23 OCT 2025 - We are back! If you have been following us over the last few years, you will know that the last 2 months have been rough. We website was practically not loading. Sorry for the mess. We are back though and everything should run smoothly now. New servers. Updated domains. And new owners. We invite you all to start uploading torrents again!

Q: Is this an upscale? 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)(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)(brightness): 3840x2072@10-bit
U(Chroma)(color): 1920x1038@10-bit
V(Chroma)(color): 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 Main profile.
https://en.wikipedia.org/wiki/AV1#Profiles
So basically nothing other than a beefy computer can decode 4k yuv444p10+, and I don't think SVT-AV1 supports it either.
SCP-2223 actually made one if you want it here: https://nyaa.si/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).
