Starting to work on Empire. First step is to find out what frames are missing from each version. The TR47 is missing a bunch, but oddly, so are the NTSC GOUT. ANH was missing one from NTSC vs. PAL and Empire seems to be missing two.
I have all the GOUT version lined up. TR47, GONZO, NTSC GOUT, PAL GOUT, and Hyperspace along with the cut down TB, GKAR, DVD and BR. There were some color changes for the SE, especially on Hoth, so not everything will match, but I'm going to use the PAL GOUT as my guide. Colorwise it doesn't need much, if anything, just some contrast and gamma adjustments.
Where ANH fought me like a tiger for two weeks and I still didn't come up with draft coloring that was satisfactory, TESB, in one day, has yielded a workable color correction for all three versions (PAL GOUT, GKAR, and BR). Now to render and watch and then tweak.
