Ok, so I don't have a blank dvd to burn that file too, so I'm not able to test it. But I did notice that diagonal pattern on the blue screen when S-video is directly connected to the capture card. Do you think these noise problems could be caused by the camcorder instead of the cables? Like that's the one thing I haven't been able to test yet. I've exhausted all the s-video cables I have, and I can understand if a few are bad, but all of them? That just sucks.

It's possible. Try any other video source you have that has flat fields of color. You mentioned video game systems earlier.

Do you have any issues with what looks like video noise (diagonal lines) with your EVAL adv 7842 board? I capture ntsc laserdiscs, so I need the 3D comb filter turned on, but seem to get a somewhat noisy imagine. I built an enclosure for the board line with copper tape as well.

Hey clashradio! Ok so without the eval board, I'm getting this diagonal pattern noticeable on solid colors, like the blue screen of camcorders and vhs players. It was thanks to Vaporeon, I noticed it. A lot of that can usually be attributed to bad cables or bad capacitors in the device. The latter would suuck! I'm returning the camcorder, since it's within the 30 day and I don't wanna take the chance dealing with a bad unit. I might have to get another, or get a refurbished one serviced by a good technician.
Btw, any opinions on this doctorsony guy? I saw him on ebay and he says he's an old Sony technician. He was selling the model I wanted, for a huge premium, but if he serviced it good, and replaced any bad capacitors, I don't mind taking the hit. Thought I'd ask here.
Now with the eval board, there's apparently a rolling noise bar on solid colors. I haven't seen that too yet, mainly because I'm having trouble getting this damn eval board to work with my capture card. How did you get it working? Did you have to do anything special with the scripts? My capture card can't capture HDCP signals, and I think this board is outputting a HDCP signal which baffles me. It shouldn't. Sometimes it doesn't, and the capture card detects it, other times it does, which sucks.
So with my video game consoles, as you saw in the clip, they have their proprietary AV port on them. This means I can't use the s video cables I have, unless I use a female to male adapter, but that would just extend the already s-video signal coming out of the console. They would be a good test though. I can easily tell noise from video games because they're usually very clean. Hehe, video games are my expertise.
I wouldn't mind trying to replace the capacitors on my own, I've done it on my SNES, but I'm skittish around mechanical parts. I don't wanna mess them up, and while I don't mind dealing with video game consoles, with their non moving parts, things like VCRs and camcorders, with their electronic and mechanical components make me nervous. I'm studying computer engineering, not mechanical engineering damn it! Lol.
So if anyone has any good camcorder recommendations, hit me up! This is gonna have to go on hold for now, especially with classes starting up. -
The idea with the video game systems is to see if you can get a capture from any source without this noise, in the first place, not to test the S-Video cables you'd use with the cam.

I bought my board Jan of last year off eBay, as I could not buy it from any retailer, even the non-HDCP model which says in the documentation; page 26 of the 28 page manual "Professional version for non-HDCP encrypted applications. Purchaser is not required to be an HDCP adopter".
I haven't used the board prob since March of last year, so I'm pretty rusty. I used the program AvesBlue. Had better luck with this than Tera Term. I was working with Analog Devices support and they had me try a few things for the diagonal noise lines. I couldn't get them to go away totally, but one trick I did do was lower the overall Brightness of the file in my NLE. This seemed to help, as I was capturing via HDMI from the board to my cap card. It's sort of a quick and easy fix.
There is a device called Domesday Duplicator, which I'm going to try to figure out. It can cap from the raw RF signal on the laserdisc. I know you're not working with LD's, but I think they are in the process of the same concept with vcr's. -
Hmm, well I uploaded some video game clips using the SNES's s video cable. I'm not too confident about this s-video cable but the captures look ok. Final Fantasy VI is known for showing all sorts of noise inherent in the SNES. You might notice jailbars there. Otherwise, I couldn't find that diagonal pattern like from the camcorder, or the rolling noise wave.
Hey so clashradio when you did use the EVAL board, you were able to get an output from the hdmi port to your capture card? I don't know, it really doesn't wanna work for me. Whether I use the camcorder's s-video or composite video output, it just doesn't wanna output an image. The camcorder directly connected to the capture card works fine. -
Yes, I am able to capture from the HDMI output. I have an Osprery 827e video card which has digital and analog video/digital and analog audio inputs. I just got a new Win 10 PC built and am still testing all functions. HDMI cap is one I still have to do; will report back.
-
Hmm let me know how that HDMI capture goes with your EVAL board. I need to figure out why mine isn't working. Thanks man.
So I got this new monoprice cable and I recorded a short clip of the blue screen.I couldn't find that diagonal pattern noise like I saw before. I saw wavy lines, but that appears to be typical analog noise. No rolling lines either. Idk, it looks ok? I need to figure out that script that was posted earlier. Btw, this is a direct capture to my capture card, no eval board yet. That thing's still on fritz. -
Handful of us out there.

Diagonal lines / noise.
Code:4C 05 0F ; Enable Anti-Alias Filters on all ADCs ***
Using AJA Kona LHi for HDMI+audio capture. Hopefully your capture card is faithfully and losslessly capturing the HDMI feed.
I've made a cardinal sin doing all of my captures with automatic luma and chroma gain enabled... goes against Analog Devices recommendations - then again the docs recommend an incorrect pedestal config, so not sure if it was an error. I'd argue that home video and poor sources will have gain issues on their own and I'd like to at least clamp the signal and not get as much clipping - leave post processing for later. Does introduce another unpredictable error source though...Last edited by petet; 30th Jan 2020 at 19:30. Reason: S-VHS -> S-VIDEO

Hey!!! Petet! I was looking for you. It looked like you dropped off the face of the earth after November. Lol! It was your post that got me into taking a look at the EVAL board. Right now I'm having HDCP issues with it, no idea why. I bought it from Digikey. I'm trying to get all that sorted out. I used AVES3 and the provided scripts they had. Was using the S-Video 10 bit out.
Yeah, the Magewell Pro Capture can capture losslessly. I record using UTvideo at 422 to a second ssd. More than enough transfer speed.
So are you using their scripts at all, or doing everything manually? Do you mind posting your script if you're using your own personal one? Help a brother out. Lol.
Oversampling's always nice, it can get rid of a lot of noise. I remember for direct capture of SNES, if you don't do oversampling, you have to adjust the phase and stuff to get rid of a bunch of noise. This might be similar. With oversampling, you don't have to tinker with phase or hsync.
Man now I'm unsure if the camcorder is defective or if it was just missed settings. I had EDIT set to ON and TBC and DNR set to OFF. This way I could get the purest analog signal out of that camcorder as possible. -
Running through HDMI capture issues I've tried the following 'fixes' to get a capture running with the Kona:
1. Rerun script
2. Unplug/replug HDMI cables
3. Power cycle EVAL and/or capture system
4. Various orders of the above
I've since gotten rid of my Magewell and haven't used the latest firmware versions - does it not capture as well as you're expecting? I had some levels issues with it (appeared brighter than it should, gaps in histogram). I wish it would have done 24bit audio capture with no fiddly levels. Plug and play though, seemed solid.
Same, run my Hi8/VHS captures on edit with no TBC/DNR. Most of these operate at 8-bits or less in the digital domain (A->D->A) and I'm banking on 2011 chips are better than 199x chips.

Sweeeet! Thanks man. I'm gonna bum your script off you when I get the chance. Lol.
The Magewell's great, I have no issues with it. I mainly bought it for my video game captures from the OSSC. I needed a capture card that could handle a wide variety of non-standard signals.
Hmm...now I'm debating what I should do with that camcorder. I saw analog noise earlier, when connected directly to the capture card without the EVAL board. I don't know if it was the cables or the camcorder itself. I'm thinking capacitors if it was the camcorder. I've replaced capacitors in my SNES before, but I'm a little skeptical about opening up this camcorder and replacing its capacitors. Mainly because of its mechanical, moving parts. How did you get your camcorder? Which one did you get? Any issues? I got the CCD-TRV87 from Ebay. Seemed like a great deal, $87.00 I think.
Btw guys....anyone have any experience with this doctorsony person. He seems to fix sony camcorders and maybe has a good reputation? Idk. He's selling the same camcorder I got, but guarantees he fixed everything with it. Selling it for a pretty penny though, around $325.00. Ouch. Idk if I should return the one I got right now, and get that one or just deal with the one I got. I don't even know if it's defective or not. Decisions...decisions. -
As mentioned by others, test the capture with another stable source (dvd/blu-ray/game system/etc) with the same cables. You can also test to see what its like direct capture to PC with and without tape to see how much noise/loss is from tape write/read. You are also inside with low light, sensor is going to put off some noise - smart phones are miracles these days compared to shooting with old consumer analog systems.
Another option is to capture from another system to your Hi8, then capture that. That will eliminate sensor and show you quality of tape record and playback with your cables. -
The captures in post #37 are into the EVAL, correct? You said you had Manual Gain Control as part of your EVAL S-Video script, but there is an AGC effect every time the screen changes. Particularly egregious when it switches to full-screen white.
Full-screen red & especially full-screen green show chroma noise, also visible in the screenshot below.
Weird effects going on with these two patterns, though I don't have anything to compare them to. Why is there chroma around the grey parts of the grid?

The post #39 direct-to-Magewell camcorder Blue Back capture: luma looks good. Chroma looks about the same as the frame I showed in post #30. It's possible the "V" channel diagonal noise is caused by something other than the camcorder. A 240p Test Suite direct-to-Magewell capture may be useful for comparison.
[Attachment 51759 - Click to enlarge] -
Hey thanks Vaporeon for responding. Sooo...for the SNES, that was a direct capture to the magewell card without the EVAL board. Since that's on the fritz right now, I'm just testing direct captures at the moment. Now that SNES I was testing I had recently modded. It actually doesn't output s-video natively. I added 28 awg wires, connected directly to the encoder chip, and going to the AV pins for output. Now there is a point where the luma and chroma cross each other when going from the front side of the PCB to the bottom. Don't know if that could have an effect. So the only gain control for the SNES would be built into the capture card, or the SNES encoder chip, though that's ancient technology.
Hmm so that diagonal pattern was still present with the monoprice cables huh? Now, this is weird. Man I hope it's not a capacitor issue in the camcorder! I can fix it...I just don't want to. Lol. I have the tools. It's mainly the mechanical parts. I always get skittish around those.
So yeah 240p test suite was direct to magewell, no eval board in the way.
Now I wouldn't be surprised about those SNES s-video cables. They're not particularly high quality. Think I got them on ebay. They're about 6 feet. I'd have to scour the retro game forums for some high quality cables, but I use RGB for my old consoles, so I haven't really bothered.
So petet, do you mean test the camcorder, connected to the magewell, without a tape? You know if I try that I get no signal in VTR mode. I have to have a tape and press play to actually get signal. Camera mode gives me signal regardless, but I can't get a solid blue screen from that. It sucks. If you mean just use a dvd player, I gotta buy some blank DVDs. My local grocery store should have some for cheap.
I might just end up keeping the camcorder. It's in good cosmetic condition and I'm hoping it's not the capacitors that are faulty. I have no frame of reference for these camcorders though. Did they have failing capacitor issues? It's the CCD-TRV87. Made in 1999 I think. 21 years old. My SNES capacitors were in better condition, but I replaced those anyway, and that console was from 1995.
Hmm so even my SNES shows chroma noise. Maybe it's not a camcorder issue then. Something is causing chroma to bleed into places where it shouldn't. Capture card? That would suuuck! Though I do plan to use EVAL board for my final captures anyway. And vaporeon, I don't think you noticed chroma noise when connected to the eval board. Just luma rolling noise I think?
Edit: Btw guys, I just wanted to say thank you for all the help. I really appreciate it. I am such a video noob and I mainly record PC video games, and even that's rare. But petet, vaporeon, thanks.Last edited by TheDrifter363; 1st Feb 2020 at 16:43. Reason: Saying thanks
