JVC - HM-DR10000EU does not detect DV input from ADCV-100

[SF01]

Greetings.

I recentely acquired an ADCV-100 hoping it could pass through the DV signal from PC to another DV device, namely JVC - HM-DR10000EU.
And while ADVC-100 generally works, accepts analog input and converts it to DV output, accepts DV input and coverts it to analog output, I haven't been able to fully utilise the FireWire passthrough option.

It does however transport the DV signal from an HDV deck to ADVC, displays the analog output, but SCLive only detects the DV signal when the HDV deck is selected, completely bypassing the ADVC, when ADVC is selected as input it displays an error code 137.

Outputting DV signal in Vegas results in analog output being visible, but neither HDV nor D-VHS deck can properly accept it and does not output analog signal to monitor. Outputting the DV signal in SCLive only works when HDV deck is selected and once again the ADVC is bypassed and does not even produce analog output. Strangely Playback to ADVC does not work, but when playing a clip on the timeline the ADVC gets the image and displays it through analog output, but does not pass through the DV signal to other devices.

I have tried switching DIP 6 to both ON and OFF positions.

The D-VHS deck accepts DV signal from the HDV deck as input and properly outputs them through analog outputs for monitoring.

But the entire purpose I got ADVC was to use the DV passthrough to D-VHS deck, since Vegas does not detect D-VHS deck as a DV device to send DV signal directly, so I thought It could send it to ADVC, which it can, and ADVC would just pass the signal to D-VHS deck for recording, but it appears that it doesn't really do that, with HDV deck it acts like it wasn't there, the PC detects the deck and signal, as if it was directly connected, but when switching to ADVC SCLive refuses to connect to it to get the DV input from ADVC coming to it externally.

Just for thoroughness, I have excluded the PC from the equation and connected the HDV deck to the 4-pin front DV connector and the D-VHS to the back 6-pin connector and played the tape from HDV deck and he D-VHS received a DV input, I checked analog output on all three stages and is there, then reversed the FireWire connections and it also still worked fine.

Are there any options I could try to utilise DV to DV passthrough when connected to PC?

The HM-DR10000 apparently does have DV input, but not DV output. The firewire ports on the back are probably for the MPEG2 stream output which regular DV devices will not understand.

I'm also not sure what you mean by HDV deck - HDV is a different format altogether that can also be sent over firewire, but standard DV devices are unlikely to recognize it. HDVsplit application on computer will accept it. Some HDV decks can still play regular DV tapes and output regular DV though, so it would be helpful to be more specific about what the settings and models of these decks are - maybe even a picture of how you have things connected or listed as a chain in a single line.

PAL version of DR10000 only has DV input, no digital output whatsoever and no MPEG2 input.
By HDV deck I mean HVR-M15E specifically, not HDV video, this is why I always refered to the signal as DV.
PC->FW->ADVC->FW->D-VHS = no image at the D-VHS end with input selected as I-Link.
PC->FW->ADVC->FW->HDV = no image at the HDV end with input selected as HDV/DV.
HDV->FW->D-VHS = image from tape
HDV->->FW->ADVC->FW->D-VHS = image from tape
What I require is a tapeless workflow from PC to D-VHS through the DV pipeline.

Hmm, that is a unique application indeed.

Are you actually recording onto D-VHS tapes in the D-VHS format, or is it just a D-VHS deck recording as either S-VHS or regular VHS? What other inputs on the machine do you have available and have those been tested as working? Depending on your application, you might be able to get a lot better results by not using DV as the input. D-VHS supports a few different resolutions, so would be good to know what resolution you'd be recording at if using D-VHS.

It may be possible to connect it to a Sony MicroMV camcorder, since that format is also standard-definition MPEG2 video over DV (FireWire). In fact, DVHSCap is one of the programs you can use to capture video from a MicroMV camcorder.

Yes, I need to record D-VHS, so DV input avoids the analogue gap quality degradation.
For regular S-VHS and VHS analog inputs work fine.
Actually the device does not have an internal converter to transform DV input into analog signal for recording, there is an error code for than when attempted.
NTSC D-VHS supports different resolutions, not PAL, it's stuck with SD.

The ADVC is strictly a DV device, it will not work with MPEG2, same with the DV input on the PAL D-VHS deck, it only accepts DV, not mpeg, I have already tried with the same workflow I use for NTSC D-VHS which works flawlessly with both CAPdvhs and dvhstool.

I am yet to acquire a microMV.

Fair enough, but still kind of curious why one would make a new DVHS recording these days, like what is the use case? Knowing the use case might give some ideas about how to get better quality out of the final result.

DV is similarly specced to the sort of MPEG2 TS that DVHS would use, but they use different compression - intraframe vs intraframe, so I kind of feel there's a potential to sort of clash with each other resulting in possibly stacked compression artifacts when going from one to another in realtime, even if it is all digital.

I would bet you'd get better results out of a Blackmagic Monitor 3G device (outputs 4:4:4 SD SDI from just the active window of a Davinci timeline) and then convert that to S-Video with something like the Brighteye 11 which converts to composite, S-Video, and/or Component video at 12 bit color.

I have a VHS label and for one release I wanted to make a special edition few copies of S-VHS, D-VHS, DV, Video8, Hi8, and Digital8 tapes alongside regular VHS. Some of the formats are already gone. I can do NTSC FullHD D-VHS no problem, but the problem is getting pure DV signal to PAL D-VHS input. I have tested the recording with miniDV to D-VHS and it didn't have visible artifacts, the DV masters and tapes also look very neat.

Ah. If the actual master for the video is DV, that makes more sense. I was figuring you were using DV as more of an intermediate format for something that was originally HD or analog, but seems neither is the case knowing that.

If you're releasing Digital8 versions from the master, you're essentially also providing the master since the Digital8 version (which is DV) should be identical to your master, not a whole lot different than sending out a flash drive with the DV file on it, but requires a Digital8 player.

I still think most DVHS decks can only record a digital source from the MPEG2TS input (via firewire), but if your recording deck does not have a MPEG2 TS input, I'm not sure what else to recommend other than using a high quality analog input as an intermediate if you don't want to get a deck that does have that input.

I have decks that have MPEG input, but they are NTSC. PAL decks only had DV input and no digital output.
Yes, theoretically D8 and DV cassettes should be a lossless copy, but read errors do happens plus the lengths and contents are different. I would have to make a separate 276 minute long DV tape master to transfer to a 240 minute D-VHS.
