Too much Noise Reduction

I did this in about 30 seconds.  Just took a raw frame, applied a standard but robust de-graining algorithm, and added grain back.  Looks a lot like Lowry to me.  I'm sticking with this theory because if nothing else, it is 100% certain that noise reduction was used on every shot.  But whatever... however it happened, it happened, and is just 1 of a billion travesties in the results.

I'm just interested as to wether it would even be possible to maintain that detail on a BD release no matter what you did, if you want to leave the gate-weave in.

I tried it, and it smears out, just like the BD release.

I don't think it would be possible to keep that detail, and the gate-weave, due to the resolution and compression on a standard Bluray.

BD is still quite limiting with the resolution being relatively low for cinemascope movies, and the compression method (H.264 is pretty damn lossy, and over 10 years old now) results in a lot of detail being lost. Not all of the woes on the BD are due to the methodology used in the reconstruction of the film, or at least, in some cases, like this one, it would make no difference in the end result as it would happen in the encode anyway. e.g. the missing detail in the door seal, some of the macroblocking on the red lights, the burned out highlights mentioned also appear to be burned out on your scan as well etc.

That isn't to say that the Lowry noise-reduction didn't wipe the detail before the encode, but even if they hadn't, I can't see some that detail making onto a BD release. I guess I'm just trying to point out that some of the problems with the BD release are inherent in the medium. Of course a lot of other problems with it are just poor choices, or choices due to economic realities when working on a commercial release. As fans we can take as long as we like, at a company as you have said before, it is a very different story, especially if you know that the final product is a BD and know that format's limitations.

I'm glad you are doing this at 4K and keeping a losslessly compressed master, as a lot of the restoration work would be lost anyway if made into a BD.

Nice stuff.

Looking at the frame though, the detail lost in the door trim might not have anything to do with Lowry.

Measuring that door frame @ 1080P there are very few pixels available to convey the detail (4x less than at 4K), and when you factor in dropping to Bluray standards (8bpp and 4:2:0 chroma compression and h.264 compression) this is exactly the sort of detail that would get smeared out by the lower resolution and BD compression rates.

Not defending Lowry et al. but the loss of that detail could just be down to the limits of BD especially if there is gate-weave giving the compression algorithm headaches.

It would be an interesting experiment to take 20 frames of that sequence from your scan, and compress it to BD specs and see what is lost even in the most careful conversion possible.

What does OUT stand for? Old and unaltered trilogy?

OUT

Original Unaltered Trilogy, usually refers to the original 35mm theatrical  releases.

GOUT.

George's Original Unaltered Trilogy (as coined by Laserman), usually refers to the crappy DVD release that used the old LD master tapes.

 Yes, that is an insanely huge download. Most wont be able to manage it accept for those who have the fastest speeds. Wouldn't it be better to compress the uncompressed file to a BD-50 size file so that sharing it would be much, much easier to manage.

 But sharing it for what purpose? If it is just to get a sticky-beak, or see if any frames are missing etc. then perhaps a divx 720P version or something would be more worthwhile.

A BD-50 of an uncorrected scan doesn't serve any purpose, it would still be a big download, but basically useless as a starting point for restoration/preservation.

 It is losslessly compressed, a little higher than 1080P from memory.

As is hasn't been colour corrected yet, and is high bit depth, linear colour-space sharing heavily recompressed versions would be a bit pointless, as you wouldn't be able to properly correct from a lossy, 8bit version, and there isn't a lot of point having the files to work on, if you throw away all that detail before you begin.

Is that the same frame with the missing pixie dust?  Because that looks great.

Edit: No it is a frame early but it looks like it has the same amount of pixie dust as the laserdisc, just with more detail, dirt and better colors: http://originaltrilogy.com/forum/topic.cfm/Recommended-Editions-of-Disney-Animated-and-Partially-Animated-Features/post/653541/#TopicPost653541

Looks

 I think this is the correct frame.

A 3D HSBS question
Time

On your computer, you will need a 3D monitor, or run it to a 3D TV.

You will need to use the active glasses that came with your TV.

The easiest way is to plug the computer into your Sony 3D TV.

Just use VLC to play it full-screen on your TV, go into the TV 3D Options menu by using the TV Remote, and choose 'Side by Side' as the 3D type.

Put on your 3D Glasses and enjoy the movie.

trying to figure out what i have 1983 701 final cut of star wars
Time

asemechanic76 said:

its all the cut outs (edits) of the original star wars just found out

 Well, 1983 would most likely be the Reagan Star Wars initiative.

Whether it is Lucas' Star Wars, or Reagan's Star Wars, it is still of interest.

I am happy to scan the footage for you free of charge, which would likely increase its value as you could offer a digital copy of it along with the film. Whereabouts in the world are you?

The files are in high bit-depth .exr format, so if anyone wants to view them I would recommend downloading the free version of Davinci Resolve, or the trial version/PLE version of Nuke

Davinci MAC

http://www.blackmagicdesign.com/au/support/detail?sid=3948&pid=11735&os=mac

Davinci Windows

http://www.blackmagicdesign.com/au/support/detail?sid=3948&pid=11735&os=win

Nuke

http://www.thefoundry.co.uk/products/nuke-product-family/nuke/trial/

Both are multi-platform (OSX, Linux, Windows) and support the OpenEXR format correctly.

kk650's Star Wars Saga: Regraded and Semi-Specialized (Released)

kk650, one thing you'll want to be careful of is some purple making its way into certain shadow details. The shot of Uncle Owen at the sandcrawler exemplifies that a bit. I know You_Too did an avisynth script to get rid of it back in the day. I'd check his color correction thread for more info on that one. Not sure how you may be able to address with what tools you're using.

 I'd really look into Davinci Resolve, it is free and lets you make the colour changes you require without causing problems in the other areas.

Well worth learning and there are tons of online training resources.
