, as I do think 96 GB for 25 episodes is pushing it (although interestingly enough, x264 still reported a lot of these episodes as not being transparent). If you want smaller files that offer the same quality, I’m afraid you’re out of luck. Any other 1080p release out there is noticeably worse, and there’s not many (if any) great native resolution encodes to choose from, let alone x265/AV1 ones.”
