Based off of zerocool's DCP remux: https://nyaa.si/view/1761538 Source: DCP Theatrical Master Video: AV1 main profile 0 10bit, crf 29, 3840x2072 yuv420p10le Audio: Japanese - Opus 128kb/s English (1996) - Opus 128kb/s English (Disney) - Opus 128kb/s Subs: English (various) - SSA (nedragrevev) ``` video = core.resize.Bicubic(video, format = vs.YUV444P16) video = core.placebo.Shader(video,shader="AiUpscale_HQ_2x_LineArt.glsl",width= video.width * 2 , height = video.height * 2) video = core.resize.Spline64(video,width=3840,height=2076, format = vs.YUV420P10) video.set_output() ``` master ffmpeg build w/ master svt-av1 build: ``` ffmpeg -i [infile] -c:v libsvtav1 -crf 29 -preset 2 -svtav1-params tune=2:film-grain=50:film-grain-denoise=0:enable-overlays=1:scd=1:scm=2:enable-tf=0:lookahead=120:pin=1:lp=12 -g 1440 -threads 16 [outfile] ``` 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'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.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).

"The rules technically say I can do it, so I'm safe" is a good strategy in the real world, not on nyaa with its unpredictable moderation and bans.

interestingly, the rules don't ban upscaling. they just put resolution limits on certain sources.

Most ai upscales make me want to kill myself.

> Most ai upscales make me want to kill myself. Then you'll be pleased to know this is simply an AI interpolator upscaler (Think like Madvr NGU). It does not fuck with the picture at all. > comp where Against the DCP or the BD? This was linked in another thread (DCP vs BD): https://slow.pics/c/K2Re9PHC

Pointless for me, any high res ie 4K is unplayable for me since my main board cpu & G card blew. Also do not need 4K with my AV (etc) hardware set up. (prefer more disc space). Hmmm .. at least it's not a direct BD dump (those I can hardly call fansubs, lol).

> Then you’ll be pleased to know this is simply an AI interpolator upscaler (Think like Madvr NGU). It does not fuck with the picture at all. Lol? You have no idea how NN scalers work. Anyways, this release is pretty pointless as the DCP is worse quality than the official BD release. No reason to uopscale it either.

The DCP looks significantly better to me in the compairson I linked in the comment you replied to. An easy way is looking at the edges of the text in the first image, see the massive luma bleed/blooming on the blu-ray? > No reason to uopscale it either. The reason that the luma plane alone was upscaled is in the description. The chroma planes were slightly downscaled.

i mean the dcp very obviously looks better than bds

Note the actual source of the DCP is a ProRes 422 HD 10-bit master, noted in the DCP xml. So your numbers are somewhat incorrect. Upscaling this doesn't bring any benefit, but filtering it would. Oh well I thought a bloat broken v0 is the highest meme one could achieve.

> Note the actual source of the DCP is a ProRes 422 HD 10-bit master, noted in the DCP xml. So your numbers are somewhat incorrect. I significantly oversimplified, so yes. The actual end result doesn't really change (unless I was going to do something incredibly wierd like 1920x2072 with the SAR set to be correct, which would be a little silly). > Upscaling this doesn’t bring any benefit It allows hardware acceleration without taking the chroma down to half resolution (as explained in the description). And again, only the luma plane was upscaled from the source.
