Actually, I think boris is right. Resolution is not the end-all and be-all of a good transfer. Unless you start with a good print and use good equipment and take some particular care in the post-processing, it is entirely possible to have a wonderful, glorious, 1080p capture of crap.

I have seen raw 2k captures of contemporary 35mm first-generation film that look pretty lame. Anyone who thinks it's as easy as finding film, sticking it in the scanner, pressing a button and hey, presto! you've got yourself a masterpiece, is sadly, hopelessly, irretrievably naive.

That said, I think good results could be had, with enough time and effort. And a little luck.
