StarWarsLegacy.com - The Official Thread
Time

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...

Harmy's STAR WARS Despecialized Edition HD - V2.7 - MKV (Released)
Time

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.

Color matching and prediction: color correction tool v1.3 released!
Time

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:

Here's a set of color corrections at 1080p. Some are pretty awesome, if I say so myself ;-):

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.

Here are corrections for three more bluray frames, including the notorious Mike Verta frame:

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

Star Wars GOUT in HD using super resolution algorithm (* unfinished project *)
Time

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 ;-).
