Great! Keep 'em comin'!
Great! Keep 'em comin'!
As some of you have noted, there is a French article about Legacy:
http://www.hdnumerique.com/actualite/articles/14774-star-wars-un-nouvel-espoir-la-version-non-retouchee-restauree-en-4k.html
They were probably inspired by a thread I started on theforce.net, since they used one of the color corrected frames I posted there. Anyway, if your interested, you can check out the thread:
http://boards.theforce.net/threads/star-wars-legacy-edition-restoration-of-the-1977-original-star-wars.50032868/
Mike has also posted there, and had some interesting discussions with theforce.net members, many who support him, but there are of course also the SE crowd who will defend George Lucas till their last breath...
What's interesting is that they used one of my color corrected frames of the bluray as "the original". They probably assumed it was from Legacy. I started a thread on theforce.net about Legacy. It's been one of the more popular threads, and Mike himself also posted there, to explain about Legacy. I also posted some of my corrections there to show how bad the colors of the bluray are.
Just for comparison, this is what you get by directly correcting the last frame with histogram matching. It is much worse than the prediction, based on another reference frame, and unable to correct the blue color of R2's panels:
I finally managed to extend the rotations method to be able to predict different frames. Most of the color corrections shown are based on a very similar reference. However, I believed that it should be possible to use the color correction model calibrated on one frame, to predict the color correction for frames in the same scene, as these have usually been altered in a similar way or have faded in a similar way. I tested my method on the bluray/digital download, and this is what I get.
First I calibrated the model on a 720p frame:

Then I predicted the correction for this 720p frame:
http://screenshotcomparison.com/comparison/140782
The results of the prediction are:
http://screenshotcomparison.com/comparison/141323
The prediction is a bit brighter, but it is very close.
Next I calibrated the model on another 720p frame:
http://screenshotcomparison.com/comparison/140902
Then I predicted the correction for this 1080p frame:
http://screenshotcomparison.com/comparison/141262
The results of the prediction are:
http://screenshotcomparison.com/comparison/141324
The prediction is a bit darker, but it is again very close.
So, to summarize, here are the color corrections, based on a color correction model calibrated on a different frame:
Or if anybody prefers any of the other color gradings from the GOUT, JSC, 97 SE, and 2004 DVD, based on Althor's compilation:
We aim to please:
In principle it is possible to retrieve the colors with a color matching algorithm, provided you have a good reference. In this case I matched the colors of the print to the frame posted previously from the Semi-Specialised Edition V2.2 (bottom):
Here's a set of color corrections at 1080p. Some are pretty awesome, if I say so myself ;-):

In a few days there will be another video sample for SRV14. I've found to enhance the detail, while keeping the grain reduction.
Ps. Haven't had time to clean up the scripts for SRV12 & SRV13, but those will be posted in the next days also.
Here's a video sample for SRV13:
https://drive.google.com/file/d/0B8_LYKyZDiajRlpJeHdldVh5ejA/view?usp=sharing
SRV13 is softer than SRV12, but does not have the pervasive static grain.
The strange orange blotches in the Alderaan astroids/tie fighter chase scene in Harmy's Despecialized Edition appear to be mostly the result of the color correction, and not a makeup issue or color timing issue of the bluray itself:
The video sample is done. I just have to add sound to it, and convert it to mkv, so it should be online this evening (European time).
The model I use automatically adjusts the saturation, tint, contrast, and brightness by estimating how the three color channels in multiple color spaces have shifted. If the original frame has a lot of contrast, it can become darker, and if it has a lot of highlights, it can become brighter.
One thing I noticed is, how much depth is added to the frames. The bluray colors are really flat.
It's also amazing how screwed up R2's blue panels look in the bluray. In that last frame Han's pants are also far more blue, than they were originally. Here's a prime example of how screwed up R2's colors are in the bluray. In this frame he simply looks awful in the bluray:
Three more great shots from Star Wars color corrected:

I haven't followed the thread, but in principle faded colors are not an issue, if the scan has enough color depth. You would need some color references, preferably as many as possible, for the best results. The reference can have a SD resolution.
Here are three more corrections to the bluray. The difference for the first frame is huge:

Here are corrections for three more bluray frames, including the notorious Mike Verta frame:
http://screenshotcomparison.com/comparison/140675
http://screenshotcomparison.com/comparison/140677
http://screenshotcomparison.com/comparison/140679
There are still a few pink highlights in the last frame, but it's much closer to the original colors, and perhaps a few more interations will get rid of those highlights.
Here are some improved color corrections:

Here are a few preliminary bluray color corrections. The crushed blacks of the bluray are an issue, but you get the idea:

Glad to here you're still here, Poita! Those scans look great! Good colors too!
Yes, I'll clean up the script and post it along with the sample.
Another video sample will be ready in three days. I believe I've managed to get rid of the intrusive grain, but at a price of course. However, I believe it can be best judged in motion. I will post a sample for both SRV12 and SRV13 based on towne32's cleaned up GOUT, and then it's time for critique ;-).
Possibly, I will do some tests first to see how it works out.
