I gave colour matching a quick go last night but it didn't work (the image came out too green or too purple), and right now I'm not sure what I've done wrong.

I dont want to step on the X0 teams toes but I was under the impression that they are not trying to fix the errors I mentioned
Taken from X0's thread
"A possible second version could include fixes to matte lines and garbage mattes, but keep the rest of the "glitches" intact."
I am not up to date on their preservation and if they changed what their intentions were, then just let me know.

We aren't planning to touch the GOUT at this time.

I finally got my ANH GOUT in the mail yesterday, and I saved out two small pieces of it so that I can "dye-transfer" the SE version. I read people on forums say that the GOUT looked kinda bad, but I always thought the screengrabs looked fair enough - but I was really surprised when I watched it in motion today!
I first noticed the wobble that I thought to be impossible:
Whole parts of the image are shaking completely independent of other parts - like some crazy jellovision technology! I guess this must be because this version has applied a noise-suppression-averaging algorithm to the film - before stabilizing the thing. The result is that the bright parts are wobbling about, while the darker parts stays somewhat calm... I take back what I said about the tracking, Laserman. This wobble calls for desperate measures indeed.
And then it seems like the film is interpolated or upscaled in some weird way:
Look at the bright edge on Vaders chest armour, and the bright edge on his right (to the viewer) chin. It's almost like the film has been de-interlaced of sorts? Is this something that is PAL-only, or is this present in the NTSC version as well?
I will try to do the colour-transfer the next time I have a session here at home, but I doubt it will end up like much with the GOUT looking like this...
THX, here are some shots where I haven't retained the black at the SE levels. As you see, there's almost nothing to gain, with the areas ending up with a flat grey instead. It's especially apparent in Greedos face:

Yeah, it is an insane amount of movement, I've had to multipoint track just about every scene I've worked on, and that is *after* a basic stabilisation pass.
Yeah, they upscaled the PAL version from the NTSC letterbox tape, I still can't believe they crapped on the PAL territories like that, especially when they created a separate PAL master for the laserdisc releases. The PAL version consequently has a bunch of awful scaling artifacts.

I'm still unsure why this occurred on the NTSC laserdiscs (and of course the GOUT). I've seen it happen with field based telecine systems, the film moves slightly in the gate inbetween the first field being captured and the second, causing a misalignment of sorts that looks a lot like this effect.

I feel really cheated by this upscale issue, though. I need to find out if this is a valid reason to return the films back to Amazon (had to order them there since they're not sold in Norway). If the NTSC films doesn't have these artifacts, I'd rather have them instead.

Rune, yeah, I consider the PAL versions a total fraud, I sent mine back to Lucasfilm, but I'd ask for a refund or a swap for the NTSC versions.
They are not a true PAL version as far as I am concerned.

Amazon has a 30 day return policy, and I'm taking advantage of it under the reason "quality of merchandise not as expected". I'll order the NTSC versions straight away and continue testing as soon as they arrive

And some shots of just the SE before and after:

There are, however, issues with this method. Because of the blue tint used, some blue detailing is "eaten" by the filter:

Notice the lighting of the echo base entrance and the core of chewies welder. Lukes lightsabre also suffers, but not so much that it`s noticable if you`re not deliberately looking for it. And only on the interior shots of the battle with Vader on Bespin. I suspect that might be more to do with Lowry`s algorythm than the histogram, since his lightsabre looks rubbish in the original SE on these frames as well. There`s also this:
Image7
For some reason the Lost in the Snow sequence suffers from a strange almost tourquoise glow that lessens or worsens depending on the scene. It begins with Luke leaving the ice cave, and ends at the cut to the speeders searching for Han and Luke. This`ll need to be manually corrected, but even this is proving difficult as i just can`t figure out how LucasFilm "colour corrected" it to mess it up so much. Certain scenes within this sequence (e.g Leia by the X-Wing, and the droids at the entrance), come out okay. Odd. But, for nearly all of the film this method has worked really well, and looks absolutely splendid. Yes, that`s the word. Splendid. I now just have to figure out what they`ve done to the lost in the snow sequence..

Do you need to select the area on the widescreen version, that matches the pan and scan version, so everything will be matched fine?

To be honest, i would`ve thought that the lost in the snow section would have benefited from readjusting the time compressed laserdisc version to match the SE more accurately, but it doesn`t. I am, however, currently making a new Pan And Scan version of the SE to write a new histogram and see if this helps, but to be honest that`s only because i have time on my hands. I`m not holding out much hope that it`ll work.

Originally posted by: Desree Oh, and this operation was performed in rgb colour space, as experimentation showed this to give a better match than either YV12 or Polar YV12. In fact, polar YV12 seems to do nothing at all, and is a waste of an afternoon of histogram rendering. Also, once colourlike was invoked, black and white levels needed to be corrected once more (i`d like to take this opportunity to thank the X0 boys for their tutorial on this), otherwise i got a washed out look:

Check that you are using the latest version of colourlike, the first release had the polar co-ordinates screwed up.
We do pretty much all colour correction in RGB colourspace whenever possible, it allows you to do corrections that you can't do in more limited colourspaces.
