Hi,
As some other people, i'm here with hope of getting this support back to life!
Who, What, Why:
Me very shortly:
Works when available as computer scientist.
Works when i'm free
on musique composing, mastering, post production, distribution.
Analog life style fan.
Vinyl fan.
Laserdisc what it is:
I'm from the older generation who had chance to see in the 90's a laserdisc in my oncle's house...
So seeking to throw away that "s..t of diggigigiigital" (sorry got a bug) in the video perimeters (Yes all my audio is analog, no ever one DSP, only in the ADC/DAC for the synthesizer who are "digital" but no dsp, discret integrated analog component only...)
I was wondering how i could bring back to me this signal which is so warm and soft.
TV, digital low cost compressed signal.
Blue ray, no digital 4:2:0 heavy compressed, even a PIV is to slow to read it!!!
DVD, hum, pal/ntsc/interlaced, sounds analog but digital mpeg2 compressed.
Ok, now that all new technologies where not interesting, seeking in the old ones.
35mm, up to 8000*4000 digital px, real analog picture, real analog sound.
So what i'm doing here.....
Heu, one film take over 30 pounds in four to eigth full sized wheel, film cost a human, display device, cost one again. Definitively not possible for consumer of today. (Hey guy, ten buck for the used starwars ep4 in 35mm , possible?....
))
ok i will short circuit the other (VHS,8mm,16mm), even if the 16mm should be more investigated...
Back to me searching, remember oncle got a vinyl which was able to play video and sound...
So started to inform myself on the device: PAL/NTSC Full Analog at 440TVL with analog sounds.
Hey, that's interesting, so i went to the new world shop Ebay, to seek the beloved CLD D925 with one Laserdisc to test.
As i'm very lucky, the device came from the state of fully functional to fully KO.
Let me tell you that i went outside for some sport for a while....
After a long sleeping, that couldn't be like that. Opened the device, yep i can now open the tray manualy, put the laserdisc, play, and µ%¨£µ%¨£%, what i didn't know that laserdisc was one play support (It was carved from the start). In fact after little investigation, the head, was so out of his track that two laserdisc has gone.... After using clay, screwdriver, patience, and 3 days, i managed to get the side A working, no more auto reverse.... But stay in touch, i got the part, and won't give away, want A/B working, again, in fact it must because if i don't eject the laserdisc before the end, the head try to goes up, and i need to open the back side of the device to push the head in order for her to work again.... Hey, like vinyl
Why:
So, now, i' ve got the device which seems working, but how i connect this.
This part was easy as i got analog compatible device.
So component will be the first step.
Turn on the display (Hd ready), put on the left over laserdisc, and play.
Let me told you my first impression: Wow, it seems like a bluray, but more soft, fluid, and the color, how my god keep saturating the things, 200%, it still works
Try to saturate a blue ray to 200%, yellow come to life, after green, that red ,and blue, with about 16 colors on the display and luminence...
The sound, what to tell about, it the best i ever hear in digital, of course in stereo. Shame that these guy didn't understood what would came regarding the digital age, and skip the analog sound for digital.
So, AC3 what for, i'm not interested.
But lucky, i am, Laserdisc is capable of true analog sound, and has support recorded in with...
I read that some laserdisc analog tracks can explode all that exist, and a lot of laserdisc analog track are good for trash...
But it's more due to the digital who was in the head of people in hese days rather than being limited by the technology.
Did you know that VHS has CD or more sound quality as it is analog!
So, you will tell me that blue ray is 1920*1080 and the laserdisc is about 440TVL, it's impossible to have the same result.
Ok guy, a little technical speech:
Blue ray is a 4:2:0 sampled source with H264 compression methods. Which faster result in block of 16*16px. So your pixel is very big mister. also 4:2:0 told us that only the Y' is about 1920*1080 , U, and V are 960*540, yes you heard me Blue ray has signal which is a mixed resolution signal!!!!!!!!!!!!!!!!..............
Laserdisc is a full signal uncompressed! So basicaly you have picture like the 35mm but in a resolution a lot smaller.
I can't well told you what it does in px because analog cannot be compared to digital in term of measurement.
I read a lot of thing and, i can only told you that 400/440/1080 TVL ar what it goes out from the device.
But as vinyl lover, i got the same issue with the vineyl and, after a lot of experimentations and measurements, 192Khz at 16 bit, will start keep the vinyl sound intact...
Basicaly 720*576 is an example but other say 384*588-440*576-768*576., and you know what 625VL is the pal signal, and there isn't any card which is capable of capturing these 625VL. and what about the 1080Vl of the laserdisc...
In fact don't try to digitalise the laserdisc, it's impossible. You nead at least a RGB 4:4:4 and that don't exist. Why, because some stupid and very intelligent men told that YUV 4:2:2 was sufficient for the eye. You know the same guys who told us that CD is better than anything else on the earth. Heu, why are you selling me blueray audio as the CD is the better support in the world....
Yes , people have defined standart to poor for capturing analog video. I have a 720*576 PAL/NTSC YUV 4:2:2 capture card , and the result in always bader than the analog in from my device also take into account that digital playing of laserdisc involve desinterlacing, resizing, the only things positive are the denoiser and the 3d.

Hi,
It's not possible to capture RGB 4:4:4 in SD so you won't be able to do this.

Hi,
Thanks for getting back to me.
I can confirm that it is not possible to capture up to 1080 using s-video.

Hi,
I'm sorry to say that we don't have anything capable of that.

So basicaly the laserdisc in analog is the blueray in digital with better signal.
Good, i have my support the laserdisc, ok, i want to see the bridge of spy. Ohoh, sorry man we don't produce anything on this device.
Also what we can here, it's obsolete technology, come to me my friend follow my in the digital edge, no freedom, robot visual, and money robber....
Same as people telling that vinyl is outdated.
These people don't have the device, and don't know what they are saying, there only robot who repeat what other are saying.
And you know what, before trying the laserdisc i was one of them....
Did you know that signal in the space are transported by analog signal ?
http://www.midilibre.fr/2016/09/03/un-p ... 387976.phpDid you know that a laserdisc, if it was possible to capture it correctly cost about 150Gb byte of space for 2 hours of film ?
Yes man, when you watch a laserdisc you throw in your face 150Gb of data.... Don't ever dream of digital counterpart!
So i can discuss years and years to convince you as i analysed each part of this technology and will be happy to if you want but these reasons are sufficient:
Today you haven't the choice, you want to watch a film: Digital is the only way from your home to theather with compressed unatural material.
You never own the film as the source isn't preserved (a lot of digital processing is done), and today this is rental by streaming, etc...
Digital Technology is at his begining and change every 4-5 years, so you won't be able to have any collection. (VCD-DVD-Bluray-UHD Bluray, etc...)
Durability of digital is lesser than a laserdisc. I got laserdisc that have 25 years and still works, could you tell the same thing with digital.
No zoning , tracking.
And the support, a gold 12 inch vinyl, with cover of 12inch and a lot of space for artworks...
In finnish,pressing laserdisc involve a lot of competences whoses result in quality process with normalisation. Don't you ever thought that all blue ray seems to look different and you have to correct all the time the display settings to have the best of it...
An for the last ones, each time you watch a laserdisc, it is the same things as for the vinyl, it's different, the devices involved, the laserdisc keeping and age are making the support come to life.
Ok, you convinced my, but what i'm loosing of i buy laserdisc ?
Virtualy nothing, you have even more today:
Sound:
5.1 in standard via AC3RF. (Today device, are not fully ac3, and you need a converter, but in the future it will be integrated in the devices)
2.0 digital in standard throught analog or spdif output.
And what i love at most: 2.0 analog in standard throught analog or spdif output.
It is also possible to do 3.0 via the stereo signal.
Chapters comes in standard.
Subtitle: 4 languages are possibles.
Bonus, a side is about 60mn in clv, a lot of film have 3 faces, one face in empty for ... why not bonus...
Some record already have bonus like trailers, comments, etc...
Ah, for me the only thing that count is the resolution, what you have for me?
Hi vision man, hi-vision... (Also hi-vision involve special device, but in the part 2 of the project, we will also include it in the device)
What for the future?
Still want more, the technology is about 40 years, and there is no limit to analog signal, the only matter is the storage, and the device display. I'm convinced that we can easily goes for 2160Vl even 4320Vl and with today electronics improvement at lower price. But this will invovle a new add-on...
Everything is setup.
We only need to produce again the hardware with improved part for digital age for all the consumer. Part 2 of the project
Keep the community alive by producing again new/old software (laserdisc). Part 1 of the project.
I'm trying to contact compagnies for this. And i've got suprise as they aswered me.

Hello,
Thank you for your interest in Participant Media and Bridge of Spies. Unfortunately, Participant is not involved in that aspect of the film's production. Distribution of the film is handled by Walt Disney Studios in the US and by 20th Century Fox internationally. My apologies that I can't be of greater help.
All the best,
Ethan Senser

Bonjour,
Désolé, nous ne pressons pas de laserdisc.
Bonne recherche.
Bien cordialement

goelette.images@orange.frToday, we won't have issue with licences as it is like producing vinyl, everyone can do it with the proper materials.
Please help me ? :prie:
I need people who were involved in the process in order the define the needs, before requesting kickstarter funding.
I know that the more diffcult is the master (white room), pressing can be made at home.
But don't worry, we will do the things correctly, we will build the first plant of laserdisc from decade.
Cost estimated about 100 millions $, if we can involve 4 Millions worldwide customers at 25€, that's done and they will have the first new laserdisc pressed for this....
