**Description**
The pixelated mess of a release was my main motivation for doing this right. I downscaled the BD and then upscaled it properly resulting in a much better image. All the pixelation is gone and there is no detail loss in the backgrounds. I encoded the original PCM audio to FLAC. The subs and fonts are from Doremi. The chapters are from the BD. This is a larger version of my [516p release](https://nyaa.iss.one/view/1345614).
**Info**
Video: 1920x1032p x264 10-bit
Audio: FLAC 2.0
Sub: Doremi
Chapters: yes
**Tech Note**
The backgrounds were scaled fine but the characters were horribly pixelated from nearest-neighbor scaling. To begin I downscaled the BD to the largest 16:9 resolution that's both smaller than 480p and a multiple of 2. This is because while the original resolution is around 480p, 480p doesn't have a perfect 16:9 ratio. I needed to match the BD since I don't know the exact native resolution. After cropping and encoding to lossless yuv444p 832x448, I extracted all the frames to png. I then used Waifu2x with the CUnet model to double the resolution. I know there are other programs that use Waifu2x specifically for video upscaling but since I haven't inspected their claims for myself yet I played it slow and safe. It only took ten and a half hours with my GTX 1060 6GB, to give a reference point. Finally I encoded the 1664x896 png frames to yuv420p10le 1920x1032 with spline upscaling. For some weird reason ffmpeg treats rgb input as bt601 so I had to convert to bt709. I didn't do a 3x Waifu2x upscale and downscale to 1920x1032 because it looked too artificial. The 2x with spline upscale looks more natural.
TL;DR I fixed the pixelation using Waifu2x
