I did see that the dvd for Empire is out, but haven't had a chance to do much with SW stuff lately. Feel free to PM me with the links and I'll check it out as soon as I can. ;)
Since you seem to be very good at lining up frames from different sources, I had an idea about the problematic transition in the Mos Eisley test where the Jabba scene would be. Would it be possible to dissolve between the '04 footage and GOUT before and after this takes place? (Maybe using the '04 dvd instead of the HD for some of it so it's not as big a jump in resolution?) So dissolve to scripted GOUT as the big-nose guy starts towards the camera, allowing the original optical transition to take place, and then dissolve back to '04 before the Millennium Falcon is seen. Would this work? The colour would have to be matched exactly, and the '04 would have to be cropped to match G-force's framing, but it seems like something worth trying. Or, alternatively, a more lengthy portion of GOUT for the whole thing if that wouldn't work. The only other thing I can think of is slowing down the footage to match the original number of frames, but I don't think that would look right at all.
I think I already figured out how to do it using the HD footage only but I'll have to test it to confirm. I want to avoid using the GOUT footage as much as possible but slowing the footage down considerably seems even worse, so if it doesn't work, I think I'll just keep the straight cut.
Well, here it is, the latest attempt of removing the Jabba scene as closely to the theatrical version as possible (2006 DVD is in the lower left corner for comparison). It's not 100% accurate but it's as close as it's gonna get without resolving to using 06DVD footage. This clips also contains new version of the "door is locked" shot.
There is also the shot of Luke selling his speeder with the added ships in the background removed. I tried replacing the whole sky bit but the telecine shake on the 06DVD made it stand out like a sore thumb, which is something I am battling constantly (it's a problem present in every one of the rotoscoped shots to some degree) and I'd really love to know how to do something about it. I tried the stabilizing function in AE but it doesn't seem to work too well on it.
