Video

The only source with correct color grading is the 2007 Sony disc (identical video on all regions). This has been verified by comparing it to production material shared by the director, and can also be seen in video histograms. This new grading seems to be a result of range expansion and is strongly red-tinted throughout. The newer master also appears to have extra haloing not present on the Sony disc.

Unfortunately, the 4K remaster from GKIDS looks plainly bad. It's a result of destructive filtering applied to the new master (especially pronounced when comparing the 4K disc), only adding to its issues, with all lineart turning out smeary and noisy.

Sony is an English localized master, though all this amounts to is credits and a few signs. GKIDS is bilingual, all other releases are in Japanese. A comparison between the different language masters can be found here.

Audio

Japanese audio is pretty much the same across the board, with the only difference being that GKIDS' surround channels are 3 dB quieter. Given that it is common for home releases to forget to adjust theatrical levels to home video, I would wager that GKIDS is correct, but I have nothing to back this up.

English audio is superior on the GKIDS disc, as Sony only had a lossy track, while All the Anime used the same lossy track transcoded to DTS-HD. The same surround levels difference applies here.

As there are 3 fewer frames in the Sony disc, I had to re-encode the GKIDS audio to sync it.

Subtitles

All English subtitles are based on the dub script, made with the director's involvement. Preferred GKIDS as they've edited a couple of lines that didn't make sense with the Japanese audio. Removed on-screen translations as Sony uses an English localized master. Adjusted timing (gaps, snapped to keyframes), removed on-screen translations as Sony uses an English localized master. Included a stylized ASS version, plain SRT, and PGS with color changed from yellow to white.

No forced/signs track was included here, as the Sony US disc did not include one. The GKIDS disc included a forced track for Japanese end credits, which was not needed with Sony's English master. The Sony EU disc included one, but it consisted only of lines like "$%&=):@ $%&=):@ =):$" for spoken gibberish, so I left it out, as neither Sony US nor GKIDS included it as a forced track.
