In other news, if anyone wants these subs for a 1080p preservation, I've just improved the upscaling process and it now produces great-looking results. These will be included in the next release, but I don't know of any critical need for 1080p subs right now, so unless I hear otherwise, I'll sit on them until I get some more changes.

Well, I think, now that Team Negative1's 35mm preservations are around the corner, those 1080p subtitles would come in handy for those preservations. :)
