.: Citizen's NTSC DVD / PAL DVD / XviD project :. (Released)
Time
The French and German versions don't quite line up right. I think the French one is a few pixels left and one or two up from where the German one sits. The saturation's a bit different, too (the French is more saturated). Not too difficult to fix with AviSynth, but if you're just doing it for noise, I guess you'd have to consider the tradeoff against having to move stuff around.

Oh, and there are a few differences in the number of frames in each of the two versions. I think maybe one frame in ANH, a couple in RotJ, and I can't remember ESB. Again, easily fixed, but annoying to find.

<strong>The Cowclops Transfers (a.k.a. the PCM audio DVD's, Row47 set) Info and Feedback Thread</strong> (Released)
Time
Actually, MaximRecoil, my analogies (such as they are) do exactly what I hope they will do. In this case, they riled you up enough to actually provide good reasons to keep 'TR47' associated with the project. Well done!

I didn't actually ever mis-read your nick. My point was that your original reasons for hanging onto 'TR47' for a name were pretty weak and lazy. "It sounds good"? You sure didn't like it when I thought 'MaximumRecoil' "sounded good." "People are used to the name"? Also weak as hell. You didn't like me wanting to hang onto 'MaximumRecoil' just because that's what I was "used to".

Now, your new reasons? Worth paying attention to. Thanks for providing a cogent, concise argument. I'm serious. That's not sarcasm.

@ 88keyz: No shout-outs to me?? Ah, "the many more that I have forgotten or just don't know" -- there I am.

The first time I read your nick, I thought it was MaximumRecoil. I think everybody should call you MaximumRecoil, because for one it sounds good, and secondly, for the sake of continuity. I got it wrong the first time, but it's too difficult to get it right now because I'm lazy and don't want to make the effort to change.

Creating true &quot;black bars&quot;?
Time
I was quite confident you knew it wasn't from LD, but I did want to head off any enquiries from those maybe not quite so experienced.

The resource I always point to is Doom9.org. The forums there are where all the people who actually write apps like AviSynth hang out, so it's a rich treasure trove of all things digital video.

The steps you're probably going to need to take are:

1. Produce a D2V file from your DVD source, using DGIndex.
2. Write a quick AVS file for AviSynth, loading the D2V.
3. Cropping black bars is super-simple with AviSynth: Crop(0,100,0,100) should probably get you in the ballpark.
4. Adding true black bars is also super-simple with AviSynth: AddBorders(0,100,0,100) will be close.
5. MPEG-2 encoding is the trickiest part for me, since I've never gotten to that stage. But I know you'll want to use TMPGEnc or CCE to render it out, probably as elementary streams.
6. You'll need to re-author the DVD. DVDLab is a popular choice.

This is my official apology to Moth3r for being such a damn slacker when it comes to making comparison caps of both the NTSC and PAL discs on my D925. I swear it will happen! Just if you saw the rest of my "real life" schedule these days, you might see why it's taking a while. I've got at least one big other project to work on that shoves the comparisons down the list a bit.

That, and I'm lazy.

Smearing is a problem that is a bit tough to diagnose accurately. A number of average players smear otherwise-perfect CLV transfers. In other words, it's not always the disc; it's often the player. On the other hand, it is possible to do some video tweaking before mastering an LD, so some smearing can be the result of (especially) temporal smoothing.

So, to make the blanket claim that the DC is better than Faces because of smearing may be more a result of the player being used for the comparison than the actual quality of the transfer.

(For the record, I don't see any smearing on either Faces or the DC with my 925.)

So what you're saying is that you're not looking at the same posts as I am! Well, at least not the same meaning of "resizing" in those posts.

I totally agree that fitting the material into the "title safe" or "action safe" zones isn't the way to go. That problem of overscan/cropping is really only a factor on conventional CRT sets, isn't it? So the direction everything's heading (be it LCD, DLP, LCoS, plasma, etc.) should eventually obviate having to mess with the source in order to 'fake out' the display device.

As a bit of an aside, I went into my cheapo 27" TV's setup menu, and was able to get it to do the anamorphic squeeze trick. Sweet... However, apparently my model won't allow horizontal resizing the way it allows vertical resizing. Bummer. That means I'm still looking at a picture missing several percent of the left and right sides of the picture, due to overscan.

When I buy a projector, though, I'm anticipating none of this will be a problem...

Mavimao, are you reading the same posts I am? 'Cause I read Laserman to say that he will definitely be doing some anamorphic resize tests. Which I think is exactly the right thing to do.

To be perfectly bluntly honest, I think all you people who think letterbox-only (i.e. no resizing) is the way to go are on crack.

I still fail to understand how you can not see that having more of the frame available for the picture, and filling that up with carefully-crafted information derived from the raw data by someone looking at each scene and tweaking accordingly is preferable to having your TV scale it up like it scales everything else. I spend quite a lot of time on Doom9, where people are scaling up DVD to HD resolutions, and there is no question whatsoever that the end result is preferable to letting either your DVD player or your TV do the scaling. And these are people who capture anything and everything and convert to and from every format under the sun. There are guys there who know more about video than most of us will ever hope to know -- the sorts of hardcore video-processing nerds who can likely rattle off the mathematical relationship between YUY2 and RGB without consulting any references. I tell ya: if those guys figure upsampling in less-than-realtime beats the hell out of letting the player/TV do it, then I figure there's not much point in arguing.

Besides, pretty soon every DVD is going to be anamorphic (about 99% already are) -- so why would you want some oddball that isn't??

I would prefer a letterboxed set, becaue resizing lowers the picture quality, and the anamorphic version really has no benefit in the case of a laserdisc source.


<Before we derail this thread>



I was asking a specific question and not reopening an anamorphic vs letterboxed discussion.


Actually, you asked a specific question, and then went some way down the road to reopening the anamorphic vs letterboxed discussion by adding some editorial commentary, which was covered in the thread dumb_kid referred to.

With luck, one of the X0 Project team members will write a detailed anamorphic vs. letterboxed report for the website...?

Ah, but you never write "oo7," do you? When writing, you put "007." At least the makers of the films do, though even their scripts have people saying "double-oh seven."

I'm with iRantanplan: at least type "X0," even if you say "ex-oh."

Info Wanted: a question concerning a 1992 vhs boxset of the trilogy
Time
Not true. There were some anamorphic LDs manufactured in Japan that pre-dated DVD. Japan has had widescreen TVs (and HDTVs) readily available since the early- to mid-1990s, so it made sense to have anamorphic LDs in that market.

DVD definitely brought anamorphic presentation to the masses, though. Especially the laggardly North American market...

Don't get technical with me...

The best place to look for answers to both of your questions is at Doom9's forum: http://forum.doom9.org

You wouldn't walk into Blockbuster and ask about specs on a TV. Well, at least I wouldn't. People on Doom9 answered this sort of thing about four years ago. There's not much point in reinventing the wheel by hashing though it all again and again here.

What maybe should go here is some links to appropriate threads at Doom9. I'll see what I can do...

No. I'm pretty sure you can't. Unless you want to resample, but I thought the point was to capture what's there digitally, as bit-for-bit as possible.

LD AC-3 is 48kHz, BTW.

I suspect that would be about as accurate as Windows' copying progress bar! If my experience doing anything video is any guide, what you think is step 1 of 4 ends up being step 0.5 of 25, because step 2 ends up being, "Find out your first step 1 was a waste of time," and step 3 is, "Find out step 4 is actually step 18."

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

Weird. I know MBJ is referring to me when he asks about packet errors. I had a hell of a time with the AC-3 on RotJ when I capped it about three years ago -- it would always have about 1000 errors. Same thing when I tried my other copy, from the Japanese SE. Only that one side of one disc was messed up, but it was messed up on two different discs from two different pressing plants! I figured it was some sort of mastering error. (I mean, what would you conclude?)

Any chance you'd be willing to post your C program (compiled, I hope) and some brief instructions? I'm more than willing to do the work myself -- in fact, I've capped the AC-3 from that trilogy several times already, so I won't need much hand-holding -- but I don't know jack about how AC-3 is structured, and even less than jack about how to program up some C to deal with it. Can ya "teach a man to fish..."?
