Idea & Info: a different approach for restore bluray

the colors in the original trilogy bluray are very strange,in my opinion is happened an incorrect management of the icc profiles,than a color correction for fix the colors derivatives.I’ve tried a reverse operation for obtain the original data.In my eyes the result is very good for the quantity of detail in shadows, highlights and natural color.

I’ve created two luts to performing this operation automatically, one is standard ,the other one for the blue cast added in many scenes(everything is blue).

I think the only operation necessary are apply the lut,recover highlight and a soft unsharp mask.

Indeed after the lut i’ve noticed that most of the detail are in the highlights!!

some examples

And the luts (calibrated for the srgb colorspace)

my computer have too low power for editing a video bluray, so my request

is anyone is interested in this?

For the lut "look converter by picture instruments"(the trial version)...

i've saved the filter sample with srgb color space and open with a wide gamut profile....after this the color look more natural (this part was done with photoshop)

The other color correction in the screenshots is recover highlight and unsharp mask.

this is an example of uncorrected color profiles applied

I thought luts was that guy from 30 Rock, but now I see they are lookup tables.

These are all with the same correction? They look great! Keep going, age!

Yes pictures from first to Lando Calrissian have only one LUT apllied, the others have only the second Lut.

In the next screenshots first two picture have filtertemp lut applied,others have filterbluecast .

Some images are original compressed jpeg, final quality should be better.       The wall now is green but maybe is correct and the skintone are more pleasant imo.

Sorry for my english :-)

Pardon my ignorance here but what is LUT? and what software is doing this? your screens look pretty damn good! I could process the video, my machine is definitely strong enough.

A lut(look up tables) is like a preset but it's more fast, is used for calculate a color correction,change color space and it's very powerful.

For the software resolve lite, after affects , maybe avisynth with "rgb3dlut"filter....

 I'm pretty sure he just said it:

1.   Davinci Resolve Lite

2.   Adobe After Effects

3.   "Maybe"  Avisynth with "rgb3dlut" filter.....

Thanks, but I asked him which one he is using, I read that, I wondered which of the 3? but he PM'd me so now I know, so thank you.

For those who prefer watching the Blu-rays, this would be a life saver so the colors can finally look natural and not overly blue. Amazing stuff.

I have a full version of Davinci Resolve, if that'll help for this effort.

 yes for me that will help .Have you just tryied the luts?

I don't know how Davinci Resolve works.

For After Effects the first operation is load the lut under effect->Utility->Apply color lut

then  "shadows/highlights" for recover the highlights and a unsharp mask

Let me know your impression!

 Great question!

Is that guy...

This is really great. Thanks for sharing the lut.

I did a couple tests with Jedi (top is with the first LUT applied, bottom is bluray):

These are not messing with the highlights/shadow effect. 

The color look good.working space is to setting srgb, the default probably is rec709(hdtv) that is pretty similar but not the same.

test 3 and 4 are beatifull!!!

 I really like 3. That droid's head was almost solid blue before the adjustment.
