Here's super resolution v5. It maintains the enhanced detail of v4, while the noise compared to the source is significantly reduced. This is the best that I can do. Here are the same 8 screenshot comparisons:

Yes, the enhanced halo is unfortunately a side effect of the super resolution. I wrote my own super resolution algorithm in Avisynth based on the Infognition plugin. This algorithm dramatically enhances the detail compared to the standard super resolution. The halo is present in the source in most frames, so sadly the algorithm interprets it as cross frame detail, so it get's enhanced along with the rest. I implemented an advanced noise filter to counter the effects of noise enhancement. The halo however can't be deminished without compromising the detail and crispness of the upscale. To me it's an acceptable cost, but perhaps others will prefer the smoother alternative. 

Here's a first video sample of the super resolution v4. It's part of the Tantive IV scene.

@ Laserdisc Man

You accidentally compared your upscale to the Avisynth Spline64Resize, not to the super resolution v4. Here the correct comparison:

As before your upscale is cleaner with less noise, but mine contains more texture and detail. Interesting comparison!

@ Laserdisc Master

Could you show what your method would do with the soldiers face in the following screenshot I posted before for super resolution v4? I'm curious how it would handle the facial texture, and the lack of smooth shapes.

@ Dunedain

Thanks! I'm also quite surprised by the vibrant colours that come to the surface after the detail recovery and noise reduction, especially since I did nothing the explicitely alter the color palet of the source.

Here are three more screenshot comparisons for super resolution v4:

@ Zyrother

Thanks! I'm pretty happy with it. But part of the credit goes to Laserdisc Master, who continues to push the envelope with his incredible algorithms. 

Here are the first screenshots for super resolution v4. I'm rather proud of the result. It has enormous detail, but little noise or artifacts. I think it achieves a natural high definition look. What do you think?

These screenshots are all from the Tantive IV scene. I think you all would agree that was a pretty noisy scene. Here's what I've been able to do with it:

@ Laserdisc Master 

Wow, those look really good. Would be interesting to see a video. I've been working on super resolution v4. Screenshots coming up...

@ NeverarGreat

The complete movie is being processed as we speak. I decided to go for slightly less denoising. The Tantive IV scenes had very little noise compared to the source, but in close ups details like facial structure were somewhat smoothed away. It did look very clean though, so maybe some of you will prefer that version. The good thing about all the added detail, is that you still have a good amount of detail compared to a standard upscale even if you denoise rather strongly. So it doesn't have that cartoony look that many of the denoised GOUT upscales have. I will post comparisons for both versions later today.

Inspired by the discussion with RU.08 I decided try to reduce the noise. It appears that due to the high resolution of the upscale, much of the noise inherent to the upscaling method can relatively easily be removed using an advanced filter, without a significant detail reduction. Here are some comparisons between the noisy and denoised SRV3:

http://screenshotcomparison.com/comparison/122116

http://screenshotcomparison.com/comparison/122117

http://screenshotcomparison.com/comparison/122118

The noise is now generally less than for the Avisynth Spline64Resize and less than for the source material. 

Here's a denoised video sample:

https://drive.google.com/file/d/0B8_LYKyZDiajY1YwNGFHZmdEZUU/view?usp=sharing

The detail is retained, but the cost has been reduced. Thanks to RU.08 for keeping on the pressure. ;-)

@ RU.08

I understand, the problem is I don't find the loss of detail to be acceptable. You don't like the noise enhancement, that's fine. The price of reconstructing detail is that the "detail" in the noise is also enhanced (the haloing is actually part of the source, but is enhanced). However, the cost of your method is equally large, but you accept it, because it's part of the source. To me that's not good enough. The reference should be the high resolution source (in this case the print the GOUT is based on). The focus is put on undesired noise enhancement. However, to me what was lost in creating the GOUT dvd's is just as important. I've provided a way of regaining to a large extend what was lost, at what I think is an acceptable price. As I said, it's a matter of taste. Your upscale has less noise, but lacks detail. Mine has detail, but has noise. 

Star Wars SRV3 (crappy name I know, any suggestions?) will probably be finished by next week. I will make it available to anyone who's interested, but I've got little experience posting stuff on newsgroups and such, so some guidance would be much appreciated. 

@ RU.08

The last one looks much better indeed. Yours certainly looks cleaner with less artifacts. It certainly is a lot better than a simple Spline64Resize. Compared to my method, the downside is that there's much less detail. Personally I'm not a big fan of sacrificing detail to gain a smooth image, but that's just a matter of taste. 

My goal is to obtain a high resolution version of the GOUT, warts and all, so I've accepted that the final product will have excessive grain, and a number of other flaws inherent to the GOUT.

I'm aware that for many of you who are expecting a completely restored original trilogy, my grain filled high definition GOUT isn't good enough, but it's what I set out to do. As far as GOUT based upscales go, at least there's now another choice on the menu. Mine is a little rough around the edges, but I do believe it's the most detailed GOUT upscale to date, and I guess that may be of interest to some.

@ RU.08

A closer inspection of our methods also reveals a large amount of distortion in your upscale, compared to the Avisynth Spline64Resize. Just look at Vader's buttons. Apparently, the algorithm's desire to simultaneously sharpen edges, while smoothing noise, causes it to take liberties with the shapes in the image.

@ RU.08

Although your upscale is much smoother and certainly removes many of the artifacts in present in the source, it introduces an unrealistic smoothness to the frame. In that sense it literally is a smoothed and cleaned up low resolution image on steriods.  There is none of the detail or structure present that is native to high resolution images. In a sense you eliminate both the gain and the cost of my methodology, but essentially introduce a different cost. I guess it's a question of preference. Personally, I prefer mine (big surprise), but I can understand why you would prefer yours.  That's why I would indeed describe yours as a "proper" upscale, but mine as a "proper" high res reconstruction. 

However to get a better sense of the quality perception of the upscale/reconstruction, it would be interesting to see yours in motion and compare it to mine. I would say take the low res sample I put up and upscale it with your method for a proper comparison. 

Here is the first video sample of Star Wars SRV3:

It's not Harmy's Despecialized Edition, but considering it's based on a single low resolution source of rather poor quality, I think it looks pretty good. 

I stand corrected. I assumed there was a high definition master of the GOUT. So, I guess this is approximately what a high definition master would have looked like back in 1993. 

Yes, it does look like a film scan in bad need of cleaning, but I guess that's precisely what the state of the GOUT was back in 1993. These defects were not visible on Laserdisc, but certainly come out now.

However, this is not a restoration job. The task I set myself was to reconstruct the high definition master of the GOUT. This will of course not result in a perfect representation of the three films, but it is one way of obtaining a high definition version of the original trilogy. As far as I'm concerned that more or less what's been achieved (aside from some imperfections like aliasing). 

There are other people on this forum who are far more qualified to perform some sort of restoration. 

The post-processed Super Resolution GOUT Star Wars is finished. Here are the first screenshot comparisons. I have to say it looks amazing, aside from some aliasing issues present in the source material. I never expected it to look this good...

See the reconstructed detail in Vader's mask in the last comparison.

I guess I'm saying nothing new, when I say hooray to Harmy for giving us the despecialized editions of Star Wars. When I saw the trailer for this project on youtube, I thought it would be very interesting to see an actual "making of" documentary of the work that has been done and the different iterations over the years.

I'm kind of new to this forum, and catching up. Came across it when I discovered Harmy's despecialized editions. I just want to say I'm amazed by the amount of work (and years) that's gone into restoring these 35 mm prints. Great work fellas! As much as I love the work Harmy has done on combining elements from different sources to reconstruct the originals, it's equally wonderful to see the progress made at restoring the originals from an analogue source.  

@ Laserdisc Master

I would be very interested to see what MagicUpSR would do for the NTSC GOUT. Hope to get a sample to you soon. I was very surprised to see how much worse the PAL GOUT is compared to NTSC, despite the higher resolution of PAL.
