PCM1802 troubleshooting

doing some troubleshooting with my clockgen mod- just for clarification, it appears the board I have is a Type2, so the 3.3V needs to be fed to the right leg of the regulator. But, do I also need to run a separate bridge wire to the MODE0 pad on the bottom of the board? So basically it would look like one wire going to the 3.3V to the regulator; and another wire coming from the 3.3V to the MODE0 pad. Because with only the bridge to the regulator, there still isn't 3.3V going to the MODE0 pad.
I did not see this mentioned anywhere in the github/gitlab docs, so I'm unsure whether this (the absence of 3.3V going to MODE0) could be causing the distortion I've encountered.

clockgen baseband audio still distorted after alignment

cannot figure what I need to do to get the baseband audio processed correctly on a clockgen setup.
capturing video seems fine, but because I cannot get, nor set clockgen settings in powershell, I keep getting-

"'Exception: No devices found"

and

"cmdlet Set-CxadcClockGenRate at command pipeline position 1 Supply values for the following parameters: Path:"

when trying to set the output rate, and when

"Exception: Error initializing WinUSB: The handle is invalid."

So I'm beginning to think it has to do something with the clockgen rate being off before I invoke
LocalCapture.ps1 to do any capture.

Upon listening to the baseband audio (flac), it's noticeably distorted/garbled. I'm not referring to whitenose, but the actual video's audio sounding mistimed/pitchshifted/clipping. I tried everything that was suggested- using AutoAudioAlign via ld-analyze, manually aligning it in cli, etc. but nothing seems to fix the problem
Final decode and muxing still retains the distorted audio, even the file created after alignment

Requesting advice in getting this to properly work

Can SQPB VCR play svhs-et tapes?

I have vhs-c tapes that were recorded in SVHS-ET format. Does a vcr with SQPB can play them?

Perhaps the name of this forum should be changed?

I see more posts here from people who have absolutely no understanding of what the forum is about than from people who do. I don't know much about Reddit, I don't even know if it is possible to change the forum name, so I apologize if that is the case, and I apologize if this has been brought up and discussed before. I just think the name having VHS in it misleads a lot of people and clutters up the forum with a lot of questions that have absolutely nothing to do with RF capture. Also, RF capture is not just for VHS, it can be used on other tape (and video disc) formats as well, so an ideal name might reflect that.

MISRC GUI - A Universal GUI for FM RF Archival!

I and a couple other community members have been over these last few months, churning away at getting MISRC GUI in order, now this started all the way back in December right as an ear infection completely wiped me out and set back things drastically across the board.

Now before the MISRC v2.5 could be released, it clearly needed a GUI platform, this had to be completely platform universal in terms of operating system support band as if not more intuitive then the CLI but then it made clear sense to implement cross device support, so here we are today.

Now for anybody wondering, yes there is going to be a few little extra features added here and there that will only appear for certain devices but the overall functionality support is available for every device.

(For anyone wondering, machine control integration will be eventually added for consumer and professional decks, there's just a lot of little things to unify for that and there's a lot of testing involved.)

I will also make some side notes here that CXADC Windows support is yet to be fully tested, and offshoots of the standardised Clockgen Mod may not have audio support, but the DdD does have parity support with its original app, and of course full MISRC support for existing v1.5a users, HSDAOH audio support should be working but not every implementation is tested.

So go forth, play, tinker and break some things!

No signal from VCR with Domesday Duplicator

After flashing the DEO Nano and FX3 I connected the DdD and my computer recognizes it. The problem is when I connect it to the VCR via BNC to DuPont there is no signal at all. I’m using a SLV-N50 VCR. I’ve switched from 10 to 16 bit, connected the USB to a different port, switched to a different Sony VCR all to no avail.

I’m not sure if it is the BNC to DuPont cable, a Windows issue, or just faulty hardware but this is mentally draining. These parts are far from cheap and I’m wondering if I should’ve went the Clockgen mod, MISRC, or Hsdaoh route instead. Any input or advice would be greatly appreciated.

1987 VHS Tape Problem

Hello all, I am trying to digitize some VHS tapes of basketball games that were recorded in 1987. Most of them are fine but there is one game that I can HEAR the audio but it's just a blue screen when I play it back from a VCR. I tried it in two separate VCRs and got the same thing. The tape itself seems fine so I don't know what could have caused an issue with this particular game.

Does this sound like something that RF capture could possibly recover? If so, is there anyone with a setup in the USA who would be willing to check the tape out for me? I would certainly be happy to pay a fee for anyone who could check it out and possibly recover it. Thanks all.

Optimal setup for my use case

Hi all, I have a bunch of home videos that I want to digitize. Getting good quality is import to me to try to preserve an era of my life that will eventually be inaccessible in the future unless I do something about it.

I have a Sony slv -585hf. I opened it up last night and I’m fairly confident I’ll be able to tap in using DuPont connectors. I’ll check with an oscope this weekend.

  1. I assume for home videos there’s no benefit to tapping into the hifi audio correct?
  2. Will there be a noticeable difference in quality with a DdD vs a cx card?
  3. For line out audio I would just use rca and plug into the sound card correct?

Thanks for the help in advance. I have been kind of doing a deep dive the past couple of days on how to get this done so I could use a little direction.

Hi8 troubles: portion of video is gone, chroma is corrupted

Good morning. I have a problem with my Hi8 capture. When I plug it into the CX card, a portion of the video drops out on the camera display and it is dropped out on the luma on the RF capture as well. The rest of it has OK luma but corrupted chroma.

Is there something I am doing wrong? I've been able to capture VHS just fine so I don't think it's a software issue.

I used a CCD-TRV65 attached with flex cable to this board, soldered to a 10 microfarad ceramic capacitor and to a pigtail cable, which goes into the PC CX card. I don't use an amplifier. Could it just be a bad soldering job, or is there something bigger?

¿I-O Data GV-USB2 o Canopus ADVC-110 para digitalizar SOLO VHS?

Mensaje: ¡Hola! Quiero digitalizar exclusivamente cintas VHS y estoy entre la I-O Data GV-USB2 (USB, color 4:2:2 sin compresión) y la Canopus ADVC-110 (FireWire, formato DV 4:1:1). ¿Cuál da mejor calidad real de imagen hoy en día para VHS? ¿Vale la pena complicarse con FireWire por la Canopus o es superior la GV-USB2? ¡Gracias!
