 (Edited)

_,,,^..^,,,_ presents the [SET ruLes] project

Special Edition Trilogy restored using Laserdisc editions


Project mission: restore the 1997 Special Edition Trilogy using audio and video from various Laserdisc editions.

Video sources: analog video captured directly from Laserdiscs; other analog sources are admitted (VHS, CED, VHD, Beta etc.) only if the material is not present on the Laserdisc format.

Audio sources: uncompressed PCM and AC3 soundtracks captured directly from Laserdiscs; DTS Digital Surround theatrical soundtrack from CD-ROMs, other analog sources are admitted (like VHS, vynil etc.) only if the material is not present on the Laserdisc format.

Subtitles sources: Project Threepio (for english and german), literal subs for italian.

Project prohibition: to use DVD, BD, DVB, HDTV or any other audio or video from any digital sources; exception is DTS original theatrical soundtrack, because it was originally released on theaters and never commercially availble after that, and because it is of the same kind (bitrate, bit depth, frequency) of any other laserdisc DTS soundtrack.

Supplemental material: will be released in a future [ruLes] project.

Project status: RELEASED

Captures:

testing various combination of laserdisc players (different models and units), DVD recorders (different models) and comb filter settings, connection methods (S-Video and composite, RCA and BNC) and brands.

After many tests, I decided to use only the Pioneer CLD-D925 as its video quality (resolution, noise, drop outs) is better than the others; the connection used is S-Video, as the laserdisc player comb filter is better than the capture card's.

 

Video treatment:

all laserdisc video captures will be time and space aligned, then with AviSynth median and average scripts will be overlayed to eliminate some noise and drop-outs, and put out unwanted video parts (as burned subtitles); color correction, at the contrary of OUT, was necessary... after many tests, I found the best compromise to retain the original colors when correct, and to correct them when wrong - in particular during the Tantive corridors initial scenes and Mos Eisley; little noise reduction and sharpen; upconversion from PAL 720x576 4:3 to 1280x720 16:9.

 

Video tracks:

  • the original video format is 720x576@25fps 2.25:1 letterbox PAL, with a video resolution of visible image around 700x340, captured using the HuffYUV lossless codec; video is upconverted to 1280x568@23.976fps 2.25:1 as source, inside a 1280x720pixel 16:9 frame, using x264 codec and compressed at 8000kbps.

 

Audio treatment:

the original soundtracks are: laserdisc PCM 16bit 44.1KHz 1441kbps stereo, Dolby Surround encoded; laserdisc AC3 16bit 48KHz 384kbps 5.1 surround; DTS CD-ROMs 16bit 44.1KHz 1441kbps 5.1 surround; VHS HiFi recorded in PCM 16bit 44.1KHz 1441kbps stereo, Dolby Surround encoded.

All the soundtracks will be converted only when necessary; the conversions will be: from PAL 25fps to 23.976fps (pitch corrected when needed); from 44.1KHz to 48KHz; from PCM 1441kbps to AC3 384kbps; from DTS 16bit 44.1KHz 1441kbps to DTS 16bit 48KH 1536kbps and 768kbps. Only minimal treatments will be done, right for the conversions (NO audio enhancement).

 

AVCHD Audio tracks:

  • english soundtrack from NTSC THX laserdisc, AC3 5.1 Dolby Digital 384kbps 48KHz
  • english soundtrack from english PAL THX laserdisc, AC3 2.0 Dolby Surround Encoded 384kbps 48KHz

 

BD Audio tracks:

  • english theatrical soundtrack from CD-ROMs, DTS 5.1 Digital Surround 1536kbps 48KHz
  • english soundtrack from NTSC THX laserdisc, AC3 5.1 Dolby Digital 384kbps 48KHz
  • english soundtrack from english PAL THX laserdisc, AC3 2.0 Dolby Surround Encoded 384kbps 48KHz
  • german soundtrack from german PAL THX laserdisc, AC3 2.0 Dolby Surround Encoded 384kbps 48KHz
  • italian soundtrack from italian PAL VHS HiFi Stereo, AC3 2.0 Dolby Surround Encoded 384kbps 48KHz

 

Subtitles: to be refined; SRT format, both full and forced, English, German, Italian; French and Spanish will follow.

Subtitles tracks:

  • english full 100% literal - from threepio project
  • english forced 100% literal - from threepio project
  • german full
  • german forced
  • italian full 100% literal - adapted by me from the italian script
  • italian forced 100% literal - adapted by me from the italian script

 

Conversion from 25p to 23.976p: done with TsMuxeR

Final formats:

  • AVCHD folder, 720p/23.976fps with two english audio tracks and six subtitles (three forced and three full)
  • BD folder, 720p/23.976fps with five audio tracks (including DTS theatrical one) and six subtitles (three forced and three full)

 

  • other formats will maybe available in the future

 

Actually AVCHD and BD are both available on myspleen.

ATTENTION: to view the AVCHD version of SW:ANH [SET ruLes 1.0] correctly, it should be burned onto a DVD9 or BD-R, and played on a stand-alone BD player or a Playstation 3! - To view the BD version of SW:ANH [SET ruLes 1.0] correctly, it should be burned onto a BD-R, and played on a stand-alone BD player or a Playstation 3!


Jobs to do for the next version:

  • french and german literal subtitles synchronization
  • adding eventual subtitles in other languages
  • adding the eventual french and spanish soundtrack, if could be found
  • correct eventual video, audio, subs errors

 

To do later:

  • author AVCHD, DVD, Blu-Ray discs properly (menus, audio and sub tracks etc.)
  • provide opening crawl in german and italian (A LOT later...)

Self comments: There is no official DVD or Blu-Ray disc of the 1997 Special Edition trilogy (and never will be, I'm afraid to add); thankfully there are many DVB broadcasting around, released on DVD (like GKAR, TB, Reivax, Flunk)... but all of them have some of the following problems: MPEG2 "blockiness", compression artifacts, motion smear, image too sharpened or blurred, wrong colors, missing frames, burnt-in subtitles, PAL wrong audio speed, low bitrate, only one or two audio languages, not the best audio quality, lack of subtitles (check my own post here about these issues).

What I'd like to achieve is: eliminate compression artifacts, minimize motion smear (if possible), have the "right" image (not too sharp, not too blurred), correct colors, keep all the possible frames intact (as there are three different edition involved, it's feasible), retain only soft subtitles and not burnt-in ones (especially inside the picture), set proper audio/video speed @23.976fps, set the best bitrate available for any given format (minimum 7500kbps video bitrate for AVCHD and BD with 1280x720 resolution), add some interesting audio soundtracks (DTS theatrical, AC3 5.1, PCM Dolby Surround) in different languages, plus add several subtitles, including proper italian one.

Does this mean you aren't going to finish capturing the OUT?

Yesterday I finished my first "test capture day" of SET ruLes!

I tested the Pioneer LD-V4300D (unit #2, as in my first laserdisc capture comparison test, done more than a year ago, someone told me that the unit I used that time, #1, may have some problems); with and without both the DVD recorders (used simply as comb filters), and different connections (S-Video, RCA, BNC); I used the french and the german laserdiscs, captured small portion (2 minutes) of the same scene, then aligned temporally and spatially, then took the GKAR DVD and converted to AVI, for comparison - no other manipulation was made on the GKAR.

These are some of my conclusions:

  • the 1997 SE has all the four sides cropped, compared to OT ... indeed, its picture is zoomed, too - as the image is 340pixels high, vs 324pixels of the OT THX laserdiscs...
  • the LD-V4300D seems to have less details than the CLD-D925 (unit #1) I used for OUT, as I made direct comparisons between the same scenes captured with both the players (with 4300 yesterday, with 925 a year ago)...
  • the BNC output seems slightly better than the RCA - maybe due to the better connections
  • the colors are wrong - as many here have noted, white is often either blueish or pinkish, but wait... maybe I found where the problem lies, and a solution... follow me!

 

Well, my capture card internal comb filter is good, but not the best; the direct connection of the 4300 (as it was for the 925) is worst than the S-Video; as the 4300 has not a S-Video out, but only the composite out (RCA and BNC) and RGB (yes, maybe I have to test it too...) the only solution is to feed the composite laserdisc player output to an external comb filter, and here the two DVD recorders come in help!

The Panasonic DMR-ES15 has a better comb filter than my capture card, but no settings at all, so I take my Pioneer DVR-320S out of a dusty closet where it was sleeping for a long time, and, surprise! It has a lot of comb filter settings, that I forgot he had!

Between them, there is an interesting one: white AGC (stands for automatic gain control). I capture with the white AGC on, and the colors are wrong - as through the Panasonic and direct composite to capture card, BUT... if I turn it off, and set the white and black to the max... BAM, the colors are right - or, at least, better than with AGC on, and similar to OT. So the problem could lies in the white AGC, that maybe must be included in a lot of comb filters, like capture cards, TV sets etc.. or, because the Pioneer DVD recorder comb filter has so many settings, that set the white and black level at the max, it helps to recover the original colors (or most part of it)... I don't know, I'll leave this problem to the experts!

I managed to do the following comparison with avisynth and virtualdub: I took two different captures - french through the 320 S-video, AGC off, no color correction, and german through ES15, with saturation=0.8 - then overlaid the two (the alignment IS NOT perfect, because taken from two different A/D converter, so the two captures have different widths, but hey, this is just a test), then enhanched with the script I used for [OUT ruLes] - the one with the new denoiser; at the end, resized to match the GKAR height. GKAR, as written before, was only converted from MPEG2 to AVI using HuffYUV - as the laserdisc captures.

The wall on the left is white on SET, blue on GKAR; the light on right is white on SET, pink on GKAR.

 

Wall is white on SET, pink on GKAR, but Vader's buttons are less detailed, and...

what is that gibberish on GKAR's picture, bottom right?!?

 

OK, I admit SET lacks details also if its picture is enhanced, but, as explained before, it *could* be because the laserdisc player used for the captures is not the best OR the very unit I used is faulty; because the spatial alignment is not that perfect; because there are only two captures instead of three... I'm trying to find some other excuses, but maybe the missing details are due only to the fact that those laserdiscs could resolve about 544x340=184960pixels, where GKAR has 704x416=292864pixels... so GKAR DVD has about 50% more resolution than the SE laserdiscs... I'll find out the truth!

But, as you could see, no blockiness, no compression artifacts, better colors... hope to find a better capture method, to improve resolution.

Soon other capture tests...

Absolutely not! It means that, as I worked A LOT with ANH for the [OUT ruLes] project, now I know its reel changes, missing frames etc. and my mind is "fresh" enough to work on another ANH, this time the 1997 SE... if I finish all the OUT and then begin the SET, I'll surely forget many many things...

After I've done the ANH SET, I'll go for TESB OUT, then TESB SET, then ROTJ OUT, then ROTJ SET... at the end, if I will be still alive (xx_), I'm thinking about TPM [ruLes] using the (second) best laserdisc ever made, and two different copies of the laserdisc.

Talking about it (the Pioneer HLD-X9), if someone would be so kind to provide me the OT Technidisc laserdiscs, I could capture them with it...

BTW, my DTS syncs are almost prepared for you, I'll PM you when they're available.

Perfect, thanks a lot! Your work is precious for my project, really!

Oversharpening artefacts in the source + digital broadcast compression artefacts. At least that's what I think.

Anyway, nice idea and looking forward to see the results of this project!

Yeah, there is a lot of that going on throughout, kind of ruins the experience for me. Even after running deblock/dithering filters in AviSynth it still looks poor in places.

OK, I admit SET lacks details also if its picture is enhanced, but, as explained before, it *could* be because the laserdisc player used for the captures is not the best OR the very unit I used is faulty; because the spatial alignment is not that perfect; because there are only two captures instead of three...

I'll find out the truth!

I think that's your reason right there. The broadcast versions are all anamorphic, so have much more vertical resolution than the letterboxed laserdiscs. I'd much rather watch with a 'clean' picture missing some very fine detail than one that has it but is covered with digital artifacts!

But, as you could see, no blockiness, no compression artifacts, better colors... hope to find a better capture method, to improve resolution.

Are you going to remove the awful pink tint from certain scenes on Tatooine? I've never seen a '97 release that doesn't have it.

I'm thinking about TPM [ruLes] using the (second) best laserdisc ever made, and two different copies of the laserdisc.

That would be excellent, the laserdisc has the theatrical cut, I believe, and we have the DTS audio for that also, but only a digital broadcast to sync it to.

BTW, my DTS syncs are almost prepared for you, I'll PM you when they're available.

Perfect, thanks a lot! Your work is precious for my project, really!

My pleasure, of course. Seeing as you're using PAL sources it should be easy to make your SET ruLes project conform to the 'standards' we have set in the other thread, which is basically just reel change frame numbers, and will mean any audio you create can be used for other projects (my audio has been to conformed to the numbers there), and other audio could be applied to your video (such as other language tracks) in future.

I'm also happy to lend any other assistance should you need it on the audio front ;)

I know that "gibberish" were digital compression artifacts... I wanted only to test your attention (^^,)

Infact, I started to watch GKAR ("know your enemy...") but after some minutes I stopped; it's true that the resolution is there, but also many distracting artifacts, and wrong colors...

I'm curious to see the results of my project, too!

Man I wish I knew what language nearly everyone in this preservation area was speaking. Most of it is beyond my puny comprehension. However, what I do understand is that you are creating something I desire very much, and I can't wait to see it. There are so many versions of this project that are currently taking place, but I can't wait to grab one that is finished. Given your speed with the previous project and your promises with this one, I am indeed excited. Good luck :)

You can't miss them. Its present on certain shots on Tatooine, but the biggest examples are the CG 'enhanced' shots on the entrance to Mos Eisley, for example (from the UK PAL laserdisc set):

And a shot that I have attempted colour-correction for purpose of comparison:

Its inconsistent from shot to shot, though. Some shots (such as the shots when they park up outside the cantina) don't suffer from this, but then shots afterwards do. Just aim for any CG-altered shot in the first half of the film and it'll probably be pink, even if only a small amount.

Here you are fast test I made right now; GKAR is converted from VOB to AVI (with DVD2AVI) then reduced to 704x340 to match captures resolution.

Captures are rough, taken with Pioneer CLD-600#1 composite to Pioneer DVR-320s, from there to PC via Svideo; source French THX laserdisc.

 

Test2 color is pretty good.

Further testing on monday, "second capture test day" of SET ruLes!

Test 2 is definitely the best of those in terms of colour, although it does look a bit desaturated, which may explain the difference. I'm wondering about the picture quality, how does it look on the D925? These CLD-600 shots look a bit soft and fuzzy.

Also, what differences are there between test 1 and test 2 that has resulted in different colours?

Author
Time

Test 2 has the same settings than test 1, apart saturation, so you are right... when saturation is applied on test 2, it is like test 1 - pinkish...

So, I stacked test 2 and test 2 with saturation, and applied the VDub gradation curves filter, and here you are the results:

This is the only setting I touched on the filter:

Must be tested further, but maybe this is the way to go...

About CLD-600: its image is definitely too soft... is it its own fault, or is it the Pioneer DVD recorder's comb filter - which, by the way, has the detail setting at max?

Definitely too green, but you're getting the idea. You also need to be careful to select those shots that are pink, eg: a normal shot between two 'pink' shots would appear too green. Some shots aren't as pink as others either.

About CLD-600: its image is definitely too soft... is it its own fault, or is it the Pioneer DVD recorder's comb filter - which, by the way, has the detail setting at max?

It may quite possibly be the player, although I haven't had any experience with it. A quick Google search to a popular Laserdisc archiving web site shows it as a lower-end model, which may be why the image is so soft.

I'd stick with the D925, its supposedly one of the best PAL decks there is.

Too green. WAY too green

yes, I know, it was made this morning (was half asleep)... I forgot to add further tests... here they are:

YUV, chroma R and B changed - still too pinkish

 

HSV, saturation and value changed - colors quite good

 

RGB, green and blu changed - still too green

 

YUV, chroma R and B changed - too blue

 

Now, what is the image with the least uncorrect colors?

Is it possible to know which method is used for color correction?

And, did you color correct the whole movie, only selected scenes with the same settings, or selected scenes with different settings?

It's quite complicated actually. Not like our GOUT project but still.

I did it all in avisynth. Since there was a lot of blue and cyan in the 97 SE I first used selectivecolour to lower those colors a bit. Then I made histogram files for colourlike, using some shots from the 97 SE and some from theatrical prints like the Senator screening.

I then made a 50/50 of the histogram conversion result and the cyan/blue fix so I got the best of both and finally, I made an additional RGB curve to correct the pink tint in the Mos Eisley scenes.

I admire your hard work! But it's too much for me... my restoration experience is limited, and my time too, as I have family, a dayjob, and... cats! ,,,^..^,,, and I'd like to release this project ASAP.

But some color correction is needed, so I tested a lot, and find a simple, but effective, method; merge the original laserdisc image (that is less pinkish than GKAR. by the way) with the same image, auto color corrected. I know it's not the perfect, definitive solution, just only a compromise - but a working compromise is better than pinkish images! (^^,)

Well, let me explains some of my later tests: I captured the french laserdisc (side 1 for the moment) with three different players, directly without passing through any dvd recorder; the players used are all Pioneer, CLD-D925 via S-Video, LD-V4300D and CLD-600 via composite; then I averaged/median the three captures, to obtain less noise; then I averaged/median the resulted image with the auto color corrected one. For comparison, I used GKAR, unprocessed, only converted from DVD to AVI (Lagarith YV12) using DVD2AVI.

Here you are some screenshots: top left image is raw capture from CLD-600; top right is the same capture, enhanced; bottom left is the average/median result of the three captures, enhanced, color corrected, resized to match GKAR; bottom right is GKAR, unprocessed. As I wrote before, the GKAR picture is always pinkish, while the laserdisc is pinkish only sometimes - at least in this side... obviously, GKAR has a better definition.

 

Starship is white on SET, pink on GKAR; planet is brown on SET, pink on GKAR; engine booster is right in SET.

 

Wall is white on SET, pinkish on GKAR; C3 is golden on SET, golden-ish on GKAR

 

Stormtrooper is white on SET, pink on GKAR

 

Darth Vader is black on SET, dark violet on GKAR

 

Leia's face color is more natural on SET, and whites are "whiter"

 

Sand is yellow in SET, orange-pink in GKAR

 

R2 is white in SET, pinkish in GKAR; the rocks color in SET is more similar to OT

 

I don't know if, in GKAR desert, they are sand waves, or MPEG waves... really, I'm not joking!

 

Maybe Luke is a bit pale on SET, but better pale than sunburnt as in GKAR!

 

The ground is brown in SET, violet in GKAR

 

Note RD's dome; still silver on SET, but what color is on GKAR?

 

C3 is golden on SET, pinkish on GKAR; in GKAR Luke's clothes are pink instead of white

 

Still working to improve the quality of the laserdisc captures; I'm almost sure that using three different editions (french, english, german) the noise will be lower; as the picture of 4300 and 600 is noisier and less detailed, I think I'll use only the 925 for all the captures - but I could also test the DVL-909, and maybe give a try on the Philips LDP-600WS...

OR, I could try the "extreme capture experiment (version 1)":

  1. capture three times each edition; TOOT them to avoid drop-outs
  2. repeat for three laserdisc editions
  3. results are three TOOTed captures, one for each edition
  4. average the three TOOTed captures
  5. repeat for at least three laserdisc players
  6. results are three averaged captures, one for each laserdisc player
  7. median the three averaged captures

    totalling 27 captures (each 3 sides) = at least 54 hours of captures, and about 1.5TB of hard drive!

    Any idea or experience to share?

    While the untouched capture has rainbowing, noise and stuff, for some reason the enhanced versions have halos around edges, looking a bit like edge enhancement. For example in the first shot, the edges are sharp and clean in the first pic and in the enhanced there's dark lines running along the edges of the moon and the star destroyer.

    Maybe something went wrong when you did the median? Were the captures perfectly aligned?

    You_Too, here you are another image - this time PNG, 1,2MB, maybe the JPEG compression made the problem worst last time... there are four versions: top left, 925 enhanced; top right, average NOT enhanced; bottom, two slightly different enhanced versions: could you tell me where the problem lies, and if the enhanced is a little better than before?

    If there are dark lines along edges on the first pic, the fault lies in the enhancement script; if there are on the second pic then the fault is on the capture alignment - that for this test was offset by 1 pixel on chroma on one capture; if there are in the one (or both) of the bottom pics, the problem lies in enhancement AND average...

    That is why sometimes is better to use only one laserdisc player (or at least the same model, different units) with different edtions, because the captures will be perfectly aligned.

    On the other hand, using different players, with different qualities and defects, result in an interesting mix when medianed and/or averaged, but more difficult to align perfectly. What do you think?

    And, thanks for the constructive feedback!

    All except the "average, color corrected" has the dark lines around edges. Maybe there's something with your "enhancement" that makes them look like that. In the "enhance script 2" pic, some stars has been filtered away too.

    Here's a gif animation of the two top pics with increased gamma so you can clearly see the difference:

    OK, let's dump enhance script #2...

    Can you point me to the best (in your opinion) avisynth enhancement script (sharpener, denoiser etc.), so I could build up a comparison, and eventually find a solution or some inspiration?

    I don't know if it would be wise to try and enhance it at all. Except for removing the rainbowing, or maybe the median does that?

    But if you wanna experiment, an interesting thing can be to upscale it to 720p, then add Msharpen(1) and downscale it again. Sometimes that digs up those very last tiny details.

    I made two test clips - one for OUT, one for SET; enhanced, upscaled and merged with unprocessed to smooth a bit the image.

    SENDSPACE

    results are not comparable to BD, but not bad, considering the source is laserdisc!

    SET lacks some details, because I used three different players (two of them with less resolution than the third) and only one edition; next time will be (almost surely) better, using the best player with three different editions.

    Feedbacks will be appreciated.
