Oh yeah, on compression we should be clear.
It was captured using the huffyUV codec, which is a lossless system.
That means there is not one single pixel changed from the captured image (unlike jpeg, MPEG, WMV. MP3 lossy codecs etc.)

So we are working in what most people would think of as 'uncompressed' video.
Huffy does compress the file sizes a bit, but does it just like a ZIP program does for zipfiles, it just stores them more efficiently without changing one atom of the original data.
Of course when they are posted here, we save them out as jpeg files which degrades the quality a little for your viewing pleasure, but not enough to worry about.

Feel free to post comparisons to the DVD here, I won't be posting them on x0project.com, but I don't mind them being compared.

Some shots are difficult to compare as they are totally different, other shots are untouched on the DVD except for colour and clarity, so they are well worth comparing. From memory on the latest shot, the starfield is completely different and CG.

I'm amazed when sometimes we get close to the DVD clarity wise, as the LD source is so sub par in resolution etc. , but we will always squeeze the best possible image out of every frame of that 80's invention (I still wish they stuck with the name 'Discovision' instead of laserdisc...pass the cheese)

We haven't even done the star processing routine on that shot yet, so expect a lot more stars to return to their former glory by the time we are done.

The new screenshot is really of an example of even when you are hard up against the limitations of laserdisc resolution, you can still make it noticably better.
For anyone that has an NSTC laserdisc player, you should find that screenshot looks *better* than it does on your laserdisc player - which is what we are aiming for - You get a better picture than if you went out and bought the laserdiscs and a good player.
Ya can't ask for more than that.

Well in a lot of cases your ISP will have it on their newsgroups if you are quick enough.
It is easy enough to do.

1) Download a newsgroup reader program
2) Put your ISPs news server in the address (or put in the adrress of your subscription news server)
3) Add the newsgroup (alt.binaries.starwars or whatever)
4) Tell it to get the current list of files.

If the files show up as complete you just tick them to download them. Because they are hosted on your ISP you get the full speed of your internet connection for the download.

Give it a try! You never know your ISPs newsgroup service might do the job, and it is free!

Well put, for the same reason we have used no noise reduction at all on our X0 captures or still images at this stage, we are still working out wether any noise filtering is a good idea, and at what levels.
It cracks me up to see some of the stills posted around the place that have had so much noise filtering done that it borders on posterisation, and I can only imagine that their final moving pictures would look weird and overly soft.

What encoder are you using cowclops to get it onto DVD?

BTW, I love your logo and its history!

Honestly, forget torrents and get into newsreaders. When was the last time all of your torrents came down at the full speed of your connection? Even on my crappy ADSL 1.5mbit link I average over 100Kilobytes per second for *every* download. Plus, you are not dependent on people 'staying on once they have finished' to get the download

Perhaps we should put a newsreader tutorial up somewhere if there isn't one already (I'm useless at searching)

Great link Karyudo, covers the vertical/horizontal issue as well, which I was not really clear on.
Another note, you never want to convert between DV PAL and DV NTSC without doing your homework, the standard method leaves you with 4:1:0 blecccch!

Edit:This might be why some DV projects in the US look awful by the time they make it onto a DVD - I'd never really thought about that aspect before, at least with PAL you would be staying in the 4:2:0 arena.

Re the stars on the NTSC/X0 version, we have been working on algorithms to process the stars in a better way, so no it doesn't suffer from missing stars like othe NTSC projects have, but it isn't anywhere near as easy to get them to appear as is is with the PAL version of the laserdiscs.
If we applied the same routines to a PAL capture they would probably massively increas it's starfields as well.

I think I spent around 200 quid on postage and customs duties alone last year, you are right Citizen and Karyudo, it is an expensive hobby - especially if you live in the Southern Hemisphere - We need some connecting tunnels to the countries where the laserdiscs are....

Big difference between both PAL DV and NTSC DV and PAL laserdisc and NTSC laserdisc when it comes to colour handling.

PAL DV is 4:2:0 whereas NTSC DV is 4:1:1, unless you use DVCPRO which uses 4:1:1 for both. D1 (or digital Betacam used in most TV studios etc.) uses 4:2:2 whereas the ATSC MPEG-2 standard for digital TV and HDTV uses 4:2:0.

So what does this mean? It means that NTSC DV and PAL DV handles colour (i.e. Chroma plus Luma) differently.
NTSC DV samples Chroma only once for every 4 luma samples. i.e. the horizontal chroma resolution is one quarter of the luma resolution.
The PAL system delivers a better colour result especially since it is coupled with the increase in resolution. It theory both NTSC and PAL DV end up with the same chroma bandwidth, but the different methodology gives a noticably different result.

We always remember who our friends are - thanks for the help.
I'm eagerly awaiting the new release of your cowclops sponsored effort, both to enjoy watching it and also it is great to have more sources to use as reference/comparison for our internal processes.

It can really help to look at how someone else has treated a particular scene, and to look for details and so forth in it that our processing may have accidentally screwed up or removed and so on. It is really exciting to see this scene humming again after a bit of a hiatus there for a while.
