Ok, so this quite a complicated issue I have been dealing with.
I have been testing my OSSC with my new Datapath VisionAV capture card and a 1-Chip SNES and RGB modded N64.
When I do SNES -> Scart cable -> OSSC -> BenQ RL2460HT monitor, everything works near perfectly.
When I use the capture card, I run into problems. I had previously used a Datapath VisionRGB PRO with an XRGB-2 Plus with ok results.
So I first started by connecting the N64 (with Mario Kart 64) -> luma sync scart cable -> OSSC -> VisionAV. I get a signal, but the image is very blurry and doesn’t look much better than composite.
I switch to the SNES -> CSYNC cable -> OSSC – > VisionAV, and if I do anything other than 2x mode, I get this:
Obviously, 2x mode isn’t going to cut it, so I tried multiple settings adjustments in the OSSC and had 0 luck.
I wanted to see if it was a sync issue, so I pulled out my XRGB-2 Plus and chained it between the SNES and OSSC. For the SNES, I get a great signal and picture (aside from the minor jitters the XRGB-2 is known to have) in the 480p 2x mode. 960p is perfectly acceptable for what I am doing. However, when I switch to the N64, I get a fantastic picture that truly looks RGB, but the signal keeps cutting in and out every few seconds.
I am really at a loss here. I have searched all over for answers and suggested settings, but can’t find a solution.April 26, 2018 at 1:48 AM #21137
I wanted to show it working on a monitor while simultaenously not working with the card. I ran the OSSC to one of the BenQs which has HDMI out and then ran that to the capture card.April 26, 2018 at 4:12 AM #21148
Well I just plugged in my PS2 slim (Street Fighter Anniversary Collection) via Scart and I dont get a picture either plugging it into my monitor or into the capture card. OSD shows no sync.April 26, 2018 at 5:14 AM #21149
I fixed the PS2 issue. Didn’t realize it doesn’t work with RGB. You have to set everything to YPbPr. Now back to the Snes/64 issuesApril 26, 2018 at 9:06 AM #21153BuckoA51Keymaster
Does putting OSSC into DVI mode make any difference?
PS2 works fine with RGB by the way, you just have to change the setting on the dashboard. For 480p you can use RGsB or component.April 26, 2018 at 2:15 PM #21165
No DVI mode does not make a difference.
I also keep getting inconsistent refresh rates with the SNES with the same game. Sometimes its 15.73khz 60.05hz. I turned it off over night and tried it this morning and got 15.74khz 60.08hz. It will work fine in 2x mode, but when I change it to any other mode, the video goes out. I can get up to 5x mode through the capture card for the N64, but its just so blurry.
When I chain it to my XRGB2-Plus (which seems to be the only solution right now), I get 31.46khz 60.05hz.
I have also tried switching out Scart cables from the CSYNC cable to the Luma Scart with no luck.April 26, 2018 at 4:09 PM #21168paulb_nlParticipant
The inconsistent refresh rates is normal. Can you post a capture of the blurry N64 in 5x mode?
I have a Datapath VisionRGB-E1 which accepts everything the OSSC throws at it.April 26, 2018 at 5:57 PM #21176
What are your ossc setting for the snes and n64 using the E1?April 26, 2018 at 7:11 PM #21180
This is at 720p60. Scanlines onApril 26, 2018 at 9:57 PM #21181paulb_nlParticipant
I am basically using default settings. For N64 de-blur you can use the 320×240 optimized settings http://junkerhq.net/xrgb/index.php?title=Optimal_timings. Adjust sampling phase until everything is sharp. For line5X de-blur you need to set the resolution to 1600×1200 or use 256×240 optimized mode otherwise you’ll get a black screen.
The image you posted is a heavily compressed and downscaled jpg. You should post a raw png capture. Imgur.com works well for that.
Here is a line4x capture of Majora’s mask:
This is line4x 320×240 optimized capture:

Ok another update. I copied the settings used by FBX in his SNES Optimal timings video and came up with an interesting issue.
When I follow his settings, the picture does not show up when Line4x is set to 256×240. It will show up in 4:3, but it does lose signal every 10 seconds or so.April 27, 2018 at 8:46 AM #21191BuckoA51Keymaster
May be that your capture card requires the SNES de-jitter mod to be fitted then.April 29, 2018 at 7:47 PM #21249
Another update. I received HD Retrovision cables for the SNES and still had the same issues, so it looks like the OSSC is just not friendly to the VisionAV. I received some E1’s and the SNES and OSSC work fine
