Info Wanted: What fan project set is this?

s7en said:

The 'Makings ofs' on the Rowman discs are subtitle free. I can't find anything to back it up but I thought they were taken from the vhs releases. It's also worth noting that the two documentaries on the Jedi disc are at half resolution (352x480) to fit them both on a single DVD.


Rikter lists SW & ESB from domestic laserdisc and the Jedi two from VHS.

Did RowMan use the Blaksvn transfers?

 

adywan, I could probably post those next week if nobody else beats me to it

GOUT image stabilization - Released
Time

This project has given me the needed kick in the pants to finally try installing AviSynth on my Linux laptop under WINE, and I gotta say I'm likin' AviSynth already! Very cool.

Haven't tackled the encoding yet, but I can open the 3.09 AVS file in VirtualDubMod and step through frame by frame, albeit slowly.

 

Thanks again to dark_jedi for collecting the required filters in one place; however, I did have to download FFT3DFilter separately.

http://avisynth.org.ru/fft3dfilter/fft3dfilter211.zip

Was that line added to the script after dark_jedi uploaded the RAR? Or is it something peculiar with my WINE/Linux installation?

How to change HD to DVD?
Time

Laserman used to remind us that all DVD's are 'interlaced' in the sense that top & bottom fields are stored separately on the disc.

Would the same principle apply here?  In other words, your source file is called 1080i because its top & bottom fields are encoded separately.  However if each top and its associated bottom are from the same moment in time (same film frame) then you wouldn't see any combing.  Just a hypothesis....

When and in what format was the first time you saw Star Wars?
Time

Summer '77 at Glenwood Theatre in Overland Park, KS.  IIRC they didn't yet have a 70mm print on opening day, but got one later in the summer (before I went).

First saw ESB at the Midland in downtown Kansas City for a press-screening the night before general release.  Won tickets from WHB AM for answering the trivia question What did Vader refer to as a 'technological terror'?

Graduated high school in '83 and wasn't all that interested in ROTJ.  Maybe I thought I was supposed to have outgrown it by then.  I did eventually see it, but don't recall where.  It was some suburban cineplex with none of the atmosphere or ambience of the other two theaters.

 

Returned to Glenwood for ANH'97 not too long before they razed it.

Wow, I kinda forgot about this!                                                                                              Well, I did post ANH back in August.  Did you see that one Buster D?                                                                            But I forgot ESB & ROTJ until I see Hairy Henderson mention them in the other thread....

there's no such thing as Imgburn for mac is there?

FWIW I'm running ImgBurn on a Linux laptop, using WINE.

Wouldn't be surprised to learn OSX could do similar, but I've no direct experience.

 

Still waiting for .RAR's to download, although I was able to extract the .MDS file and open with ImgBurn.

Looks like the layer break is right smack dab in the middle.  Both layers exactly the same size.

I wonder if that corresponds to a cell boundary, or if there even exists such a thing in the BD-authoring world....

STAR WARS V8 - A Final Attempt (Released)
Time

RG-6 cable can span longer distance than RG-59, but I'd guess we'd be talking orders of magnitude longer than 2m before the losses become significant.

At 2m or less, I don't expect you'd see much difference.

 

If you had an external device like another LD or professional video monitor providing a sync signal, then I think you'd turn that switch on.

Without an external sync connected I believe you should leave that switch off so the player generates its own sync pulses from its internal clock.

Arnie.d said:

Can you explain how that can possibly make any difference?

 

Well that's a definite maybe....

 

Imagine standing in an empty hall and clapping your hands. The sound bounces back from the wall at the far end, and you hear it as an echo.

Well your BNC/RCA adapter behaves a little like the wall. Most of the electrical signal passes through the adapter as it should, but a small percentage is reflected back along the wire. Part of the signal bounces back from that point inside the adapter where the impedance changes just as sound waves bounce off the wall and ripples bounce back from the side of a pool.

back-reflection caused by impedance mismatch.

 

g-force said:

bouncing back and fourth between the mismatched impedance ends

 

Yes, that's the idea I'm trying to get at (don't know if it's correct or not ;)

Your current setup has impedance mismatch at both ends of the cable. [Yes, even with the "native" cable -- RCA cable to card's RCA jack -- there's still some impedance mismatch because of the physical properties of the RCA connector. The diameter of its centre pin prevents it from reaching 75Ω.] So the possibility of standing waves like G mentioned or multiple bounce-back-and-forths between the two "impedance boundaries."

With the alternative setup having a 75Ω BNC connector on the LD end of the cable, there's no impedance mismatch at that end -- hence no signal bouncing back from that interface, and no echo to be captured at the PC end.

 

Too bad Laserman isn' t in a position to give input. I'll bet he's tried it both ways already, but we're stuck reinventing the wheel through our own (your own) experiments. Nevertheless it seems worth a try to me....

The ebay link for the adapter is just what I mean.

The link for the BNC cable is RG-59. That might well have been what was used back in the day when your player was new. Today with cable modems and satellite TV boxes RG-6 is more prevalent than back then, and should be even better. They're both 75Ω, so backward-compatible in that sense. Even though you're not sending the very high frequecies associated with digital data, RG-6 might offer a slight advantages even at the lower frequencies of composite video. I found a USA vendor selling 2m RG-6 with BNC ends for $5. If you can find RG-6 for similar price, then why not?

 

Thank you for the pics. I'll show you mine ;) . . . as soon as I can beg, borrow or steal a camera or phone from somebody.

Arnie.d this sounds like a wonderful project you've undertaken.

I was disappointed when dark_jedi discontinued his second SC project, although his "HD2DVD" endeavors probably seemed like greener pastures to him at the time, and I can't fault him for that.

I'm very excited to see your results.

 

Two months ago I picked up an LD-V8000 thinking I might have a go at preserving a couple non-SW LD's. Prior to that I spent some time using the Dark/Sega ANH as an example while teaching myself manual IVTC using native Linux tools. I quit after the first reel, but to some degree I can feel your pain brother, and I don't envy you the task of IVTC'ing the whole movie.

 

Regarding haloing, do you suppose a cable impedance mismatch could be affecting it?

Didn't you say you're using a BNC/RCA adaptor? Would that be an RCA cable with BNC adaptor on the LD end?

I wonder if you'd get any different results using a true 75-Ohm BNC cable with the adaptor on the PC end?

 

Any chance you could post a snapshot of your LD-V800 rear panel? I'm curious to compare the connectors with my LD-V8000.

Info Wanted: "GOUT" is not "unaltered"!?!?!
Time

Original elements were used to make the SE, the same ones used to make the '77 film (GOUT). That's why their starfields match.

When the ANH crawl was composited in '81(?) they used a different starfield plate than '77, the same they had used for ESB.

Or maybe it was the same plate, only flipped or rotated or something.  I'm pretty sure Zion knows the answer, and you might find it with some searches.

 

I think you'll find the Japanese SC to match all other ANH laserdiscs in that respect.

Anyone have an x0 laserdisc player?

drfsupercenter said:

Oh, so if it's a 5.1 track, it gets downsampled to 2.0?

No it doesn't get downsampled. V8000 is incapable of decoding AC3. All it can do is play one of the other soundtracks on the disc, either stereo/matrixed PCM or analog mono.

drfsupercenter said:

What are those other things on the back that look like coax mixed with RCA? Is that some sort of obsolete video thing?

I guess you must be referring to the BNC jacks for sync signals in and out. They don't carry a video signal proper, only timing pulses.
In a professional environment where you might have several LD players under computer control (through the DB-15 serial port on the rear panel) you'd connect those BNC sync ports on all the players in daisy-chain fashion, keeping their respective video output signals in perfect synchronisation.
If you've got several players driving a single monitor that allows you to switch between them seamlessly. Or, if you've several players each driving its own monitor they won't drift out of sync with each other.

While LD-V8000 uses BNC ports only for sync signals, there are a few players that use BNC port for video output. Less noise than a yellow RCA video plug. (Because of its physical dimensions RCA plug can only approach 75 Ohms.) Among them are HLD-X0 and I think also LD-V4400.
reave, are you listening?

So what is the "digital audio output" on the V8000? I saw a picture of the back of it in eBay...

LD-V8000 doesn't have any digital outputs -- neither AC3 nor PCM nor S/PDIF -- only two sets of analog outputs.
It does contain a DAC circuit to decode PCM digital sound into analog and sends it out through those jacks labelled "digital".
They're analog signals coming out that set of jacks, but they're playing the soundtrack stored digitally on the disc.
The sound stored analog on the disc plays through the other set of jacks.
