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

DrDre said:

It isn’t really a problem, if you don’t use the algo to adjust colors you didn’t train it to in the first place. The algo shifts high/low saturation areas to how they appear in the reference frame. This is what it is designed to do. Artifacts are usually caused by extrapolation of the curves adjustment to colors it wasn’t properly trained to deal with. If you train the algorithm on those highlights, it will work just fine, and you have the smoothing option to further smooth the gradients where necessary. Like any method it takes experience to use it correctly. If you expect you can use it like some magic wand with zero effort, you’re going to run into trouble. I’ve rarely come across a source and reference that couldn’t be accurately matched with zero artifacts by carefully tuning the parameters.

I would advice everyone who experiences artifacts or other problems, to post the source and reference frames in this thread. I will then create a correction model, which will hopefully have none of these issues, and tell you exactly how I did it.

Interesting. I found I could kill 99% of the highlight glitches from the algorithm by putting a white block in both source and target images. I had reasoned that it was somehow overblowing out the highlights and clipping into black or something like that, so giving a white block let it know that in both images keep the whites white. (since white matches in both images, don’t let the correction exceed and clip) 😃

Neverar's A New Hope Technicolor Recreation <strong>(V1 Released!)</strong>
Time

I woke up with a startle at 5:30am. I got up and checked on my downloads. One piece left, 5 minutes left to go. 30 minutes later I’ve got everything assembled and copied to the right place. And then for the next hour and a half I enjoy this stunning work of art. Excellent attention to detail! Thank you again! And thank you for leaving in the Jabba scene! Though I own the blu ray I wouldn’t allow my kids to watch it… no need to hurt them with those terribad colors. Now I’ll let them see the new stuff too. 😃

oh man, that bluray looks so terrible, and your regrades so wonderful!

Just to nitpick, haven’t we clarified that the blu-ray always looks much more purple and terrible once the frames have been processed in any way? I mean, they still have crappy blue-ish grading, and Dre’s is a million times better. But it doesn’t look as bad as the frame grabs often suggest.

I forget who finally worked this out. Williarob or Neverar maybe? It unfortunately gives a little bit of credit to the pro-SE/PT trolls who have claimed, in the past, that our comparisons exaggerate the BD’s flaws.

Gonna test your theory and pop in the blu ray tonight on the plasma, and find this frame of Owen and see how it looks.

The Fox logo and title cards suffer from very low bitrate. It’s as low as 2Mbps at some moments, causing some macroblocking artifacts. The picture does get much much better, especially when it gets to Hoth. Is there a reason the video bitrate is much lower than version 1?

V2 has all the Despecialized audio tracks, plus fitted for a 25gb blu ray. So the video encode is quite a bit smaller than version 1. Side by side I didn’t notice much of a difference though.

Hey folks–hate to be a bother, but I am wondering if v2 has yet to have a public release! Went to the internal organ and had no luck finding it there. Please PM me if it’s available. Thanks in advance.

PM sent!

I already know how those posts turn out.

only if you have one of those fancy time machines with extra memory retention. otherwise you travel back in time, but don’t remember anything from the future. basically, time travel is real, we all already traveled back in time, that is why we are the only sentient beings around. but we all made a huge mistake and traveled economy - so no memory retention. we don’t even know that we are from the future.

OMG! **Spoiler alert: Most homeless people on the street are time travelers from the future. And the sad irony is, all of them went back and prevented major catastrophes before their memory faded.

I can remember back when you first started what a struggle this shot was. Thanks for sharing this journey with us Dr. Dre!

I’m seriously considering finishing this regrade, once project-X is done. Would there be an interest in yet another regrade?

On another note, the various technicolor print scans, and the frames themselves show slight, but consistent color imbalances between shots. Should these be kept for a regrade? What are your opinions on the subject?

My vote: FIX THEM, PLEASE. Especially for the blu ray release which is after all “modern special edition with extra graphix”. 😃 (I can handle the Episode 4 additions… at least it doesn’t have Vader going “NOOOOOO… NOOO!” D&SF(SD&(&(!)

Star Wars 1977 Technicolor IB print color references (matched to print)

The red pannels in the Death Star control room seem to be less orange than what we often see in other technicolor corrections.

Indeed, and considering the green shift in the print it’s even less orange when corrected.

It’s partially a saturation difference. Pulling those dark greens a bit and bumping the sat:
(I think this is a bit too hot, but just showing how the red panels change a lot)
