Comment (by JouMxyzptlk):

 That is a pretty annoying and unexpected bug to skip chapters
 Especially when the console tells me that the chapters are all detected.
 Now I a forced to check my older encodings which were a wasted time.
 Who introduces such stupidness in the code as default behaviour?

 ffmpeg.exe -y -i "%%X" -vf "hqdn3d=4:3:7:6" -c:v libx264 -preset veryslow
 -tune animation -level 5.2 -profile:v high -crf 22 -codec:a libvorbis -q:a
 6  "out1\%%X"

 Output #0, matroska, to 'out1\1.mkv':
