Well, now, that's interesting news. I think there's some room in my PM box for any information you might be able to send my way... please?

As for owning film, I'm just playing devil's advocate. I know of some friends with film, and I'm interested in getting a copy of whatever can be digitized, so I know how both sides of the argument feel.

A few comments:

1. I believe only PAL DV is 4:1:1. NTSC DV is 4:2:0. Or it's the other way around; I can never remember. But they're different.

2. Feature films are also often stored as log formats, so that there's more gradation in dark areas and less in light ones. Or it's the other way around; I can never remember. But it's not linear, anyway, like all the consumer YUV/RGB solutions we're using. Don't ask me to explain how that goes, exactly.

3. You can work in Photoshop in LAB colourspace, which is (I believe) almost identical to YUV. It's set up the same way, anyway: independent luma and two chroma channels. That lets you do stuff like blur stuff in one channel (let's say luma) without messing with the colour. Very handy for smoothing out skin, for example.

4. From what I understand, the gamut of YUV is smaller than that of RGB. Of course just how smooth and effective each colourspace is depends on sampling rates, etc., but in general RGB can display more colours than YUV (e.g. a whiter white, or pinker pink). Which I imagine is one of the reasons working in RGB is the default method for computers.

Let me ask a sort of oblique question: Do you think recording artists use 16-bit, 44100 Hz sampling when recording and mixing a song? No, of course not. It's best to leave the downsampling to the very last step. I think the same idea applies here. We're all trying to make silk purses out of sows' ears, and one of the best ways to ensure you're not losing any of the already-marginal quality available is to exceed the specs of the incoming signal. Oversample, if you will. Processing can take place in a format with more fidelity than what's available from the source or will be present in the output, which means you can fiddle with things without much fear that the output will have gone through yet another downgrade between capture and rendering. I think that's all that we're trying to do here.

re: Classic movie houses

I've looked into renting films, but all the lists I've ever looked at only ever have the SE versions for rent. You'd have to find some original film someplace else, I suspect. Which, as we've discussed, is pretty tricky.

re: University/College telecines

That's not a bad idea! Go to the places where Napster, KaZaa, BT, et al flourish, and the common currency is a case of beer -- brilliant!

I'd love to have a copy. I've got the 2004 DVD set (you want a UPC number as proof?). I've also got about 40 LDs -- that should make me pretty legal.

Be advised, though: if I get a copy, I'm not in a position to torrent, post, or make copies (sadly). So if someone else fits that bill better, send it to them.

If I still qualify, I can PM you shipping details...

I think the geographic centre of the X0 Project is about... Hawaii. So yeah, do it! I've never been to Hawaii...

It would be interesting to have an X0 release date on the same day as the Ep III DVD release, and then get all those reporters who found it newsworthy to interview people standing in line for the Ep III theatrical release to do a story on how grassroots support of a project preserving the original original trilogy is rivalling interest and buzz for Lucasfilm's latest.

If it were my money, I'd buy an X0 OT release before I bought Ep III on DVD.

If you make sure it gets to someone like The Dark One (aka Darth Osor), then it can be posted to Usenet and a whole pile of people can get it quickly and efficiently.

Not that I'm volunteering DO to do the posting; just that he's a previous example of a direct route to wide distribution via the best method.

Of course I'd like to get a copy, but I'm willing to spend the time and money to d/l it myself.

Well, it's not terrible, but you're not capturing the full colour values for each pixel. That's all. For doing all sorts of editing, etc., it's nice to have as much info to start with before "downgrading" to 4:2:0 for the DVD. DV is still pretty much the nicest consumer camcorder video format we've seen so far (HDV excepted...), so don't panic about all this esoteric, picky technical mumbo-jumbo.

Its colourspace and chroma subsampling. Not to mention MPEG artifacts...

NTSC DV is 4:2:0, which means one chroma channel is sampled at just half the resolution of the luma (i.e. 2 pixels share common colour info in this channel) and the other channel is sampled at half that of the first chroma channel (i.e. 4 pixels share common colour info in that channel). Compare with RGB—or even 4:4:4 planar formats—which stores 24 bits for each pixel.

Crop and Resize: prepare for / how to

Touche! (You'll have to imagine the e-acute)

The original poster (that's you, Arnie.d, right?) can almost certainly go back and edit the subject of the original post -- say, to something like "Best way to prepare to crop and resize?" -- if he wanted to...

A whole pile of this sort of info (i.e. pre-resizing, IVTC, pulldown, super-sampling, etc.) is covered in huge amounts of detail with giants in the field (i.e. the people actually writing the filters to do the stuff) on Doom9.org's forum. That's where I got most of my early info, and I've never seen anything better. Not to say people here don't know what they're doing -- they do, for the most part -- but asking here is sorta like asking about the ins and outs of the recording industry on a Grateful Dead bootleg trading forum.

And everything since, going into the details of pulldown, etc., has nothing to do with cropping and resizing. IVTC is a necessary first step, true, but a full-on, dragged-out, step-by-step description of how to add pulldown with Pulldown.exe is not "best way to crop and resize."

Unless you'd agree that a full-on, dragged-out, step-by-step description of how to install drywall (including the finer points of drywall screws) belongs under the heading "best way to paint your living room."

I don't really mind—like MBJ, I'm enjoying the nostalgia of it all. But it still ain't "best way to crop and resize."

PAL vs NTSC laserdiscs

I'm pretty sure all PAL LDs are CAV, actually! Don't forget that PAL needs only 83% of the frames NTSC does to show film material. The German discs are indeed CAV, anyway.

I still think CAV is highly overrated, except for freeze-frame on mid-range LD players. For capturing, there's really no difference at all between CLV and CAV. It's just how the signal is laid out, not that the signal is any better.

If you've made a PAL cap at 720 x 576, and you just want to keep the middle 480 lines for NTSC, the aspect ratio will be wrong. Call me stupid, but I don't understand how you can "not use the full width" of 16:9 without scaling the picture. I'm willing to be proven wrong, but the three seconds of thought I've given this suggest I'm not.

Non-ana 2.35:1 PAL is about 330 lines; ana NTSC 2.35:1 is about 360. So if you scale up just 10% vertically, you'll be right on the money in terms of aspect ratio, with a very small amount of scaling.

I'd also take issue with the claim that "it makes a big difference" to the image quality by not scaling. I think Moth3r's captures (which you've all seen) and my own (which you haven't) refute that pretty solidly.
