This is the 1080p [Ohy-Raws] release (https://nyaa.si/view/1177896) with soft English subtitles merged in with mkvmerge.
The subs started as an Arabic to English translation Zen Khalil (www.reddit.com/user/feattzen). Myself (Padowu), shinratensei1602 and aalapshah12297 have heavily edited it to correct mistranslations, spelling, grammar, and the general flow of the English.
At this point the translation is pretty passable. There might still be some minor timing and small mistranslations but overall I think this is better than other things currently out there, especially considering that this one pulls bits and pieces from those translations as well. This also translates the OP and some of the onscreen text.
A proper translation by someone who actually knows Japanese would be appreciated though, especially for the next 2 movies...
