Only NTSC-m. NTSC-j is 0,0,0 / 255,255,255.

Heh, heh. I think I posted something to that effect just days ago. That's my North American bias showing.

255,255,255 roughly equates to IRE 109 from memory, and is clamped back to IRE100 in most broadcast systems. anything about 235 is considered 'Super White'.
We will be getting into a detailed article on what to do about the IRE7.5 vs IRE 0 situation, and what really happens and where (i.e. inside the various codecs and editing systems) as it is not always what you expect, and you can end up with video stepped up to IRE7.5 more than once resulting in an awful picture.)
Being a PAL man myself, my personal version will defiantely be in PAL, and we will have a whole discussion of the different systems down the track.

I think I'll be happy enough to read some progress is being made, whether it's linear and predictable or not!

Great to see you back here Laserman - and even more so that there will be a PAL version too

question is anyone working on custom covers for the XO editions???

I've started on one. Nothing to report right now though.
For those that keep asking what format these will be in and what versions, etc. The reason we haven't posted any definitive specs is because all four of us have different ideas in mind for what we'd like to have in the end. Expect at least a few different versions to come out of this project, except maybe a pan and scan I guess.

thats why you should own the vhs, for the preservation the higher the quality the better...

The NTSC image on that other thread is massively oversharpened. If it is a straight capture then either his LD player or his capture system has a nasty sharpening filter applying itself, you only have to zoom in on 3PO, or anywhere really to see the sharpening artifacts. This image is chock full of false detail. (So it looks sharper, but actually hold less 'real' information that the softer PAL image. Sharpen the PAL image to the same extent, and it looks more detailed)
This is contributing in a big way to the edge jaggies.
Just grab that image, and the 'soften tool' in photoshop (the water drop) and run it over the green grid, and suddenly it looks a lot like the PAL version.
If you get the jaggies, then use a vblur (vertical blur) filter along with a matte to fix the problem areas, and/or turn off all sharpening.
The X0 capture isn't nearly as jaggie, I had a look at home last night, I'll post an image once I free up some disc space. it definately looks a lot better out of the X0, but slightly jaggier than the PAL image on a raw capture (but a lot less noisy).
Having said that, NTSC always struggles with lines just off the horizontal in particular - especially in high contrast areas like this grid.
It is a combination of the lower resolution and the lower bandwidth of NTSC vs PAL.

I'd love to put a progress bar in place, but really you will have to read the articles and news, and make up your own mind how close to finished we are.
It is relatively early days yet, just marking up the timeline with any video errors, parts to recapture, gltiches to check (are they on the laserdisc or on the film or a problem with the capture etc.) means literally scrolling through the movie a frame at a time. A two hour movie has over one hundred and seventy thousand frames.
The problem with this project is that we want to get it right from the ground up, so a lot of time it means having to backtrack. Also, we want to document the whole process and share it with you all, so we are effectively doing a 'making of' at the same time. We spent most of the last few weeks writing articles, creating the images and so forth for that side of things.
The size of the files also makes it a lot of fun. By the time you have a lossless 80GB movie, and then six or seven versions of it on your drive because you want to check various issues, you end up having to constantly move things around, and nothing happens quickly because of the size of the files.
We have discovered more than I ever wanted t know about the nitty gritty of the various versions of the films - I've gotta say I was shocked by the colour cast issues on the official DVD, I wasn't expecting it to be quite so 'Revenge of the Smurf'.
SO where are we at?
Well, if this was a feature project, I'd say that we were in pre-production right now.

The quality difference is not all that great, part of the reason is that CLV is doing away with 'non-image' data, and so the reduction in space required on the disc, is not directly related to the quality reduction (i.e. taking up half the space does not equate to being half the quality).
CAV discs spin at a constant speed (RPM) , CLV changes the RPMs as the disc plays. On CAV discs you get one frame per rotation, on CLV discs between 1 and 3 frames (CAV is 1800RPM, which is 30 revs per second - NTSC is 30 fps, so that equates to 1 frame per revolution -that is why PAL and NTSC discs rotate at different speeds.PAL 25fps = 25 revs per second = 1500RPM)
CAV has a better average signal to noise ratio than CLV, around 2db better. CAV and CLV have the same SN ratio at the start of the disc, but CAV's s/n improves as you get towards the end of the disc where you get up to 2.6 times the amount of space for the pits and lands to take up.
Having to constantly change the RPMs on a big heavy disc is hard to do, so you do get TBC problems on CLV discs, especially if your player doesn't have a decent TBC built in. This manifests itself in colour problems and poor vertical edge stability. (Just like VHS - if you haven't got a TBC and you live in NTSC land, get one, you will be amazed how much better your VHS library will look.)
Other weirdnesses, errors on CAV encoded discs show up as a solid pixel or a horizontal line of pixels, CLV errors tend to have the pixels 'move' across the screen.
The main difference in consumer land is navigation - i.e. unless you have a LD player with a good digital frame store, you can't freeze frame or fast forward at multiple speeds, or jump to a frame etc.
In practice, on a good player, there is not a huge difference between CLV and CAV, often the transfer itself makes more of a difference, but with the same transfer, the CAV definately gives a better picture overall, but on some frames may be identical to the CLV version.

I'm not sure what is available at the budget end of the spectrum. I remember building one when I was a kid (though it was a line TBC, that newfangled frame stuff didn't exist then)
A lot of TBCs out there can mess with the video in different ways, so it pays to do your research and decide what features you want.
A TBC won't fix problems recording into the tape, but it really makes it a lot easier to get a rock solid capture every time.
I'd go over to doom9 or somewhere similar and ask guys what they are using and why.

Ooh, a laserdisc. The Cheat's playin' something on a laserdisc.
