1600×900 60 fps TV encode.
The Chinese audio track is from a censored release with the puppetgore scenes cut out, so I spliced in silence. Unfortunately, there also seems to be no easy way to do this without reencoding the audio, so I did that. (It's possible to muck with Matroska timecodes to insert delays, but mpv uses audio timecodes for ensuring synchronisation, so this would break playback in mpv.) The Japanese audio track has no issues, of course.
