And, they were analog!

CDs, DVDs, and of course BluRays are digital, but laserdisc was analog.

[-] acockworkorange@mander.xyz 17 points 2 months ago

I didn’t know that. Always assumed it was like a big CD.

[-] sep@lemmy.world 11 points 2 months ago

Laserdisc had 4 audio tracks 2 digital and 2 analog. The digital tracks was what later became the cd. The analog tracks was often used by audio commentary along the movie and such.

[-] Kusimulkku@lemm.ee 3 points 2 months ago

I think digital audio was only added in 1985

[-] sep@lemmy.world 1 points 2 months ago

I think true, but most discs i have, has digital audio.

[-] RalphWolf@lemmy.world 9 points 2 months ago

Right??? I learned that about a year ago. I'm impressed they even made it work.

[-] ripcord@lemmy.world 39 points 2 months ago

Wait until you learn about SelectaVision, the vinyl record that played videos and still used a stylus.

[-] kernelle@lemmy.world 19 points 2 months ago

30 cm diameter

450 rpm for NTSC, 375 rpm for PAL

Oh so it's a helicopter

[-] computergeek125@lemmy.world 2 points 2 months ago* (last edited 2 months ago)

LaserDisc ran at up to 1800 RPM also in a 30cm form factor

In the Tech Connections video on them, they sound like they're taking off when they spool up.

A very good friend of mine had one of these when I was a kid. We called it laserdisc. I couldn’t tell you how that started.

So, when I got to high school and they were using actual laserdiscs I said, “Where’s the cool outer shell? Is this just like, a school laserdisc setup?” Some kids argued with me that I didn’t know what I was talking about.

I clearly remembered watching Star Wars on them and being mesmerized by that case.

Years later I got to thinking about it and googled “laserdisc with hard casing, mechanism removes disc when played”. Nothing. I chalked it up to it being some kind of false memory. Maybe I was just remembering the sleeve and my buddy was putting the movies in the player in a way that made me think it worked like that.

It wasn’t until years later that I seen a techmoan video in my feed and I was like, “THAT!! That’s what I’ve been talking about all these years!! It’s fucking vinyl! NO WAY!”

I was always tech obsessed so it nearly drove me crazy anytime I thought about it. He’d been dead for years so I couldn’t ask him. His dad and sister had no idea what I was talking about. “He traded a lot stuff around so there’s no telling what he had. There was mismatched technology all over this place.”

[-] SomeGuy69@lemmy.world 2 points 2 months ago

Woah! Crazy that something like that existed.

Bit of a late entry, but since you took the time: first LD I watched was "Raising Arizona". Art teacher in high school was an enthusiast.

[-] 9point6@lemmy.world 29 points 2 months ago

ITT: people who watch technology connections and techmoan

[-] ripcord@lemmy.world 1 points 2 months ago

It was weird, I wasn't old enough to have SelectaVision and only barely knew about LaserDisc. But I love dead tech formats and learned about them later. I have a modestly big collection of Laserdisc and CEC disks and several players. About 10 years ago you could find lots of them for sale for relatively cheap, too.

So it was super gratifying to see the Techmoan/Technology Connections videos not terribly long after I got into them :)

s/o to LaserDisc for being one of the many sources of de-specialized Star Wars

[-] BigDanishGuy@sh.itjust.works 2 points 2 months ago

one of the many sources of de-specialized Star Wars

What are the others? I mean besides VHS? I was under the impression that the laserdisc rip was the only decent quality release of the original trilogy.

[-] Rai@lemmy.dbzer0.com 2 points 2 months ago

MySpleen has it, I think 60GB for all three. Tough to get in now, though D:

[-] brbposting@sh.itjust.works 1 points 2 months ago

One example, Harmy’s:

  1. 2011 Blu-Ray release with fan color correction
  2. 2006 DVD bonus content from 1993 Laser Disc, upscaled by fans
  3. 720p HDTV rip of 2004 DVD version
  4. Digital TV capture of 1997 Special Edition
  5. Various high-quality film scans and special effects elements
  6. Team Negative1's 35mm film scan of Mos Eisley sequence
  7. 16mm film transfer of original 1977 theatrical release

The sheer amount of work…

When you have nineteen minutes, check this out! Really well-made overview of this whole Harmy business.

[-] BigDanishGuy@sh.itjust.works 2 points 2 months ago

That's frigging crazy as well as awesome. Last I went looking was probably like 15 or 20 years ago. And back then I didn't learn about Harmy. Thanks for letting me know. I really believed that the laserdisc version was the only way to get rid of the crap Lucas added when he discovered Adderall and cgi in the late 90s.

As a stand up law abiding citizen I will of course refrain from seeking out these unlicensed materials ;)

There's our favourite midwestern's take on it.

And Anders Enger Jensen made a brilliant synth song remixing the an instruction video about DiscoVision:

I sold a player on eBay last year, mfw the buyer also bought the aftermarket warranty.

[-] Swedneck@discuss.tchncs.de 7 points 2 months ago

at this point "discovision" is a trigger word for me, instantly my brain is consumed by that one song

[-] sep@lemmy.world 5 points 2 months ago

Still have my laserdisc collection. It is just collecting dust. But I do not have the heart to part with them.

[-] arin@lemmy.world 5 points 2 months ago

Both are good

Man that person in the thumbnail has really small hands. (joking.)
