Castle in the Sky Aka Laputa. The Japanese release is nicely filmic but not nearly a perfect transfer but it is reasonably faithful. Plenty of grain though I do wish it was less compressed. Its quite an older scan. Its from 2010 blu-ray.
Castle of Cagliostro from the 2014 Ghibli library. The least scrubbed of all releases and still the frozen grain and DNR is garbage. Its either put up with this the even worse 4K, or the 1080i blu ray from 2008 with edge enhancement to make it seem like it is more detailed. the Discotek 4K is probably the least worst of the options because you get multiple language tracks in English and Japanese and subtitles not dubtitles or so I’m told.
And to round it The Cat Returns which isn’t a film transfer at all. Very nice image quality not quite up to Ghibli feature quality this is more like an OVA. that is 75 minutes.
I think I’d like to watch Princess Mononoke next. Though I was thinking of Porco Rosso, and Whisper of the Heart.
