Denoise, Regrain And CC of ESB Grindhouse
Time

Guys it’s SO hard for me to spend more time on the Grindhouse given the glimpses I’ve seen of other potential sources coming on the horizon. The sad part is… I did a total cleaning of reel 4… and I can tell you with even with the rough grain intact (maybe BECAUSE it’s intact) it looks phenomenal (in my not so humble opinion, LOL).

However, when I started cleaning reel 1, that didn’t go as well for the intro crawl as I would have liked, and then I got pulled into the 4K77 project and that kept me busy for several months. Since then I’ve been focusing on losing weight and building strength up in the gym with some serious dieting so that I can be a healthier dad for my kids.

The original posts I made above promised something for Christmas at the end of the year, so let’s just see what happens between now and then. Worst case scenario I could release something incomplete that has 2 or 3 reels cleaned right? There’s a crowd here that would prefer grain and great colors, but with the caveat of dirt and scratches? But like I said… if TN1 and Poita perhaps join forces the Grindhouse print will seem like such a moot point.

I don’t know yet as I haven’t watched this print projected. LPP from 1983 tends to be grainier and lacking shadow detail, so hopefully this Eastman print will be much better, but I will know more once it has been cleaned and scanned, then I will risk projecting it.

The LPP was made a few years later, so may not be the same colour-wise as the 1980 release, but we will soon know for sure.

These are the frames I’m most curious about, can’t wait!

4k77 - shot by shot color grading
Time

Dr. Dre I love that you’re doing both the blu ray and 4K77 simultaneously in the same colors. There is kind of a crystal clarity to the blu ray in places… when you’re finished it might be fun to do a “Harmy style light” rendition mixing and matching the two to make something even more than the sum of its parts.

These are good times for fans of the original films are they not?? We’ve come a long way from having to upscale the GOUT DVD’s. 😃

4k77 released

The most amazing part of this post is that no two examples are even CLOSE to looking “similar” in color grading. But I definitely know which one is my favorite. 😃

To be able to compare 4k77 with other editions of Star Wars, I took the frame 5032 (GOUT-synced) of 13 versions: 4k77 (2160p), SilverScreen Edition 1.6 (1080p), BluRay (1080p), Despecialized Edition 2.7 (720p), GOUT DVD (720p), 16mm (480p), LD 1995, LD 1993, LD Mitsubishi, VCD, 8mm, HBO broadcast, VHS.

I adjusted the proportions of each version so that they fit and the comparison is visually effective.

In my opinion, the accuracy of the 4k77 version is similar to Blu-Ray. 4k is not really sharper than 2k (4k does not help much given the grain on the film).

This new 4k77 version has very natural and less aggressive colors than the BR or the DeEd 2.7, but the SiverScreen Edition(TN1) is still my favorite because it is less cropped and keeps the full width of the film (there is 11% more image than on the 4k77 version).

I’m really sorry Alex but I’m just not seeing any compression artifacts in that video. I see a ton of other issues, LOL… but not compression issues. ESB Dreamastered is denoised with non-matching grain on top. Whatever you’re seeing that is offputting probably has a lot more to do with the process than bit starvation.

A guy named Skydude has shown me it’s better to blend the denoised with the original, but of course that didn’t make sense here because the original is so trashed up.

Reel 4 cleaning is finished. I started with that one because I’m a big Yoda fan and it’s probably the easiest of the reels to clean. When the whole project is done I might do a raw “noisy” version and then another version with Skydude’s technique. For the noisy version a BD50 release would make more sense.

It’s funny this thread got resurrected as I’ve since learned how to manually clean the film… but the process is very time consuming… I keep asking myself if it’s worth two years of work, just to essentially get a noisy version of the film. But I’ve also seen another source for colors, and with two scene exceptions have luts that seem to work across a reel by reel basis, partially because I’ve also since learned to read and use lumetri scopes to color match.

I just don’t know.

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

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.
