Shiki [BD 1080p; HEVC Main 10; Opus]

The video source is Moozzi2's 1080p BD raw, whereas the chapters are from Elysium and the subtitles are from Taka and Umee.

Transcoded on Arch Linux with the following fish script, whereby I am now passing "-x265-params "bframes=8:subme=5:rc-lookahead=60:weightb=true" as additional parameters for the slow preset.

<br></br>#!/usr/bin/fish<br></br>mkdir ../Transcoded ../Original<br></br>for episode in (find . -type f -name "*.mkv")<br></br> echo Transcoding $episode...<br></br> ffmpeg -i $file \<br></br> -pix_fmt yuv420p10le \<br></br> -map 0 -c copy \<br></br> -c:v libx265 -preset slow -crf 18 \<br></br> -x265-params "bframes=8:subme=5:rc-lookahead=60:weightb=true" \<br></br> -c:a libopus -b:a 128k \<br></br> ../Transcoded/$episode<br></br> and mv $episode ../Original/$episode<br></br>end<br></br>

Pondering increasing the tu-{inter,intra}-depth and disabling SAO for the next transcode.
