The composite output of my Pioneer 704 looks FANTASTIC straight into my Sony 4K (55" 810C). The Video essentials moving zone plate test is ridiculously clear on all the problem areas. I was floored. The comb filter and upscaling on the Sony is amazing.

I've used a Panasonic DMR-ES10 with component out as well as a Sony RDR-GX255 with HDMI output and the bare composite into the Sony 4K wins head and shoulders above both. No comparison. Also, my Onkyo is supposed to upscale analog video to HDMI but that has never worked consistently and when it did the PQ was not great.

I was looking into getting one of those Leitch DPS units but after getting the new TV and seeing the results I had no desire to buy anything else to make LDs look better.

EDIT: Actually, I lied the composite is currently going through my Onkyo TX-SR705 and being output by the Onkyo as composite into the Sony 4K. However, I did initially test it straight in and it was superb (still is too!).


YMMV HTH FTW OMG!

Regarding newer 4k TVs, specifically Sony brand...

I used this site as a starting point for my settings: https://www.rtings.com/tv/reviews/sony/x810c

They have extensive information and tests for calibrating your TV/monitor. Where a lot of the info you see online is questionable I trust these guys due to the level of detail and extremes they go to with product testing.

Anyway, I've been tweaking settings back and forth for a while on this TV and feel like I've found the ideal settings for LD on this display (Sony XBR55X810C). This TV has memory for each input so you can set the Composite input correctly without affecting other inputs.

Aside from the actual picture settings which I made with Video Essentials, there were a few settings that I had not initially utilized until recently. Those settings being the "Motion Flow", "Cine Motion", and any kind of Noise Reduction.

Re-visiting the site linked above I was drawn to the section on 24p playback and motion interpolation. I had avoided these settings previously because I don't like the soap opera effect (SOE) and don't want to be adding fake frames that don't exist.

Then, after reading the individual sections by clicking on the "learn more" links I realized what this was; an inverse telecine circuit! As you can see in the review, my TV handles 24p over 60i. It is a 120Hz display so it will deal with anything you throw at it.

Basically, by setting "Motion Flow" to "True Cinema" and the "Cine Motion" to "High" you are detecting 24p content that has been telecine-ed to 60i, it reconstructs the original 24 frames and then uses the 120hz refresh to do a 5:5 conversion also preserving the original 24 FPS of the film. This has made a significant improvement in clarity and motion for me.

Sony has used these terms in previous models and they have not always had the same effect. They have, in the past, been synonymous with the SOE. Depending on your model the above info may not be accurate. I can tell you that on my display I'm not seeing the SOE and watching a LD feels normal.

In addition to that, which is huge, there are built-in noise reduction circuits for "Random Noise" and "Digital Noise". I've set "Digital Noise" to "High" and that has greatly improved titles that aren't as clean as some of the latter releases. Cleans them up really nice without artifacts. I don't notice any improvement with the built-in VNR on the CLD-D704 but I think that only applies to S-Video output anyway, which this TV does not have. If I toggle it on/off it doesn't seem to negatively affect a title that already looks decent so I leave it on for now (I'm watching the Connery Collection, Goldfinger and it looks great zoomed in).

Blacks are like midnight.
Colors and resolution are insane.
Motion is accurate.
SW zone plate is clear when still.
Zoom works great.

My only complaint is that there is overscan. I can't see the edge of the SW test plate in any direction. Feels punched in. Has nothing to do with the bezel (at least on the L/R sides). It isn't terrible but it ain't right either :(

Here is a cell phone photo of the screen so you can draw your own conclusions:

I hope that has been informative and maybe even helpful.

Posted: 14 Jun 2018, 16:39 

OEM power supplies are available from Astrodyne TDI in New Jersey. They are a US distributor of Chinese power supplies.

https://www.astrodynetdi.com/ecatalog/power-supplies/SPU45-103

https://www.astrodynetdi.com/pdf/SPU45.pdf

The DVDO VP50 uses this exact PS. It is rated for 6Vdc at 7A. The one in the picture has a 5 pin DIN but mine came with the exact DC coaxial connection for the VP50. Nice tight fit. You may want to talk to a service rep to make sure on the output connector. They were very helpful and great to deal with.

$85 US and like 6 weeks shipping for a single unit.

This should solve overheating problems and cheap PS that keep dying.

FYI - I bought a generic PS from eBay that claimed to be for the DVDO VP50 for $12. It did not power the unit at all.

Hope this helps someone ;)

Here is an article in the news from today at Engadget:

https://www.engadget.com/2019/02/06/ultraviolet-closure-digital-media-dvds/

Just mentally replace 'DVD' with 'LD' in your mind when you read it. Same point being made here regarding the streaming services going away and/or controlling the flow of content that is available.

Welcome to the Sony 4K club ;)

I'm glad people are realizing that modern TVs can present a nice image for LD out of the box. It may even rival magic boxes costing thousands of dollars. Maybe.

The fact that you may need a breakout cable moving forward is not ideal but as long as it works - it works. Glad you figured it out and thanks for sharing your experience.

With regard to AR settings on a Sony, as mentioned, you only really need "Normal" (4:3) and "Zoom" (1.78:1 Letterbox = Full Screen). A 2.35 movie would be correct on the Zoom setting. 1.66 movies are hard to get right however. I'll usually use the Normal 4:3 setting and know the top and bottom are slightly cropped. If you need to matte out burned in subtitles (Japanese movies) then you are SOL on that front.

Scaling is fine nothing to mention, like ringing.

I highly recommend looking up your TV or one you're looking to buy and seeing if it has the features you want/need at this website: https://www.rtings.com/

They do pretty deep testing and have good explanations of their findings and methods. Of note were the motion settings and Color Temperature settings.

Motion Settings for Sony's:
https://www.youtube.com/watch?v=CuEZIJDEQyo

According to these guys the Sony's are able to do inverse telecine on 60i signals then they do a 5:5 of the 24p for the 120Hz panel so you get smooth accurate motion. Not sure how they do on animation with odd cadences but the Looney Tunes stuff looks good to me. Comb filtering is about as good as it gets IMO. Colors are nice but don't "pop" as much as on my Faroudja.

M-Audio Transit will work. USB2 connection. Its old and probably cheap on Ebay. There is a new Pro version that will require an adapter since the optical input is on a mini connection. The new one probably has better drivers than the old version. Here is a link to the original model for reference. No affiliation. I have the old one and confirm it works as advertised.

https://www.amazon.com/M-AUDIO-Transit-Resolution-Mobile-Upgrade/dp/B0000CDHP5

Any MOTU interface with Toslink, like the Traveler, will work great also but is more expensive. I personally use a Traveler mk 1 myself and just did this the other day with come concert LDs. I've found these cheap locally on Craigslist. This will require a firewire connection but their newer products also have USB connectivity.

https://motu.com/products/motuaudio/traveler-old/

Ideally when you do the capture you should set the clock source to Optical/SPDIF or External so that the LD player is the sync master. This should help reduce jitter or noise. Setting should be 44.1KHz, 16 bit, Stereo.

Posted: 17 Aug 2019, 18:19 

I'm an audio engineer by trade. Its my main source of income. I've been doing this for 20 years now. Never have I ever heard of the insanity of something coming in on Optical S/PDIF and getting D/A converted internally except to exit from an analog output which is not the case here. That sounds like suspect hardware/software if that is really happening. How can a piece of software in a computer (binary - digital) convert a digital signal to analog then digital again and why on Earth would that be plausible ever? All analog audio must be A/D converted to use in a computer but digital audio stays digital until you play it out of an analog output.

Actually, Audacity being free and Windows being Windows this all makes sense :)

So again, keep this simple because it really is. LD Optical output>USB Optical device Input>USB cable>Host computer USB input>Audio Software. Set the software for 44.1KHz, 16 Bit, Stereo WAV file. That is the setting and there is no need to try anything else in this scenario. If the software has a selection for input source, choose the one for the (USB) capture device. If there is a selection for (word) clock source choose external or optical or USB, whatever they call the source input (the USB box). Do a 1 minute test. Depending on the software and your hardware you may not be able to monitor the digital audio in real time. When the recording is finished be sure to reset the (word) clock source to internal or you may run into sync issues when you playback.

The main issue, I suspect, is Windows and/or Audacity coupled with the lack of experience. Don't get discouraged - you'll figure it out eventually.


Unfortunately it's not that simple if one desires bit-perfect captures, since the audio could get internally converted to analog and then back to digital by the PC/input device, or otherwise altered so that it's no longer an exact digital copy.

The first posts on these threads on FanRes would probably be good starting points for making sure that you're recording the exact PCM data:
https://forum.fanres.com/thread-2742.html
https://forum.fanres.com/thread-2686.html


Knowing the hardware I have personally I know for sure my sampling rate is correct and also that that there is no D/A/D going on (I can’t even...that makes no sense to me).

Ok, that is something that actually makes sense why it isn't working then. Strange that something wouldn't accept the consumer standard sample rate of 44.1KHz. Anyway, move on. That M-Audio box is actually perfect for your application. Its cheap and has very humble requirements. It even will pass through AC3/DTS. I'd read up online about using it with whatever OS you're on. It may have some buggy limitation in Windows.

As for clock sync, read this: https://en.wikipedia.org/wiki/Word_clock So basically think of digital as a stream of info running at a certain speed (44,100 cycles per second in this case) controlled by a clock. When two different systems need to work together they need to decide who is the master clock signal. Usually it should be the source if you don't have a separate master clock source like many studios have. If you set the receiving end to be the master there is a chance you may have jitter or drop outs due to a clocking mismatch.

Now look at the setting/preferences in Audacity or whatever DAW you're using. I use a MOTU product that has a software panel that controls all that stuff. I just choose the clock source from a drop down menu. Your system will have be different so just look around.

In PCM capturing news someone responded to my post on Head Fi and mentioned this:

"Maybe the CM6206 can only handle 48k sample rates on S/PDIF? The data sheet says "S/PDIF I/O 48 KHz sampling rate" a couple of places. Laserdisc audio (including DTS) is at 44.1."

https://www.head-fi.org/threads/capturing-pcm-from-laserdisc.912747/#post-15137016

Interesting! So I might try the M-Audio transit when I can afford it.

All Faroudja and other video processors should be avoided. Faroudja shut down way before per pixel adaptive deinterlacing so none of the Faroudja stuff has decent processing per today’s standards.

Interesting you mention that. Here is a quote from the FLI2310 product brief from 2003 (used in the DVP-1080 from 2005/6):

http://pdf.datasheetcatalog.com/datasheet_pdf/genesis-microchip/FLI2310.pdf

DEINTERLACING –
• Per-pixel Motion Adaptive Deinterlacing
• Patented FilmMode Processing - Used for proper de-interlacing of 3:2 and 2:2 pulldown material.
• Edit Correction - Film content is continuously monitored for any break in sequence caused by “bad edits” and quickly compensates for the most effective reduction in artifacts.
• DCDiTM by Faroudja - Video is analyzed on a single pixel granularity to detect presence or absence of angled lines and edges, which are then processed to produce a smooth & natural looking image without visible artifacts or “jaggies”.

Not trying to be argumentative. Not trying to make blanket statements. Just looking for some clarification between some of the different products that are often discussed here and to learn from those who are knowledgable.

Thanks

Posted: 27 Dec 2019, 18:37 

Most Hollywood movies from the mid to late 1950s or early 1960s recorded all dialogue on set to mono analog 1/4" tape on a Nagra III then other Nagra models until around 1989 when Jeff Wexler (The Natural, ID4, Fight Club) first began using DAT to record dialogue on set.
First movie I did with DAT was "Ghost" in 1989 on a SONY D-10.
Prior to DAT those 1/4" tapes often got printed to a piece of film so they could edit and sync sound to picture. Then all the scoring and other audio gets recorded and mixed with the dialogue, likely to analog tape or maybe just a film print for distribution. Some videos below illustrate the process a little.

https://jwsoundgroup.net/index.php?/topic/29225-the-first-film-made-with-digitally-recorded-sound/
https://www.youtube.com/watch?time_continue=3&v=EgT4-gDaCNo&feature=emb_logo
https://www.youtube.com/watch?v=OjKQNykc_04&feature=emb_logo

In 1986 Sony introduced the D1 (component) digital video format and from then on "Digital Mastering" was possible. Prior to that it was likely 1" analog video tape. The D1 system allowed a SPDIF input so that the master contained digital audio. D2 (composite) arrived in 1988.

So technically speaking LD with a completely digital audio chain was not happening until 1989 at the very earliest and even then, Jeff was a Pioneer so it wasn't for another year or so before more mixers adopted that workflow. Even then, the DAT tapes *may* have just been transferred (via analog) to a piece of film as before the days of DAT because their systems had not evolved yet.

So, The Cotton Club in 1984 was almost certainly recorded to 1/4" analog tape (on set dialogue) so if the LD has PCM on it you should know that the source of the PCM is still analog.

Maybe some of that was useful....

Welcome to the club duderino.

Well, not all comedy but a good time is guaranteed for all.

A Classic: Wizard of Oz, The: The Ultimate Oz - Collector's Edition (1939) [ML103990]

Not that its stoner related but Dead Man is a great movie and a soundtrack that allows your mind to do all the work since there is little dialogue.

I'd also mention any classic animation like Looney Tunes, Disney (esp: Alice in Wonder Land & Fantasia), Winnie the Pooh...as well as things like Heavy Metal (1981) [74656]

Don't forget Pink Floyd's The Wall as well as their concert stuff like Pulse.

In that vein check this out:
Paul McCartney: Rupert & the Frog Song (1985) [PA-86-M037]

How about:
Kids (1995) (Uncut) [LDVM6311]

Also, personally I enjoy all the Nature and Space stuff from Lumivison especially IMAX features:
Ring of Fire (1991) [LVD9509]
Floating World, The (1989) [LVD9024]
To Fly (1976) [LVD9113]

The Mind's Eye series is a trip as well:
Gate to the Mind's Eye, The (1994) [ID2926MM]
Odyssey Into the Mind's Eye (1996) [MLV49877]

These are also pretty chill:
Anima Mundi (1992) [ID2609MM]

Posted: 15 Jun 2020, 17:45 

I'm not saying we should ban/censor. I'm not a book burner. Make art that makes people question their own reality - PLEASE!

My entire point was that if we as HUMANS move in a direction away from the formulaic and cliche'd stereotypes that are portrayed we might begin to see each other more as equals than we obviously do now. Did the Jazz Singer improve race relations or did it make them worse? Does that image have an impact today 100 years later? Sure does, though maybe not to YOU.

Jazz Singer vs Blazing Saddles. You can tell one is more serious than the other and with comedy you can begin to see how things like racism/sexism/homophobia are just so inherently unacceptable by the way they take things too far. Even the writers would probably agree that the characters they created are assholes and that is the point. You associate that behavior with assholes (like when people here say things like "China Virus"). Contrary to the Jazz Singer which was a serious drama that in fact celebrates a time when it was acceptable, even entertaining, to do blackface.

I just bought Fawlty Towers DVD set for my 77 year old father. I love all that stuff, especially Are You Being Served? I grew up watching Married With Children and All in the Family too. I GET IT. HA HA HA its funny, ok? I also grew up watching GWTW with my Mom because she really enjoyed it and I grew to enjoy it as well. Though, what I really enjoyed, was In Living Color . That show pushed back on all that racial stuff, gave it a new twist and a Black perspective and it was HILARIOUS. Some people at the time, however, thought it was racist against White people because they portrayed them and dumb prejudiced honkeys when in fact all they were doing was what other shows had already done for Black folks. They spoofed so hard on Anglo-American culture/media and its all genius. So there is my point again, there will be more shows that are produced/written and performed by non-whites and may be super critical of whites. I guarantee they will suffer a lot of criticism for being racist against while people. Just wait. Comedy has the ability to walk the line that drama doesn't, in my opinion.

I also watched the Rodney King beating and trial then watched my city burn to the ground. Now I'm seeing the same thing happen almost 30 years later. Nothing has changed but it needs to. I'm sorry if you disagree.

Again, some people here are very upset that SotS was never made available in the US beyond VHS. Disney decided to not promote the fantasy that slavery was not that bad anymore. Kudos to them. The government didn't force them to shelf it either. Those people are angry at the content creator/copyright holder for stealing their childhood away or whatever. "My heritage is being destroyed by the liberals!" I've never seen the movie and I could give a crap if is is or isn't released here (see how your personal experience can have an effect on being objective?). Keep pissing up a rope, waiving your flags and watching your VHS tape. Same with HBO and GWTW. When you own a media corporation you make the choice as to what is shown. Until then you get what you get. Sorry. Why don't you petition Disney/HBO and demand they give you the programming you deserve, lol. You should be proud to live in a democracy hahaha! Power to the people.

BTW I'm mixed race first generation American for whoever asked. My Dad is straight up R-A-C-I-S-T. That doesn't give me any more right than anyone else to say anything on anyone's behalf except mine. You can say whatever you want and I'll listen. I'm not some savior of the people or whatever. I just believe in listening to people and taking their concern to heart. Especially when a certain group has been systematically oppressed in this country. I, personally, think that is more important than people who aren't able to own SotS on 4K BR in the US in 2020.

I didn't start this topic. I'm just voicing an opinion as many here have and will continue to do so. I will continue to stand up for what I believe and don't have a problem confronting opposing opinions. That's how we grow. You do the same so hopefully we can meet in the middle and be civil, respectful, adult humans.

If this makes you uncomfortable you can ask to have this thread closed/removed/banned/censored or what have you ;)

Sheesh, people are the f'ing worst...and its only Monday!

You're welcome.

I paid ~$65 and had to wait 6 weeks for delivery from China. This is a distributor of OEM products made in China.

The specs are identical to DVDO's SINPRO power supplies. I bought one for a VP50 that was otherwise non-functional. This worked PERFECTLY and the plug fits nice and snug. The $6 power supply from amazon didn't work and didn't fit well.

Can someone please help me out? I'm humbly asking if anyone has the correct pin out of the original CWT PSM200A-89 power supply that shipped with the VPS-3800. It uses a 6 pin molex connector.

I ordered a replacement power supply but it has a 24 pin connector (standard for computers). I have the pin out for that but what I need to find out is the voltage and polarity of the 6 pin connection to the Crystalio. The CWT power supply lists the voltages and polarity on the label but does not indicate which wires/pins.

The 6 pin connection has Yellow, Red x2, Black x2 and Blue. I know it needs 3.3v, 5v and 12v.

I've sent an email to Lion@pixelmagicsystems.com as recommended by Substance. No response (no surprise). I have also sent a message to CWT through their website but won't hold my breath on them providing the info.

I'm not an expert by any means and I don't want to ruin the Crystalio or worse, start a fire. Based on another thread it seems someone was having issues and then a few months later the unit caught fire. I can't knowingly keep this thing plugged in especially considering the tragic fires we're having in California right now.

Kencol in October 2014 (https://forum.lddb.com/viewtopic.php?f=30&t=4601)
Hey guys, any ideas on where to source a new PSU for a crystalio 3800? My unit refused to turn on and was totally dead this evening and I'm guessing it's the PSU.

Kencol in August 2015 (https://forum.lddb.com/viewtopic.php?f=50&t=2972&start=40)
Finally got a hold of a replacement 3800 after mine caught fire!

I know that I need to short the "power on" pin to ground since this unit is "always on" which is part of the problem. I can solder and use a multi-meter but not too much more. I can probably figure out what is what but thought I'd ask here if someone has done it or could provide some useful tips or expertise.

I tried to ask for help/advice on one of the FB groups and got some snarky responses, please just scroll past this thread if that is all you have to contribute, thank you.

UPDATE:

Things are not always what they seem. I opened up the original PS again. I'll correct my earlier statement and say the board is somewhat labeled but is cramped and hard to see anything. Plus I'm not a pro so there is that.

PSinside1.jpg
PSinside2.jpg

Anyway, I tried to trace the wires to their sources and now understand why I was confused before.

For one, there was a ton of brown dookie that was used to hold the wires in place originally. I've heard this can become conductive over time. The 2 black and the yellow seemed to be connected to the same solder point but after meticulously cleaning the dookie away with 99% Alcohol I was able to see they are in fact separate. There were a few capacitors that also had the dookie of death surrounding them and so I cleaned all that away.

Remember how I said Yellow and Black were almost connected via the dookie? I'm guessing that was the main issue but I maintain that I know nothing.

I decided to just put humpty dumpty back together again and install it in the Crystalio and hope it didn't explode.

Prior to all of this my symptoms were a ever present chirp, like maybe from the fan I thought. This thing is always on so maybe the fan chirped and was nearing end of life. I've run it with the top open before and don't notice the fan coming on. So maybe the PS is overheating? Then it randomly powered off during a few movies but would work if I powered it back up until one movie it did it a few times too many and I decided to unplug it and investigate.

Now that I cleaned it all, re-installed it and powered it on......nothing. Well almost. It did power on normally but no input or output. The front panel buttons were also non-responsive. Sh!t.

Power down, check connections and unplug/replug the front panel connector.

Power up and bang, we are back in business! I'm running it with the top off and after about a half and hour I hear a little bit of the same chirping noise and the fan is not spinning at all...still quieter than before. The PS is hot to the touch but that's probably normal. I'm guessing that if it gets too hot it will shut down again. At that point I'll probably put in the replacement I bought.

I'm going to wait and see what happens with this for now but I do have a replacement and now I know what the C2 logic board wants (left to right looking at the mobo from the front):

Blue is -12v / Black are both 0v / Red are both +5v / Yellow is +12v

I really hope this has been or will be helpful to someone in the future. I also really hope the guy who was snarky to me reads this and re-evaluates his style of "helping people". What's the use of posting online so much an being a Laserdisc personality if you are only going to be an elitist jerk when people humbly ask for help? Communities are about supporting people and coming together as a team not joking about people's taste, skill-set or volume of acquired knowledge.

My LD-S2 would not eject at all when I bought it. The original grease had become quite sticky. I cleaned and replaced the old grease with fresh white lithium grease and have not had a problem since.

See the spots marked 2 in the attached image. I would just replace what you can easily get to in order to avoid any issues that might arise from further disassembly.

Thank you! Mine does the same. I'm in no rush to open this beast up but maybe if I get the courage to do the AC3 mod I can do both at the same time.

I love how we all share knowledge and help each other just to keep these things alive!

Next step is to find a new DVDO PSU, but I hear the eBay ones are not great for use and suffer early deaths?

That's correct the ones online are generally garbage. Sinpro was the one included with the DVDO. Astrodyne TDI makes the exact same OEM part. I bought one and can confirm it is 100% what you want. You need to call Britney:)

The problem is it looks like the connector is totally different to that required by the DVDO VP50 Pro?

One other thing, which took me back a bit. The bloke at Sinpro said due to safety certificates and standards even if they could make the old SPU45E-103 they wouldn't be allowed to import it to Europe for safety reasons. :wtf:

Anyone know of another PSU that would work and is safe?

The Astrodyne TDI is the direct replacement. It has the correct DC plug for the DVDO, not DIN....I doubt you'll find another OEM that makes this one due to the strange voltage/amperage.
