I should have proof-read better. I have many typos in here, but the
worse is my broken command where I said -ar 2 instead of -ac 2

Also I meant to say that I wasn't sure if downsampling will increase
the volume levels, as I don't know enough about audio .

 So overall, your command would be something like (i haven't tested this):
ffmpeg -i "YDXJ0085.MP4" -c:v libx265 -preset medium -map 0
-reserve_index_space 50k -crf 22 -s 3840x2160 -b:v 10M -ac 2 -c:a aac
-b:a 128k -metadata title="Juliana - Disney 8-12-2018"
