Source: BD AV1 yuv420p10le Opus 128kbit 5.1 JPN Netflix subs (all languages available)(From DragsterPS) If you're going to mux or use one of the international audio tracks from netflix, the BD video is offset by +1654ms vs Netflix, so add that delay to anything netflix based you're trying to mux in. (like the international audio tracks) Commands: ``` ffmpeg -i infile -pix_fmt yuv420p10le -vcodec libaom-av1 -lag-in-frames 25 -g 900 -crf 25 -cpu-used 2 -row-mt 0 -b:v 0 -auto-alt-ref 1 -an -strict -2 -pass 1 -f null /dev/null ``` ``` ffmpeg -i infile -pix_fmt yuv420p10le -vcodec libaom-av1 -lag-in-frames 25 -g 900 -crf 25 -cpu-used 2 -row-mt 0 -b:v 0 -auto-alt-ref 1 -acodec libopus -af "channelmap=channel_layout=5.1" -b:a 128k -strict -2 -pass 2 outfile.mkv ```
