I'm curious, too... what I will need are two clips from the same shot, one from the MPEG2 BD, the other from UHE BD; 30sec clips will suffice, but they should be untouched, not re-encoded or recompressed.
It reminded me Aliens, too!
Yes, 8mm grain is DEFINITELY too much... I'm looking for 16mm grain, that should be in between them.
This is a test grain that should be in the middle (click for bigger version):
still need to test all these grain plates on video, rather than image.
Just to support "the grain theory" (like it, eh?) I regrained Predator UHE, and, despite the fact that obviously it couldn't make miracles, it works pretty well! Look at this post - and the following one.
I'd like to make a test using the clip for this shot: someone could provide it?
...or, with heavy 8mm grain (click for larger image):
Half way? WOOOW!!! You are so fast...

time to go to sleep now... 2:15 am here!
Thanks Sadako!
An .odt will be preferable, as I could edit it easily if needed.

I LOVE this kind of phrases! (^^,)
OK, here you are the test I made: took the worst offender screenshot from UHE, the same frame from the MPEG2, then I ColourMatch'ed the UHE with the MPEG2 as color reference, a blur, a grain plate and voilà: almost watchable wax face!

Sure think! Here you are:

contrast doesn't seem bad to me, but this grain plate definitely *seems* to improve perceived details... isn't true? Ah, how easy is to fool the brain...
Crazy proposal... IF the UHE could be considered "half good", it is possible to take the good scenes, add grain (from actual film, possibly from a stock similar to the original)to them, and use the other scenes from the old MPEG2... or it will be a total mess?!?
Konnichiwa! (with moshi-moshi, mirai, monogatari my japanese language knowledge stops here...)
Here you are the file, reuploaded: http://www.sendspace.com/file/5gb215 (1.3MB)
I think the best thing will be that Twister111 will continue his work up to image 20; Sadako will start from image 21; when ready, you should cross check your work, to see if something could be improved or corrected?
Is it good for you?
Please, just don't forget to menton image filename!
Sync'ing a laserdisc track perfectly with the BD video was a pain in the... you know what! (^^,)
But it's rewarding! DVD should be easier, though... I have never had a problem; when the DVD has missing frames - not many, let's say 2 or 3 - at reel changes, I simply add "null" frames with audio, and the soundtrack will stay in sync!
Still, nobody wrote anything about the test color grading I did... a simple "I hate it", or "I love it"... or also a "leave it alone" will be appreciated! (^^,)
I agree, and I repeat my thanks to Jetrell Fo, Doombot and CapableMetal, to have provided some Cinema DTS tracks for some of my projects; hope to be again your "client" for some of my future projects! (^^,)
Keep working on this, guys, it's an important task and I'm glad people like you are working on this great project...
BRAVI!!!
OK, grain 2 is good, and I don't know why I have NOT chosen it first... maybe because I used the old one thinking it was THIS one?!? (^^,) too many files, too many versions to remember...
What about contrast? Is bad, or quite good?
DoomBot, your "ticket for test clip" is still valid... write time, or name a scene, and I'll do another test clip with grain 2.
Test clip #2 with new grain 2:

contrast is a bit lower with grain plate applied, but not so much; waiting to know opinions.
Twister111, can Sadako give some help? I think so!
Domo arigato!

I don't really know much about PSNR vs. SSIM, but I would venture a guess that if these images were in motion, it would be much more difficult to tell the difference between the two compression levels?
You get the point!
As I watched and rewatched the test clips with added grain, I thought that this kind of grain plate is too subtle... I mean, grain should not be very noticeable, but only a bit; with the grain plate used until now, it was less than a bit...
So, I decided to test two new grain plates; they are similar, not very different when saw in static images, but quite noticeable in comparison to the old one; I must test them in motion!

opinions?
I decided to abandon the [ruLes] mark; any further laserdisc related project will be released under the [spoRv] "trademark".
Added some new titles to provisional list of future releases:
I'm thinking also about The Ring from D-Theater...
plus The Arrival (BD video with correct contrast & grain plate applied + LD soundtracks + LD extras) - to be announced soon.
Other ideas?
You have not to excuse: this is an hobby, not a work, and what you, I, all of us, is doing is volunteer and not paid so... don't worry!
And I understand you, as I have some health problems too lately - luckily not so bad; and I understand more the problems with pets - look at my new avatar!
I can't read japanese text in tumblr; probably is because I had to reinstall OS and forgot to install japanese language support... well, please make a reference for each image, using the original image title - like image 1 was season1_60626.JPG - it will be easier to me. OK for tumblr.
If I well understood, when there are only Google and/or Bing translation, then it could be (almost) exact, right?
Thanks again for your effort!
Test clip #1 ready (72MB, 20mbps, no sound):
http://www.sendspace.com/file/jrr7x8
I decided to do another one by myself; the shot at the beginning, when the scientist discover the flowers in the ice.
Test clip #2 (60MB, 20mbps, no sound):
May you pass your "test clip ticket" to another user? (^^,)
Thanks, I'll give it a try!
In ten minutes will be ready; problem, however, will be that uploading will take an hour or more... (^^,)
DoomBot?
