Looking for cable/adaptor for DVDO iScan Pro
I need a DE-15 male to 3xRCA male (YPbPr) adapter or cable for the DVDO iScan Pro so that I can take the YPbPr signal from the DE-15 port and plug it into an OSSC or RetroTINK 5X Pro's 3xRCA YPbPr input.
Does anyone know if this cable's wiring matches the DVDO iScan Pro's YPbPr pinout?:
https://www.monoprice.com/product?p_id=2409
Or if anyone has any other recommendations. The safe length I need is 26 inches but the cable I end up with can be slightly shorter or longer and I'm sure it will be fine. However, the linked cable is 10 inches over so if there is a shorter option of course that would be better since my setup already involves other analog cables in the chain, and keeping everything as short as possible would be great! Thank you

Re: Looking for cable/adaptor for DVDO iScan Pro
the OSSC can accept YPbPr on it's DE-15 though...can't the RetroTINK 5x Pro? If so, just use a VGA cable and set your output as you want it on the DVDO side...
unless you really need the LPF for your sources...The AV3 input is a VGA/HD-15 connector which supports video in RGBHV, RGBS (pin 13), RGsB and YPbPr formats.

Re: Looking for cable/adaptor for DVDO iScan Pro
The RT5X doesn't have a DE-15 input, but you know what I just realized that I wouldn't be sending the RT5X a signal from the DVDO anyway since the RT5X has all those deinterlacing options. So I would only need to send it to the OSSC, so in that case if the OSSC can accept YPbPr through the DE-15 input then I might as well get a standard DE-15 male-to-male cable and use it to transmit the YPbPr from the DVDO to the OSSC. Thanks!
But just to make sure before I buy the cable, you are totally sure that the OSSC can accept YPbPr through its DE-15 input?

Re: Looking for cable/adaptor for DVDO iScan Pro
yes, it absolutely does. But as said, you're missing the LPF option that you get when you're using the "proper" component input instead.
And regarding your cable question: Component through HD15 uses the regular RGB pins, so any breakout cable you can find (including the monoprice ones) will be fine.

If this is what you need it should be relatively easy to add one with something like this https://etim.net.au/shop/shop.php?crn=2 ... how_detailRdCrestdBreegull wrote:The RT5X doesn't have a DE-15 input
Re: Looking for cable/adaptor for DVDO iScan Pro
FYI: For connecting an iScan Pro to an OSSC, you can leave both machines in RGBHV mode just as well. Why bother with component?
And the same is true for pairing an iScan Pro with a 5X. For this you just need a HD15 to Scart sync combiner board (Bob was teasing these recently and they should be available soon). Again this would leave the iScan in RGBHV output mode.

Re: Looking for cable/adaptor for DVDO iScan Pro
I think the only 480i sources I'd be sending the iScan Pro would be from GameCube and PlayStation 2 which would both be sending component YPbPr via 3xRCA male. Are you saying if that switch on the iScan Pro is toggled to RGB rather than YPbPr that it will actually transcode the [480i] YPbPr signal it gets and output it as [480p] RGBHV?Fudoh wrote:FYI: For connecting an iScan Pro to an OSSC, you can leave both machines in RGBHV mode just as well.

So if true then it comes down to two options:
-DE-15 male to 3xRCA male, for transmitting 480p YPbPr from the iScan Pro to the OSSC, having benefits of a low-pass filter
-DE-15 male to DE-15 male, for transmitting 480p RGBHV from the iScan Pro to the OSSC, without LPF benefits
Is that correct? Which would be the better option for GameCube and PlayStation 2? And btw this is all for the purpose of capturing 480i games from those consoles as a very high quality deinterlaced image through my computer's capture card (using an AVerMedia Live Gamer BOLT capture device to my iMac and using OBS).
Re: Looking for cable/adaptor for DVDO iScan Pro
yes. I always considered RGBHV to by the primary output format on those early line doublers. After all it was was all CRT projectors expected to receive.Are you saying if that switch on the iScan Pro is toggled to RGB rather than YPbPr that it will actually transcode the [480i] YPbPr signal it gets and output it as [480p] RGBHV?
The iScan already uses a pretty heavy LPF on its input, so you most likely don't need the additional LPF.
Both options are valid. For the OSSC you can try both. Component output on the iScan Pro is more interesting if you want to pair it with the 5X, since this way you don't have to bother with the sync combiner.
do you already have a 5X ?And btw this is all for the purpose of capturing 480i games from those consoles as a very high quality deinterlaced image through my computer's capture card (using an AVerMedia Live Gamer BOLT capture device to my iMac and using OBS).
While the iScan has a proper film mode, which the 5X does not, it's video deinterlacing isn't great. It's looks good because it does heavy filtering, but the level of perceived detail during motion is likely considerably higher on the 5X than on the iScan. That's just the 20 years between the iScan's SiI503 and the motion adaptive deinterlacing Mike did on the FPGA.

Re: Looking for cable/adaptor for DVDO iScan Pro
I do have an RT5X.
So this is the interlaced content I'll be capturing, looking to find the highest "archival quality" possible:
-Game consoles running in YPbPr 480i, mostly the GameCube and PlayStation 2
-VHS tapes running in CVBS 480i
These are the options I was going to test VHS capture with, and then compare them to see which gives a more accurate archival capture:
-VHS output via HDMI from my Panasonic Blu-ray/VCR combo player
-VHS output via YPbPr from the combo player into the RT5X, trying out the different deinterlacing modes
-VHS output via YPbPr into the DVD iScan Pro, output to the OSSC
-VHS output via CVBS from the combo player into the RT5X, trying out the different deinterlacing modes
-VHS output via CVBS into the DVD iScan Pro, output to the OSSC
I suspect there will be zero difference between outputting CVBS and YPbPr from the combo player since VHS is CVBS native. I am also guessing that using the iScan/OSSC or RT5X will give better results than outputting VHS from the player via HDMI since the latter would be using the player's deinterlacing which I suspect was just made to "get the job done" rather than to deliver amazing deinterlacing performance.

Re: Looking for cable/adaptor for DVDO iScan Pro
Nope. VHS, like all "color under" tape formats, is natively Y/C S-video at the media level. You're probably thinking of Laserdisc, which is indeed CVBS at the source.RdCrestdBreegull wrote: VHS is CVBS native
If you're willing to throw money at the problem, a newer S-VHS/ED-Beta/Hi8 deck running S-video into a BrightEyes TBC (model 1, 3, or 75) and SDI capture capture card is probably the best option these days. Audio via a quality interface like a Motu or RME. Then use VirtualDub2 to put all that into a 10-bit 4:2:2 lossless/intermediate codec with PCM audio. Clean up everything in post and call it good.RdCrestdBreegull wrote:see which gives a more accurate archival capture
Would the RetroTINK 5X-Pro be the best 8-bit color ADC out there for reasonable money these days? A better analog front-end than any of the legacy DVDO stuff?

Re: Looking for cable/adaptor for DVDO iScan Pro
Eh unfortunately I'm going to have to stick with the options I listed for VHS capture. So then if VHS is natively Y/C should I be outputting it via the component YPbPr 3xRCA from my combo player? (since I don't think there is an S-video output) And which of the options I listed do you think would be best? Seems like we might not know if using the RT5X or the DVDO iScan Pro would give better results?

Re: Looking for cable/adaptor for DVDO iScan Pro
Go ahead and try the S-video outputs of the combo player as the S-video probably works with VHS. Most of those DVD+VHS combo players had functional Y/C from VHS on anything above the absolute cheapest playback-only versions. Some late, high-end Blu-ray + VHS models did, supposedly, support VHS out over YPbPr.RdCrestdBreegull wrote:So then if VHS is natively Y/C should I be outputting it via the component YPbPr 3xRCA from my combo player?

Basically all the shortcomings pointed out in that video regarding the 2X were fixed by the 5X, plus using the 5X's HDMI output would avoid an extra analog<->digital conversion cycle capture-side.
It's the later big boy DVDO boxes like the VP50 Pro / Edge / Duo that people think of for deinterlacing and scaling performance (though the regular VP50 or VP20/VP30 with ABT102 card should have identical interlaced SD handling). On paper the big box DVDOs should still beat the 5X for reasons like a 10-bit YUV color pipeline without extra RGB conversions or being knocked down to 8-bit like the 5X, but it would be interesting to see a head-to-head. Benchmarking the audio ADC performance of these would be interesting too as I don't think anybody has ever done that.
That said, however, for doing archival work you'll want to capture the raw interlaced 480i/576i and do your processing in post for much better results. Less is more here on the front-end. If your tape deck and tapes are in good mechanical condition, you can probably even get away with just a IO Data GV-USB2, which is arguably the best of the cheap SD capture dongles.

Re: Looking for cable/adaptor for DVDO iScan Pro
It's weird because I got the DVDO iScan Pro just for interlaced content because MyLifeInGaming would always talk about it, but now you're saying even the RT2X does a better job...
My combo player only outputs VHS via CVBS, YPbPr, or HDMI. It does not have an S-video output.
Are you saying it's actually better to deinterlace the footage on my computer? But any footage I capture will be deinterlaced already (crappily) since for example outputting VHS via HDMI from my player means the player is deinterlacing, or capturing CVBS from my player on a capture device with CVBS input would mean the capture device is deinterlacing... So what do you mean by capturing the raw 480i footage, wouldn't that be impossible unless I captured via bob-deinterlace?

Re: Looking for cable/adaptor for DVDO iScan Pro
Link on the raving by the MyLifeInGaming guys? The DVDOs people usually rave about are a decade newer and with the ABT102 chip, rather the iScan Pro, which is pushing 20+ years old at this point. Only thing I'm aware of from that era that people still rave about are the Faroudja stuff.RdCrestdBreegull wrote:It's weird because I got the DVDO iScan Pro just for interlaced content because MyLifeInGaming would always talk about it, but now you're saying even the RT2X does a better job...
Per Fudoh on the SiI504 (which is newer than the SiI503/DV103 in the iScan Pro):
"The old Lumagens are SiI504 based, just like the DVDOs. Solid film mode, mediocre video mode, not the greatest filtering."
For pixel art the 2X would win (as outlined in that video), but has issues with the instability of VHS. 20 year old DVDO vs the 5X's motion adaptive deinterlacing would definitely favor the more modern hardware if you're watching things real-time.
What's the exact model? Will it allow you to set 480i/576i out over component and/or HDMI (HDMI is almost certainly no on 15 khz...)? Does the VHS video look notably better over YbpPr vs CVBS?RdCrestdBreegull wrote: My combo player only outputs VHS via CVBS, YPbPr, or HDMI. It does not have an S-video output.
Yes. Since you aren't watching things in real time, you can throw all the time in the world and effectively unlimited compute resources at making the deinterlacing look good.RdCrestdBreegull wrote: Are you saying it's actually better to deinterlace the footage on my computer?
Some torture test examples on modern offline deinterlacing:

https://www.youtube.com/watch?v=ErD75pT8soA
https://www.youtube.com/watch?v=XwK0Hu8dRR8
That's why I'm saying you should see if you can get the original interlaced format out from component/S-video and seeing of component looks notably better than composite on your unit. You want to do this for an external scaler anyways, regardless of video capture.RdCrestdBreegull wrote: But any footage I capture will be deinterlaced already (crappily) since for example outputting VHS via HDMI from my player means the player is deinterlacing, or capturing CVBS from my player on a capture device with CVBS input would mean the capture device is deinterlacing...

Re: Looking for cable/adaptor for DVDO iScan Pro
So if I end up using the YPbPr output from my player, which scaler would I feed it into? My capture card is an AVerMedia Live Gamer Bolt.
Re: Looking for cable/adaptor for DVDO iScan Pro
My best guess is that the iScan would look better due to it's more agressive filtering, even though the 5X is technically the better deinterlacer for video material.

Re: Looking for cable/adaptor for DVDO iScan Pro
So my Panasonic DMP-BD70V Blu-ray / VHS combo player can only output 480p and up via HDMI. It can output 480i from YPbPr and CVBS, but I don't know how to actually capture that 480i video since I would need to hook it up to an ADC in order to get the video into my AVerMedia Live Gamer BOLT capture device. I currently have the player connected via YPbPr to my RetroTINK 5X, but the RT5X cannot output 480i via HDMI, only 240p and 480p and up. So how can I get the 480i interlaced video from the VHS tape, so that I can deinterlace in post? For scalers I also own an OSSC but I don't think that can output 480i via HDMI either.
I could always just send the YPbPr to the RT5X and apply deinterlacing, and output and capture it in 1080p, but it would be better to capture it as 480i somehow so that I have that master 480i footage to use more advanced deinterlacing programs with.
edit: So I did some VHS capture with the RetroTINK 5X and these were some of the settings I used:

I messed around with the different deinterlacing settings and Blend was the only one that didn't have combing artifacts on the edges of things. Would've been nice to capture in 480i and then apply deinterlacing in post but I just couldn't figure out how to capture in anything other than 480p and above. So yea I just had the player sending the RT5X a 480i signal and then applied Blend deinterlacing and output it as 1080p into my capture device.

Re: Looking for cable/adaptor for DVDO iScan Pro
You can get a very cheap YPbPr to HDMI converter without deinterlacing.
You have to pay proper attention to the codec you're using! Almost all compression codes are configured for frame based encoding these days. If you apply that to interlaced content while color subsampling is applied, then you get visible crosstalk between the fields. It's important to avoid that. Frame based codecs or codec settings will treat two weaved fields as a single frame and apply compression to that.

Re: Looking for cable/adaptor for DVDO iScan Pro
This is the YPbPr-to-HDMI converter that's recommended by RetroRGB: https://www.amazon.com/dp/B003VJ9RP6
Will that work, and keep the signal as 480i? Then can I capture as 480i to my AVerMedia Live Gamer BOLT capture device?
How do I tell what codec I'm using?
Here are clips of one of the VHS tapes I captured using the above settings I mentioned:

Re: Looking for cable/adaptor for DVDO iScan Pro
The converter should be fine.
Your BOLT is a thunderbolt device, right ? Should have the bandwith to deliver uncompressed 4:4:4 to the PC, so it's just a matter of choosing the right codec in your capture app. What do you usually capture to ?
The capture samples look quite solid, especially in terms of noise. But I can see the "blend" deinterlacing here and there.

Re: Looking for cable/adaptor for DVDO iScan Pro
I just ordered the analog YPbPr to HDMI converter. I got the one without upscaling since I need it to output 480i, as opposed to the more expensive one with upscaling that would output 720p or 1080p. Yes my AVerMedia device is Thunderbolt. What's this about codecs?
Re: Looking for cable/adaptor for DVDO iScan Pro
Only a small handful of codes today can properly be configured for interlaced encoding.
This does especially matter if you're using a codec that reduces the vertical color resolution within each frame, since the codec will then mix two fields that might not match and run a color compression over what it assumes to be a full frame.
To avoid the problem completely it's best to capture into a 4:4:4 codec with full color resolution first and only compress into a 4:2:0 codec after you've done the deinterlacing (or apply a codec knows how to handle interlaced content in case you want to keep the material at 480i).
