"Real" is actually a loose term.... it just means meaningful data from your capture card, and not noise or interpolated data. And I totally agree that digital pixel to analogue comparison can be tricky (thats why I had the fudge factor 105%). But even so when digitizing an analogue signal you do reach a point when you're capturing noise rather than any meaningful data. This is heavily dependant on how clean you analogue source is (type of LD and LD player in our case) and capture device.

//Snip from videohelp:
Laserdisc resolution is 528 X 576/480, but many titles in US, after 1990, are using the 544 X 480 resolution.
In Europe, the success of Laserdisc was minimal, so the few released PAL titles, continue to use the official resolution for PAL (528 X 576). In theory, there is a 544 X 576, but I never saw a Pal laserdisc using this resolution.
//End snip

So I think at the resolution of your raw cpature you are introducing some interpolated and noisy data from your analogue source. Now this is good because you always want to oversample for any A/D conversion because you can filter out the data you want. Now what I'm doing is like you said, is some noise and interpolated data reduction by downsampling. When I upsample back, I believe I have more contol than your capture card via algorithm choice and configurabilty.

Did this in anyway help clarify and answer your questions from above?

I'll be honest I'm not a video capture expert, but I do have a pretty good background in electrical engineering and deal daily with various analogue sources that we have digitize to take readings from. But any A/D conversion is pretty much the same, its just how you process and display the data. For video its a time-dependant, color coded 2D matrix. Look out nerdspeak!

BTW I still can't wait to see your Empire and Jedi...keep up the awesome work

Cool thats what I thought...

I'm still playing around with your capture if you don't mind. Since the real resolution of PAL laserdiscs were/are 528 X 576 for 4:3, the real starting resolution of 16:9 slice you're using is 528 x 405. So what I plan on doing is first downsample your disc to 554 x 425 (which is just 105% * 528 x 405 to allow some fudging since it was analogue signal). Do just a little bit of noise reduction, etc and then upsample to 720 x 480 since I'm NTSC. From the samples I've done I think my 480 version looks just as detailed as your 576, but just a little more smoother and natural (no jaggies and less noise).

I got some flack from people when I said I was converting your disc from PAL to NTSC, becase I would loose "detail" since I was going from 720x576 to 720x480, but they failed to realize that we're starting from a source that has less resolution than either. If you go from 405->480 or 405->576 you're going get the same amount of real detail. The quality of the "added detail" from upscaling is dependent on your upscaling algorithms.

Moth3r,

At what resolution did you do your raw capture of the 4:3 letterboxed LD?

Yep... I remember a couple of christmas's ago me, my family, and my wife played the OT trivial pursuit. We decided all of them vs me... and keep in mind my family as a whole loves the OT and has seen it countless times. They got the first role and answered the first 5 or 6 questions in a row. Then I went and it was all over in three minutes. LOL

I fired up the old NPR radio drama from '77 and this what I found:

Luke: "What made the sand people leave?"
Obi: "I imitated the hunting cry of a krayt dragon, their imaginations did the rest and they took to their heels."

To-dah my useless vast knowledge of Star Wars trivia is correct!

straight from SW.com.... apperently thy didn't update their files after the DVD realese

Making the Jundland Wastes all the more dangerous are immense reptiles stalking the craggy canyons in search of prey. These huge predators are known as krayt dragons and their bone-chilling howl is enough to send even ferocious Sand People skittering for cover

I assumed that the lizard thing from Ep III is a Krayt Dragon. Even before I'd seen Ep III I'd decided not to change the sound in the DVD, and I'm glad I didn't because I like the link. The original noise sounded too similar to a Dewback, to me.

DE

The official name of the ep 3 lizard is a Boga... at least from what I could find online. When I first heard the new sound in a new hope I was like WTF is Obi making a crazy bird call for? It's not very scary to freak out the sand people. Just my .02$.

DE... I couldn't find anywhere in the discussion whether you fixed the noise Ben makes to scare off the sand people. The original version was a Krayt (sp?) dragon noise while the 2004 DVD is of the lizard thing from Ep 3.

I completely see where you coming from in terms lines of resolution PAL vs NTSC... but for me I compared the output from my XBox that plays the PAL version, my PC output, and that of the coversion I did for my NTSC Denon. To my eyes the Denon, with my conversion looks better for my particlar setup. Progressive scan vs hardware upscaling are two very different things. The raw PAL version when blown up(again this is for my setup) looked more noisy and had jaggy issues. The Forudja chip in my Denon really makes jaggies go away and also limits noise, even more so than my PC.... better algorithms I suppose. Overall it just made the viewing experience better for me. To each his own that's all.

Plus it seems silly for me to by extra hardware when I own software that can convert PAL to NTSC properly without any picture stuttering or sound issues...

OK we should be doen hijacking this thread... sorry.

I doubt those cheapo's have DVI output and a Faroudja chip to upsample to 720p or 1080i.

Now granted on normal 19" CRT TV any dvd player will do; my xbox can play PAL for my living room tv. But the above features really help out when you have a 10ft screen and a native 720p projector. I love my setup and it loves me

Unfotunately my good DVD player, a Denon 1910, can't play PAL discs, so I did a NTSC conversion over the weekend to see if I could. The conversion turned out pretty good... I'm going to do another one with some minor color tweaks and maybe some other tweaks that will be based solely on my own personal preferences. If they turn out well I may send a couple out to interested parties, that way everyone can share the joy of Moth3r's work.

That being said, I ran across a really cool PAL->NTSC conversion procedure that I'm dying to try out.

care to share a link to this procedure? I'd love to play Moth3r's transfer on my denon1910

I too am a long time lurker...

Moth3r hands down this is best LD transfer in the community yet. I watched it with a Sanyo Z2 projector at about a 10ft (3.3m since you're on the other side of the pond) diagonal. Everything held up nicely even at these large sizes. It was nice to see stars again in Star Wars. I really can't wait to see Empire and Jedi... and maybe versions 2.0 in the distant future. Your hard work is greatly appreciated.
