BD quality is “fine”. The show is razor sharp, both in lineart and noise, making it difficult to encode without bitrates spiking very heavily. However, this also makes it hard to denoise as stronger denoising must be applied to deal with the sharp noise, which can in turn kill background detail quite readily. Besides the aliasing and noise, there aren’t really any other apparent issues.

Filterchain includes denoising (tackling only high frequencies and nuking those, which helped prevent detail loss in the backgrounds), decsize, supersampling + eedi3 to deal with the lineart, weak chroma warping to help realign the chroma a bit in certain shots, and weak debanding. The lineart was also forcibly widened using a very weak awarpsharp with negative values. See comp for how it looks.

Requests are welcome, but don’t count on me to follow through with yours from the get-go.
