@snicker: I never touched that shot and the gate weave of the stars tells me that it wasn't digitally recomped either, so I assume it was always that way.
I was referring to the Blu-ray and not your edit mate. Just wanted to point it out as I can't recall it being mentioned previously.
Harmy, I found something interesting while doing some editing. In the DS hangar behind the Falcon you can see a join in the starfield where two backdrops marry up. I don't think it's a fix just something I've never seen mentioned before. Sorry I can't remember the frame number as I'm at work but it's the eye level shot where Vader and the Imperial officer walk into frame and approach the Falcon.

I wonder if those fixes would work for ESB and ROTJ?
Can't see any reason why they wouldn't. Is clipping a problem with either of those transfers? I'm really only familiar with Star Wars.
Harmy said:
Yeah, not worth it. I'm not even working with the raw blu-ray, I'm working with You_Too's over-all colour fix rendered at 720p.
I figured it might be a bit late to incorporate, just wish I'd figured all this out a little earlier. Anyway, I'm liking the look of your latest workprints a lot. Good luck with the rest of it.
Harmy said:
Yeah, I see what you mean snicker but you didn't explain how you did that, is it complicated?
I guess the main complication for you at this stage is that the settings have to be applied to the raw Blu-ray capture. I don't know if you have it split into separate sequences for editing but if so it would be impossible to apply now. The only way to do it would be to render the whole movie with your settings in lossless, load it into After Effects, then apply the red fix as a colour key, tune the colour to match your render, and re-render. Pretty painful.
I've been working with individual colour channels to build up detail in each one. The red channel highlights clip a lot, the blue channel too but not quite so much and the green channel rarely clips. It's not often that you have clipping in all three channels simultaneously so there is usually good detail in at least one channel. The green channel is often useless because the white point is so much lower than the other channels but it can be used as a 'base' to restore some detail in combination with the blue channel which contains most of the highlight detail.
I've used 4 keys just in the red channel alone to build up the red highlight detail as well as using difference mattes to limit the areas which are being altered.
So basically I started with three precomps - one each for the red, green and blue channels, worked on building the detail in each using colour and luma keys, then used 'set channels' in a fourth precomp to set each of them as new R/G/B channels. This then becomes your new video layer.
The top image here shows the result of clipping in the red channel. This problem presents throughout the movie and is responsible for a loss of detail in explosions and also why a lot of the laser cores are missing. Together with a (sometimes) badly damaged and clipped blue channel it also contributes to the bright magenta in a lot of shots.

Hopefully this illustrates what I'm talking about a little better.
It would be more helpful to compare against still from the workprint. We already know the Blu Ray colors are wrong, and Harmy's workprint doesn't look much like the Blu Rays anymore. Are you sure there's even a problem to fix anymore?
The issue I'm trying to point out is with the red channel highlights clipping so that any bright red object becomes an area of 100% saturation/brightness and the image detail is lost. It is possible to restore that lost detail with good information from the other colour channels as shown above. Harmy's colours are not the issue, they're actually great. I personally find that these clipped reds stick out like dog's balls so if it's something that bothers him, and he's interested in fixing them, he can.

Not to offend here Snicker but i prefer Harmy's colors, that wall you are talking of seems to lose detail in your shots and C3PO looks to dull, i guess it all comes down to personal opinion, and since Harmy is basing his colors from a very decent source i think we must trust his judgement.
Hopefully this illustrates what I'm talking about a little better.
Images 1 and 3 are untouched Blu-ray grabs and 2 and 4 have been corrected to eliminate red channel clipping in the highlights visible in the red flare on Artoo's dome and the red light on the wall behind Threepio.
Cheers for that.
Harmy, I've uploaded my images to ImageShack but I'm unfamiliar with posting images in forums. Do I need to resize from 1280 x 1091 and if so how do I do that while linking to the original larger image?
By the way, it's not to point out colour issues as such but rather a fix for clipped red channel highlights which is one of the biggest issues with this transfer.
Harmy, I have a suggestion regarding colour and need to upload a couple of images from my harddrive. Could someone please tell me how to do that?

You-Too, would you be OK with me posting some comparisons here of my own corrections or would you prefer I start another thread?
If you're using my settings you could post some, as long as you apply selective color before the curves, and keep it like that. If you're making completely own corrections with own settings you should make a new thread.
I'll make a new thread.

Thanks for all your hard work on this project, Harmy. Amazing. Could I have the links please?
