@ Laserdisc Master
I just noticed some pretty bad artifacts in one of the frames of v7, so I'm inclined to agree with you. So, it's back to v6.

I don't suppose you would consider using your methods on the two trailers for the Force Awakens? I've downloaded them from youtube but would love copies of them in better quality. You can download them in 1080p but they look quite soft.

I will give it a try. Since they are 1080p I'll have to upscale to 4K and then downscale to 1080p and see if the quality improves.

YouTube HD is terrible. Highly compressed to save space and bandwidth. Only 1440P and higher is of acceptable quality.
You can see if the Star Wars website has a different copy, but I assume all will be 1080P. Plus, the film itself may have a very soft focus on it, or the trailer was supposed to be presented that way. With digital films, the quality is never that good.

Isn't TFA shot on 35mm film?

Oh wow, you are right, It is being shot in mostly 35mm, with some 65mm IMAX segments. That's ultra cool. Gives me some hope for the film then. I haven't watched the trailers, so I simply assumed it was digital. Sorry about that.
So then I assume its YouTubes crappy handling of HD videos.

Ok, so I don't have a perfect working knowledge of super-resolution, but my understanding is it needs two pictures to work and you are using neighboring frames to accomplish this, correct?
My question is, why not use two different souces, such as the GOUT and another laserdisc release and do this using two of the same frames from either source to accomplish the super-resolution process, thus eliminating some of the issues that may come with using neighboring frames?
Here's a comparison of the various Laserdisc projects: http://www.aptirrelevance.com/otscreenshots/screenshots.php
Each one seems to have slightly different cropping, so you may need image registration software to do this, but none of the laserdisc releases seem to have any of the 'haloing' artifacts of the GOUT (seen around 3PO's shoulders for example).
You probably don’t recognize me because of the red arm.

Which Laserdisc set is better? The 1993 set, or the 1995 THX ones? I heard the 95 ones are merely the 93 discs in different packaging. But I also heard they did some minor improvements as with the 95 'Faces' VHS set. Cant verify which is true.
I would assume a new digital rip from one of those sets would give more flexibility.

From my own post (found here):
- DVNR-free + no white clipping - NTSC Japan Special Collection, NTSC US Special Widescreen Edition, PAL french "pyramid" boxset, PAL german Silver Screen edition (some with the "incredible shrinking ratio" problem)
- Light DVNR + white clipping - PAL french THX subtitles, PAL french THX dubbed, PAL german THX, PAL spanish THX
- Strong DVNR + white clipping - NTSC US and Japan Definitive Collection, NTSC US "faces", NTSC Japan Collector's Set - also GOUT PAL and NTSC DVDs of course...

As all of you know the picture quality in the GOUT is variable, so for the master of Star Wars SRE (Super Resolution Edition ;-)), I decided to use variable filter settings for some scenes, to make the movie picture quality more consistent. The scenes where the stormtroopers enter Tantive IV required special attention. Here's what it will look like:

@ Laserdisc Master
Wow, those original ones from 1989 are the best ones, even though they have that ridiculous shrinking aspect ratio? Never would have guessed....
Definitely going to stay far away from those 95 and 93 Laserdisc sets then.
Thanks for the information!

DrDre, that looks a bit too smooth for my eyes. For example the "corners" of the pillar in the first screenshot. And there is this weird pattern over all the walls that looks like the white is painted on with a brush.
Darth Id on ‘Why “Ben”?’:
And while we’re at it, we need to figure out why they kept calling Mark Hamill’s character “Luke Skywalker,” since it’s my subjective opinion that his name is actually Schnarzle Shnuzzle. It just doesn’t make sense!
Damn you George Lucas for never explaining why they all keep calling Schnarzle “Luke”!
Damn You!!!

I may have overdone the smoothing a bit. This one is better:

It seems it would be tough to remove only the noise, yet leave the natural grain structure. Scrubbing away every single bit would leave a very smooth, and waxy image. No good.
So far, the increase in detail is staggering, even if some of the natural grain is being removed.

I think you are right. Trying to remove too much noise, generally washes away the detail, and gives the frames a painted look.

Great work DrDre. I check in on here every once in awhile to see what the fans are up to and I'm always impressed with what I find!

Well, it took some work, but here's super resolution v7. Using a more advanced filter, I've been able to further reduce the grain significantly, while maintaining the detail. Here are the first 4 screenshots. The last is an example of a difficult frame with much grain.

It's interesting to see that the detail enhancement and noise reduction also restores the color to a certain extend.

It appears that the sheer amount of noise and grain actually diluted the color. That is fascinating, I have never seen that before.

A very nice improvement in detail with this method. :)

Considering the capabilities of what may now be called the restoration engine of super resolution v7, I thought I would push the boundaries even further. In these examples two of the worst examples of GOUT frames with incredible amounts of grain are completely restored:
