Wow! either that laser blast cooked his privates or his privates are a super-weapon.

Nice job by the way You_Too

The worst thing is that there is no selective color plugin for Avisynth, at least that I could find with a lot of googling.


*ahem* ;)

A selective colour filter for Avisynth

Any questions will have to be directed to the author, but by a strange coincidence he and I have never been seen in the same room at the same time...

(it doesn't do "Black", but I - I mean he - might get around to that sometime)

That's great! I can't understand why I could never find that plugin though. Anyway, I won't experiment with it yet, but maybe if "black" gets added sometime.

Here's a comparison of the current settings against Mike Verta's version, mine on top. (Hope I don't get banned for using this. I just had to show everyone)

That print has a very high contrast, and if I would push mine as high, some scenes would have clipped whites and an overall extremely bright picture. Just for fun though, I pushed up the white level of this shot in photoshop so you could compare it even better:

You_Too, that's quite impressive. Your colors seem spot on in that most recent photo.

If you are taking requests, here's one of those flash explosion shots which got cooked pretty good in 2004.  Might help figure out how far this orange and pink highlight shift goes.

Ouch, that looks bad. The 2004 seems to have a lot of flattened highlights like that. The blast frames are both too colorful and not bright enough...

You could use a little brighter image, colors are looking pretty good but otherwise the 2004 versions are too dark so they could use some changes in other settings too. Have you tried with the sequels yet?

Here's that shot and a couple more, blu-ray compared to my fixed version:

I've tried making the curve even brighter but in some scenes it ends up too bright, and will clip the whites. So to preserve as much detail as possible, I won't go any brighter than I already have.

I did try today with some shots from ESB, though I used the same settings as for SW just to check how it looked. (Since yesterday, I've changed the selective color settings for green and blue slightly. I'll update that on the first page when I'm sure it looks better this way.)

Should the same color curve can be applied to all the films? I know that the Hoth scenes in ESB had a blue cast even in the original version, but it was subtle, not overpowering like the '04.

From zombie's article on the GOUT color from his website, here's the first image from the GOUT with his custom color settings:

And the theatrical-print bootleg (which, as he points out, does have a pink shift):

You-Too,

I really think you're on to something here. I always suspeceted that there was an overall color change to the entire ANH, and maybe to all of the sequels, as the same color push seems to be everywhere. It's possible that individual shots were color re-timed as well, but I bet there are not very many, as that seems like a lot more work than what otherwise has been put into the DVD and BR releases.

I know you mentioned that you changed some greens and blues, so this may be resolved already, but the light green leaves in the back during the awards ceremony look too neon in your posted pics. I'd be curious to see what it looks like again with your new settings.

Please keep up this AWESOME work, and keep posting pics!

BTW, I have to agree with some here that the Technidisc transfer that mysycamore did is about the best color reference there is. Might want to do some comparisons with that.

I agree about the Technidisc. Also, I think the Moth3r widescreen bootleg is a pretty good source to use along with the Technidisc. It originates from a circa-'77 telecine of an original '77 print, and even with all the multi-gen detail loss and color signal degradation, it still has enough of the original color structure left in it to be useful.

I don't know if the same curve should be applied to all films, but I thought it was interesting to try! Haven't tried ROTJ yet though.

In that first pic of yours, look at the color of the ground at the bottom left. It looks kinda neutral compared to the blu-ray and my render. So maybe there should be different curves for each movie.

I saw that too, so that's one reason why I changed the settings. Comparison, old on top:

I think some of the Hoth scenes had their luminance levels totally f'ed with in the '04 transfer. Look at the Han/Leia corridor scene - I don't ever remember it being that bright, there were always dark shadows in that scene, and their faces were at least partially obscured.

Yeah, it seems that the same settings won't work. TESB is now way too yellow. So they need adjusting. :)

 I agree, same settings won't work, but each one of You-Too's ESB shots are better, and at least a step in the right direction.

The Technidisc does look good, but I think it has a little too much yellow/red in it?

Oh, I thought with "too neon" that you meant the greens were glowing too much. You mean they're supposed to be tinted more towards yellow? That technidisc version is oversaturated too.

The greens in SW seems to have a different look in different versions. On jedi1.com, negative1 posted some comparisons that had been posted here in the past. Since they've been on here, I guess it's ok to re-post a couple just for reference?

Anyway, notice how the greens are tinted more towards blue in the film print. I don't know much about film tech, so maybe it's because of fading over the years? Or did the greens look like that?

Ser mycket lovande ut, You_Too. ;)

I would not recommend my technisc transfer as some kind of reference, as already said, it's too yellow with bad contrast in many places.

The greens in Negative1's scans is definitely due to fading.

We want you to be aware that we have no plans—now or in the future—to restore the earlier versions.

Sometimes, but the color fluctuates quite a bit from frame to frame, it's hard to capture it in a still.

It is, but in a good way...it's got this very "old 70s Technicolor film" feel to it.

Maybe, but somehow I feel like the greens should be somewhere between that and GOUT. No way to know 100% sure, but I'm happy with my green setting as it is now.

Now here's a little surprise, I rendered a little clip in full HD of the Tantive corridor fight using my newest settings, which I've updated in post 3.

Here you go: http://www.multiupload.com/ONSHCE0WNE

The clip is compressed to ~24mbps (originally 36,8mbps) just to make the size a bit smaller, but I don't think it removed much detail.

Ok, after a lot of analyzing and trying different settings for selective color and curves, I'm starting to agree with some of you guys that it looked just slightly too yellow overall. Even if that looks good, it's not correct so I thought I'd give it a more advanced approach.

I took lots of raw screenshots from the blu-ray and put them all beside each other in one big lossless image. After that I applied selective color with some small new tweaks, and then I went to curves and let photoshop automatically find the "perfect" RGB values to correct the curves, and I then modified them using my overall gamma adjustment curve. I also made it slightly brighter without clipping any significant detail.

I'll show you the new version here, in a comparison to the old. (Old on top)
I think the difference shows the most in shot 4.

I was looking at that newest Tantive test. It looks better than the original timing, but the problem with a lot of the pink/orange flashes and stuff like that is that it looks like they actually dialed down the highlights (and pumped up the saturation?) on those specific parts of the frame. Whereas the GOUT has clipped whites, a lot of the flash frames and explosions in the '04/'11, have almost *no* whites. Areas of the blaster-impact explosions that were highlights in the older transfers look almost indistinguishable from midtones in the newer ones, and look almost too colorful in relation to the rest of the image.

I'm also thinking of things like the sleeve of the Jawa applying R2's restraining bolt - that amorphous purple blob looks to me like some kind of digital color grading matte. And Harmy just spotted the brightening of Vader's face mask in that one scene.

Looks like some crushed whites in the new ones.  Hmm, maybe the term is more properly "slightly blown".

I have tried to carefully push whites as high as possible without clipping, and I had to sacrifice just a very very little. I think it was worth it considering it looks like the bright parts are more "even" now.

Here's what photoshop reports as clipped. (Not the exact same frame but the same scene.)

http://img829.imageshack.us/img829/9226/unled1jm.th.png

I think me pushing the whites so close together creates an "illusion" of them being crushed more than they actually are.

Unfortunately, that's something that an overall setting for the whole movie can't fix, it seems. So I guess it's up to whoever is making a preservation to edit the explosions frame by frame.
