The DCP is 1988x1080. A: Sort of, but not exactly, let's talk about chroma subsampling. 99%+ of video you see uses the color(chroma) planes at half resolution in order to save space/bandwidth, generally denoted yuv420p, with the "20" indicating that. "44" indicates no subsampling. Ex. UHD Blu-ray or WEB source: Y(luma)(brightness): 3840x2160@10/8-bit U(Chroma)(color): 1920x1080@10/8-bit V(Chroma)(color): 1920x1080@10/8-bit HD Blu-ray or WEB source: Y(luma): 1920x1080@8-bit U(Chroma): 960x540@8-bit V(Chroma): 960x540@8-bit HD DCP (this one's source)(It's technically XYZ12le, but no one knows what that is, so pretend it's YUV444p12le) Y(luma): 1998x1080@12-bit U(Chroma): 1998x1080@12-bit V(Chroma): 1998x1080@12-bit This Release: Y(luma): 3840x2072@10-bit U(Chroma): 1920x1038@10-bit V(Chroma): 1920x1038@10-bit This release scales the luma up to 3840x2076@10-bit, and the chroma planes down to 1920x1038@10-bit. Q: Why not just encode yuv444p10le? A: Let's talk about AV1 decoding profiles: The profiles range from 0-2(Main,High,Pro), with 0 being the main profile, and the others getting more complex. With 0 being the minimum for certification, 99%+ of devices only support accelerated decoding for the Main profile. https://en.wikipedia.org/wiki/AV1#Profiles So basically nothing other than a beefy computer can decode 1080p+ yuv444p10+, and I don't think SVT-AV1 supports it either. SCP-2223 actually made one if you want it here: https://nyaa.iss.one/view/1764764 Note that it's yuv444p12le, which is Profile 2 (professional). It is unlikely that any hardware acceleration exists for that. Q: Doesn't Nyaa prohibit upscaling? A: Only for certain defined sources, and leaks are specifically exempted from that rule (most likely for weird cases like this).
