Doctor Who

Not going to spoil the plot but the first episode of the new look series was fun but spoiled by some 1990's style CGI and the worst rendition of the theme tune since the Sylvester McCoy era (only the hideous Delaware version trumps it and they ditched that after one episode).

Haha, the "McCoy" era was the end of the "classic series" unless you count the movie. The new theme isn't great, but it's better than McCoy's theme! The new theme sucks, the new logo sucks, the new tardis sucks, the new companion sucks and the new doctor sucks. I disagree about the CGI though - it should be MORE cheesy after all that's what Dr Who is all about! They should make an episode "the four doctors" out of the four doctors since the end of the classic era.

Star Wars OT & 1997 Special Edition - Various Projects Info (Released)

"crappy gout audio"! Digital audio versus digital audio. What did you want? A PCM track? The Laserdiscs had a 16 bit 44.1 kHz soundtrack. D-3 Tape (which is in all likeliness the probable format of the masters) holds audio 16 to 20bit at 48kHz. DVD Video DD standard is 48kHz. You tell me which is the "crappy" audio. "But it's a Dolby Prologic track" - that doesn't matter. Dolby Prologic was designed on and for analogue audio, compression doesn't matter.

Look at it this way: 1. DD AC3 Track @ 192kbps, 2. PCM @ 1.5Mbps.

That's 1.7Mbps. The maximum DVD bitrate is 9.8 Mb/s, therefore your new maximum video bitrate is 7.9Mbps. Yes, strictly speaking it should be 8.1 on a purely mathematical basis, but this is the real world. On the other hand no PCM audio and you can safely set the video's maximum bitrate to 9.4Mbps.

Could an analog optical disc format be made today which could equal or exceed the quality of a 35mm film print?
Time

Using something like Blu-ray discs, and an analog scheme like LaserDisc (but with something better than the composite domain, such as RGB) — if transferred from a 35mm negative, or better yet, a 70mm negative — could the quality of a 35mm film print be matched or bettered?

Something like that combined with a high-end CRT projector (to keep it all analog) like a Sony G90 with a 150 kHz scan rate (well beyond 1080p) would allow commercial theater quality and the look of film right at home, without the hassles (such as switching reels), huge expense, and potential legal red tape of owning actual 35mm film prints. 

It is too bad that some of the best CRT projectors can handle well beyond 1080p, yet the highest quality consumer analog format that can be fed to them is something like LaserDisc or S-VHS. Yes, they display digital 1080p content, but media that's high resolution and completely analog would be really cool. It would probably be indistinguishable from a film print when viewed on an analog display.
Okay, here's the problem. Most 35mm films only have around 2k discernible detail on them. Digital is the future, because the film can be made to look the way it was supposed to look - richer blacks, whither whites, full balanced colour, etc. Others disagree and I can see that, fact is that digital can reproduce everything on the film AND remove the negative effects of film. If you don't believe me, see if a 16mm film version of your favourite movie looks better than the DVD.

Of course the tweaking is done (preferably) at the saning stage, because in the digital stage your loosing colour fidelity. I doubt you'd notice the difference in most instances between 2k and 4k. And 1080p just about captures 2k as it is. That said, there are certainly movies with the detail to go to and beyond 4k in fine detail, and you're left with a simple question - does it save more space to compress it? Or does it save more space to store it in an analogue format? I'll let you figure out the answer.

Blade Runner Workprint question
Time

The version on the "right" is a copy, plain and simple, the "shadow bars" have nothing to do with the source being digitally modified. The original workprint - as is well established - was a 70mm print. At least the version is actually on DVD, after all it's only die-hard fans who care about, no one else wants nor needs to see that version of the film. I'd suspect that when the 70mm print was copied to 35mm, for some reason it was cropped at the top and bottom, and that process damaged the film somewhat resulting in the shadow bars. They could well have pulled both version from the same film under that understanding since the "shadow bars" showed them where the film was cropped when it was copied to 35mm. Or they might have known exactly how it was copied and done that on the few frames you see that are not colour-corrected and are heavily cropped. That's just a guess; remember people said the work-print was grainy in the theaters, so I don't think they used the best copying process they could when they showed it in theaters...

GOUT image stabilization - Released
Time

I was really impressed with ROTJ through this script, really makes it look on par with modern DVD transfers (maybe it was a lot easier to scan then the other two movies?) It's just a shame that SW and ESB suffer from more ghosting and a softer picture. I'd also forgotten to correctly set the subtitle placement, so I had to do it in the XVID stage (which wasn't a problem since the placement was off the picture completely - but it does reiterate the need to have this option preset so that people can decide if they want to leave it at non-anamorphic resolution, upscale to anamorphic or convert to a fully cropped 1:1 pixel ratio). In any case an incredible result, and somehow miles above the retail quality.

And the only reason I'm holding back the scripts is because ROTJ is not done yet. Some of the settings had to be different between SW and ESB, and I'm sure some will be different with ROTJ. I just didn't want the SW or ESB script applied to ROTJ, because I know it can be better. I just need some more time to work on it.

-G

When you do post you're new script I'd love to see what the differences are. I have completed encoding all movies using the current script, taking around 40hrs per movie. I suggest you add the option to export at a 720x304 size (since that is perfect for any MPEG-4 version) with subtitle placement adjusted accordingly. If you could also include a list of custom filters required it would help (I had to acquire them manually). It also seems as if some people don't realize that they don't need to let the script run for both "passes", anyone who's going to encode this is all you have to do: 1. open the .avs in vdubmod, 2. select "Save As", 3. Under "Video mode" choose "Direct stream copy", 4. Use the AVI instead of the AVS to encode.

I hope you'll continue to work on avisynth scripts for future HQ LD rips (should they come from Aleksbmw and/or others - but I believe they will), and for the 2004 SE (since once it's colour corrected a more modern "hybrid" version can be spliced together from either the GOUT or from other LD versions). Thanks for your work man, I know I've found it useful for my DVD's!

Darth Editous said:

They should have the same framing, but they don't.

Left/right cropping differences can be explained by the vagaries of analogue video capture (by which I mean the laserdisc rips being used for comparison).

Going by the fact that the cropping is exactly the same on SW and ESB and is only different in ROTJ makes me conclude they did something different for ROTJ. The video would have been an ntsc telecine as soon as the film was scanned - convention back in those days used a scanning process that directly produced a telecine by scanning odd and even lines in sequence (each frame is scanned twice, with the scanner picking up first the odd lines for the telecine, then the even lines).

Furthermore they probably fine-tuned their scanning scene-by-scene, and then edited the telecine so I would be very surprised if the master tape contains an uninterrupted 2:3 pull-down pattern... so conversion to PAL would have been very low quality (29.97fps --> 25fps). It's my guess that George Lucas Jr didn't care about the theatrical trilogy even in 1993 - and that this little exercise was more about how good the film looks and are they ready to do a 2K scan for the SE?

The video would not have been resized for Laserdisc after scanning since it was already an ntsc telecine. But I think Red5 may be right, because it does appear to be the same transfer in all other aspects (same colour, exactly the same top cropping, etc). For some reason they mastered it differently to the first two films, but from the 1993 THX ntsc telecine nonetheless.

Just 5 more hours to wait before the G-Force script completes on ROTJ (after that I still need to encode the XVID - but that'll take barely any time), I can't wait! Haven't watched the movie in like 3 years now.

Good screencaps. I don't see hard evidence one way or the other for what size the video was before it was put on DVD, however I still disagree about the same 1993 "DC" master being used on the GOUT. They should have the same framing, but they don't. I don't think the source had to have been PAL to obtain the fidelity we can see. They may have used the digital ntsc tapes produced by the scanning process, rather than the completed master. But that doesn't explain why the picture is cropped on the bottom on the GOUT.

The PAL "GOUT" is top, the NTSC "Laserdisc rip" is bottom, I think it's from the "Gonzo" set (which was converted to anamorphic, hence why the picture is vertically stretched). The main thing I noticed was that the cropping is different. More on the sides of the PAL, but less on the bottom. It doesn't necessarily mean that the GOUT came from a PAL source, but it certainly came from a different source than the 1993 DC laserdisc master tape.

Info Wanted: 70mm OT digital restoration? Are there any?
Time

Mielr said:

jfett said:


The 70mm is an upscale anyway, so what's the point?
I think even if the original negative is 35mm, a 70mm print is still preferable to a 35mm print due to the size of the frame and the grain structure within.

Maybe, but I doubt the film size is going to be the most important factor. After all, you can only digitize to 4k Max either way (on most scanners), you're not going to digitize to a higher spec. When a film is as old as Star Wars the film has aged, it has faded, and developed many, many scratches and possibly warping. It'll need to be professionally cleaned first. You'll need a highly calibrated set-up to scan the film, you're going to scan in four channels for every frame one exposure at a time R, G, B, IR (for infrared correction).

Problem of course is that while technology gets better, the film stock gets older. If you had a print in your possession, it's going to take a lot of money to get it looking anything like the 2004 retail DVD. It can't be done by one person on a shoe-string budget.

I'd never heard about this either. Those images have been resized, making it more difficult to tell. However, the source is most definitely not the same:

If anyone can upload some screencaps off the ntsc Jedi (mine are just from an LD rip), we can have a closer look at the detail. It doesn't seem counterintuitive to me that they used a different master tape for Jedi - it seems counterintuitive to me that they used what was probably a D-3 tape in 2006 to master a DVD instead of scanning the few Non-SE scenes required to convert the 2004 DVD to the theatrical version. Heck, maybe they couldn't find the 1993 "definitive Collection" master tape for Jedi and just used a different one.

But I didn't know that they released an English THX version in PAL, I'm under the impression that they only released PAL THX LD's in foreign language versions?

Lord Grievous said:


Is anyone interested in improving the GOUT DVDs as best as possible? I've seen several threads detailing how to do stabilizing, colour correcting and upscaling the image of these versions but I can't seem to find a single restoration project that does all this for all three movies.

I know that Moth3r did something similar for the GOUT Star Wars, but it's only for the first film :(

As far as laserdisc rips of the '93 Definitive Collector's Edition go, the GOUT is the best, it might not be what we expected but I'm yet to come across a better rip to start this project with.

What I'm suggesting is something like this:

1. use the retail PAL GOUT as a basis because it has slightly more resolution

2. stabilize and colour correct the image, and remove grain as much as possible (just compare these colour corrected images with the original GOUT: http://originaltrilogy.com/forum/topic.cfm/Methods-for-colour-matching-colour-grading/post/336687/#TopicPost336687)

3. create custom AC3 5.1 soundtrack based on the '97SE laserdiscs and '93 Collector's Edition

4. make them as 3 DVD9s

I'm not much of an AV editor myself but from what I've seen on these forums I know it's not a question of if it's possible but rather if anyone wants to do this?

So are there any dedicated AV'ers out there who want to do this?

Thanks,

LG

Why don't you do it yourself, if you're so passionate about it?

I'm not much of an AV'er either, but I still managed to get G-Force's script to work (manually finding and downloading the avisynth plugins one-by-one), resize it to a 1:1 pixel aspect ratio cause that's what I wanted and put the mono soundtrack on SW... it isn't hard. May take about 40hrs to encode per movie, but that's life. I have ESB at 60% encoded at the moment and about 14hrs remaining!

By the way this is what I did:
1. Rip DVD.
2. Use DGIndex to create dv2 file.
3. Prepare an altered "G-Force script" (this was the most involved step, there were three things I altered - 1. the video ratio, 2. the video size (no overscan), 3. the subtitle placement, but this rolls over into the next step.
4. Load said script in vdubmod, and check frames to ensure I'm happy with the result.
5. Save in vdubmod using the option "direct stream copy".
6. Wait for 40hrs.
7. Make AVS file, this was the contents:
AVISource("StarWars.avi")
AssumeFPS(23.976)

8. Use vdubmod to create XVID.
9. Use vdubmod to mux audio. (BeSweet was used to re-encode from a PAL "framerate" to an NTSC framerate).

PAL "gout" as a bias? Yes, because the overscan bars were removed. However this is a very small and negligible difference anyway. I'm not really a fan of removing grain, it was necessary because when I tried to keep it I didn't get the full benefits of the script, and also the picture is more "noisy" than "grainy" imho. More important is antialiasing if you ask me.

The "gout" is not an "LD rip", it is a DVD mastered from a digital tape previously used as a laserdisc master (probably D-3 tape since the audio format is 4 channel PCM and this is exactly what is on the LD in the form of 2 for the audio and 2 for the commentary track). Basically all they seemed to have done to it (besides using a different source for the SW crawl) was to IVTC it and then master it as a DVD using MPEG2/AC3. They didn't bother to convert the subtitles -although imo player invoked subtitles suck- or even to convert it to anamorphic (which really is inexplicable). It isn't the first DVD to be released from a laserdisc master tape, however most ld-based DVD releases were well before 2006. I'm pretty sure LFL didn't bother to scan anything pre-SE for the 2004 DVD since original pre-2004 SE elements are clearly evident on the release.

Why Lucas molested his movie I do not understand, but watching the SE "Jabba" scene just makes me think he's really lost the plot. If the dialog was more unique it may be interesting, but he almost reiterates word-for-word was Greedo said. Like putting Ian McDiarmid into ESB and making ridiculous new lines for him, I don't understand it, and Lucas himself seems to be the only fan of his SE.

Info Wanted: GOUT - Anyone done an anamorphic version? aka which version to get?

I used the PAL disc, however, I just found my old Laserdisc rips and the framing is identical. I'm not sure what set it is, but it is anamorphic and it has two soundtracks, the second is the commentary, the menu looks like this. Here's the screenshot. I was wondering if the Pwnage Edition used the 2004 disc for the non-SE scenes?

I attached the mono sound to it (setting the frame rate to 23.976fps and a delay to sync it), I believe you were involved in the creation or release of that soundtrack, no? Where can I find other mixes, like the theatrical stereo mix and theatrical tracks from the other movies? Is it only available through usenet?

Im thinking of releasing a blue ray format release also, since whats the point in IVTC the whole thing then cramming it back into interlaced for a dvd.
Progressive > interlaced. Technically by the way those owning the re release gout dvd can watch mine with no trouble since the master tape is basically the same.
As I'm sure you know, Lucasfilm made several "master tapes" for their various 1993 releases, only the one used to create the definitive edition (/faces) was used for the DVD. Capturing multiple releases would be useful as they could be edited to use the best quality video (though this has been done with the retail DVD as it is), but especially if there's an NTSC version that doesn't suffer from DVNR.

I know Mother already touched on this but I'll throw in my 2 cents. I don't know why people still bother releasing in the DVD format to be honest, if it was up to me I'd say simply encode it as an XVID, if you're cropping the video (which is probably necessary since otherwise the black borders affect picture quality on the edges in encoding) just resize it to 720 x 304 and let the player do the scaling. You can leave the soundtrack in AC3 format, while having the benefits of MPEG4 video. Releasing in DVD format is a waste of space when so many standalone players are compatible with XVID and DIVX anyway.

As far as IVTC is concerned, NTSC DVD's that are not progressive play back at 29.97fps on computers, and in 59.97i on DVD players (even if the movie "once was progressive") because as you well know the telecine pattern changes at any point because it was edited using an interlaced digital version of the movie. On a computer, the software blends the fields together so you effectively get pppii in a repeating pattern. Hence merely IVTCing the DVD and re-encoding as a progressive DVD will improve the playback quality, particularly on computer. I've also seen frame-blended encodes - for instance it's prevalent on the Brother's Keeper DVD. Using an avisynth script to remove it and restore it to 24p and then encoding will improve the quality whether it's watched progressively at 23.97fps or interlaced as NTSC (since the fidelity is preserved and not softened with frame blending).

I'd suggest using an avisynth filter (maybe a modified version of the G-Force script) before release, the two main benefits of the G-Force script are to reduce the image-shake and to antialias. The video quality, IMO, of the GOUT is still way below par even with the G-Force script applied, but at least it's a bit better. Maybe if Lucasfilm hadn't wasted their money on several different transfers in 1993, and instead only got one done they would have gotten a better result?

Are you planing on capturing any other Laserdiscs, besides Star Wars when you're done?

I'm a little confused, I thought G-Force only released a script, not a DVD?

I'm also confused by the, link in Mother's post above to pwnage edition, this is what the "GOUT" DVD looks like through G-Force's script (although I did modify it to produce a 1:1 pixel aspect ratio instead of 16x9) click here.

Why is my version cropped on the right?
