@Swift S. Lawliet:
I have now EP 4, 5, 6, 7 of the russian extended versions; quality if low, are only in Russian, extended scenes are untouched and not all present, some could be uncorrectly placed (for example the Wampa attack on EP5); nevertheless, they could be used as rough guidelines to scene placement; for EP 1, 2, 3, I rely on ADigitalMan extended version, even if, at the time, the BD scenes were not available; benduwan made an ultimate cut of EP 4, and it will be my main guideline; pittrek send me long excerpts of EP 4, 5, 6 with deleted scenes reincorporated, and I’ll follow these, too. At the end, I’ll ask your help to place further scenes.

@nightstalkerpoet:
Yes, it is possible; to achieve perfect results, the reference scene must have the same frame size (NOT resolution); I mean, if the reference has not cropped size, it could be upscaled to HD and used for input; if the scene is similar, but not the same, or has different size, results will vary. Further tests are needed. Any help with locating same/similar shot to use as reference is really appreciated!

@MWilson:
An avisynth script like colourlike, or there are other softwares that could do that. Today I reviewed the EP 6 deleted scenes included in the Rinzler ebooks, and luckily the b&w ones could be not used, as they are uninteresting or alternate takes, BUT the Rancor scene has shots not seen before, that will be great to reinsert! Your chromajig works well, but I think it’s impossible to reach good result with automatic colorize tools… I think that doing manual settings is the only way to go, possibly following a reference image/clip.
