OSSC (DIY video digitizer & scandoubler)

[NormalFish]

So is there a capture card that people would recommend for high compatibility with the OSSC (among high quality/low lag/whatever other features people enjoy in a capture card)? The threads here on capture cards are helpful but I'm struggling to figure out which offers me what I need (high OSSC compatibility).

[P1kas]

I think that depends. Do you just want to capture the OSSC output? I think any of the usual HDMI capture cards with RCA audio inputs would work. Elgato Game Capture HD being one of these.

If you want to capture before the OSSC, then you'd probably want a USB3HDCAP/Micomsoft X-Capture 1 for USB versions, or PEXHDCAP2/PEXHDCAP60L for PCIE versions. These cards all capture 240p RGB/component so they should work for most important sources.

Splitters would probably be necessary if you're capturing before the OSSC, depending on what capture card you get

[NormalFish]

Well I've got an avermedia 1080p30/720p60 card with VGA and HDMI inputs. Haven't gotten aroung to testing it extensively with the OSSC, though, since i don't have the proper adapters and splitters and such. I'm somewhat skeptical it will work, though, since even with the framemeister's 720p output it gave me hell on a regular basis.

I'd like to capture the OSSC's output. Capturing it before would make my set up a bit ridiculous. I have audio going in to my computer by means of a mixer, so no need for audio integration.

[P1kas]

Unfortunately, I can't give much advice as to which capture device would be best because I'm not in a position to test them all. Definitely try out your avermedia, and see how that works. Others whom have tried can probably give better input

here are some Super Nintendo and Sony PSP shots (display is Asus VW246h, processor is vp50pro, output resolution is 1080p, image enhancements are, EE-100, DE-10, color saturation+45 and screen zoom for the PSP, so that the image fills the entire screen)

[BuckoA51]

Those PSP shots don't look too bad at all. I could do with picking up a PSP Go for some big screen PSP action.

[Blair]

yeah the PSP has lots of great games, I personally think the vast majority of them look and play better on a big-screen TV/monitor rather than on that tiny little LCD (with the exception of vita, I think most of the handheld gaming systems have terrible screens).

the only downside when using the OSSC+PSP is that it's scanline pattern doesn't work correctly. a custom PSP scanline pattern would have to be implemented in a future OSSC firmware update (but only if there's enough demand/time and resources). would be awesome for titles like, Street Fighter Alpha Three MAX, Valkyrie Profile: Lenneth, And Final Fantasy Tactics: War of the Lions.

[ZellSF]

I figured out the video artifacts wouldn't filter OSSC (but the XRGB-mini would) on my Turbo Duo, it was a inadequate PSU. Somehow making the entire system work but introducing really subtle video distortion.

[Xyga]

EE-100

Wow, though I understand why I think it's better around -70 or -80.
In my eyes this is the lower threshold, where it goes from 'smooth' to 'blurry'.

[Blair]

yeah that was a bit on the high side (although I think the images still look pretty darn sharp), but I was interested in seeing what would happen to the scanlines and if I can get the colors to bleed a little bit (only seems to work on red).

more of a test than a final recipe, especially since I haven't even had time to test all of the pixel perfect settings from the wiki (anyone taken some good comparison screenshots of those yet?)

side question: how are the OSSC scanline patterns generated? is it based on the input resolution of the game? or the output resolution of the OSSC? is it a set stock pattern every time?

Nothing in particular to add to the discussion here just yet, but I just wanted to congratulate Marqs again for all his work on this project. I got my DIY kit put together a few weeks ago and have been playing around with how best to arrange things. My collection of compatible consoles is still a bit thin, and I certainly don't have any kind of fancy capture device, but here are the results I've put together so far:

Hi guys !!
Just watching the jarp's amiga screen, and I wanted to test his settings

So here are mine mixed with his :

Setting used : (pal Amiga 1200)
pal 288p > line X3 > sample rate (not remeber clearly between 200 and 250)
H. backporch: 198
V. backporch: 24
H. synclen: 72

https://www.youtube.com/watch?v=dcoGaHzgLAg

The video shows the ossc vs my 19" jvc (equal to sony bvm)

Maybe ossc's scanlines are a little too strong (100%)

The colours are coming and going, but that's my amiga fault (maybe have to change capacitor, like said earlier in this tread), this thing is not visible so much with the crt


ps : trying to capture my Eizo crt 31Khz when I'll got time

[neorichieb1971]

OSSC request please.


Can someone put some Saturn/PS1 Parodius screen grabs up please? Its what I use to benchmark colors with 240p on the big screen.

Can someone also show me Mr Driller VGA on Dreamcast?


Thanks very muchos.

Finally decided to connect my OSSC + DVDO Edge setup to my Intensity Pro for direct capture. I was playing Final Fantasy Tactics because (1) that game has the smallest text I know of, and (2) I wanted to see how the PSP War of the Lions remake compares in sharpness on a PSTV and on a PSPgo through component zoomed in with the DVDO Edge, with or without the OSSC's line X2 mode.

First, FFT on a PS1 (SCPH-5501), RGB SCART, line X3:


FFT: WotL on a PSTV in 720p with maximum zoom:


FFT: WotL on a PSPgo through component, zoomed in with a DVDO Edge (no OSSC), upscaling from 480p to 720p:


FFT: WotL on a PSPgo through component, with OSSC line X2, then zoomed in with a DVDO Edge, downscaling from 1440x960p to 720p:


I made more comparison pictures and you can download them here.

FFT: WotL on the PSPgo was zoomed in for both tests with the same DVDO Edge settings (V1.727x, H1.475x). Note that the OSSC pushes the picture down a bit. Also I probably could've zoomed in more, but if I'm uploading videos I'll be cropping and resizing anyway. And, well, I don't quite trust the PSTV's aspect ratio since there should've been very, very slight pillarboxing at full zoom, but that's another topic...

I also noticed that whenever I capture from PS1 games I'd have to set my Intensity Pro to capture at exactly 720p60 Hz instead of 720p59.94 Hz like I do for everything else. Didn't matter if it was a PS1 (SCPH-5501) running RGB SCART in line X3 mode or a PSPgo playing a PSone Classic in 480p through component in line X2 mode.

Since everyone probably has different solutions for zooming in PSP games, I don't know how scanlines are going to work for PSP games (aside from having our scalers output 480p after all that other scaling and adding an HDfury & an additional scanline generator...), but I think the OSSC's line X2 was absolutely the cure for the blurriness of a zoomed in PSP at 480p. I thought we all wanted razor-sharp pixels!

[headlesshobbs]

Does anyone still have their SLG3000 handy?

I just noticed that when pairing this up using it's double on or off settings, I can somehow replicate the 15khz flicker that you normally see when running a crt display. Also running scanlines on 480i content tends to do the same thing.

I may want to set this up later to see if I can get my light gun to work with this.

Has anyone else has issues with RGBHV input and the Dreamcast? Not sure if something has started failing in my unit, but the other day I noticed that there is a random flicker/white level change happening with VGA input from my Dreamcast. Noticeable on primarily lighter colors, especially the boot sequence. None of the other inputs have this occur or even with RGBS over AV3. Tried swapping Dreamcast systems, power supplies for the OSSC and it still happens. Bypassing the OSSC doesn't show this issues on my VGA monitor. I'm going to try another RGBHV source like my GCN or my Xbox 360 VGA cable tonight to see if it's that or something weird with how my Dreamcast VGA box interacts with the OSSC.

I have experienced flicker and color issues with this cable:



I first thought it was an ossc issue, but I pulled out my old vga box



Any while the Naki fixes the flicker there is still some color issues but less than before. Mostly noticeable only on solid black backgrounds with logos.


So your VGA box might be the problem.

Hmm, the one thing making me think it might be the OSSC is that the Dreamcast's color stability is perfect when I connect directly to my VGA monitor (my DC VGA box is a Performance VGA box), its only when using the OSSC w/ active VGA converter that I see the problem. I noticed this first on my Sony XBR910 TV with DVI input though so it definitely isn't a result of the active VGA converter.

Sorry for the bad quality, but my GN2 is old now lol

The visual is very smooth, even smoother than with the combo OSSC + C2, hail Eizo !!!!

Next step, trying to hook the 29" 31Khz NNC's Toshiba !!!

[marqs]

side question: how are the OSSC scanline patterns generated? is it based on the input resolution of the game? or the output resolution of the OSSC? is it a set stock pattern every time?

Line1x, line2x: every other output line has scanline masking. Line3x: every third output line has scanline masking. Depending on alignment option, either first (top) or last (bottom) of the group of replicated lines is the one which gets masked.

Remember that there's almost no LPF for VGA input, so all inperfections in the signal show up easily. Try setting "480p in sampler" to "DTV 480p" for DC via VGA if you haven't done it already. Adjustment of sampling phase may also be needed for some VGA modules.

I've only been using DTV 480P as 640x480 mode results in a more squished image that doesn't look as good. I'll see if adjusting the sampling phase helps. Just trying to figure out what has changed as the image was perfect for the first couple months with the unit on default settings apart from setting RGBHV to use DTV 480P.

I wanted to see how the PSP War of the Lions remake compares in sharpness on a PSTV and on a PSPgo through component zoomed in with the DVDO Edge, with or without the OSSC's line X2 mode.

It's strange, some PSP games have a weird blur filter applied to them (war of the Lions for instance) (my theory is that developers used it to hide dithering). I assume you're playing on an original DVDO edge in game mode (is that correct?)

The original Edge doesn't have access to detail enhancement or edge enhancement in game mode (from what I've been told), but the DVDO Edge Green does (I did some testing earlier in the thread). Experimenting with color and contrast settings can also yield pretty good results. I've also heard that the XRGB-mini frameMeister has a pretty good sharpening/scaling engine when it comes to PSP games. When I have time I'll do some more PSP+OSSC experiments.

With the anti-slowdown patch applied this version of FFT is still a pretty awesome port. (The only thing I miss from the psx version is the reverb on sound effects).

The visual is very smooth, even smoother than with the combo OSSC + C2, hail Eizo !!!!

Very nice monitor! (What year is it from?)

Line1x, line2x: every other output line has scanline masking. Line3x: every third output line has scanline masking. Depending on alignment option, either first (top) or last (bottom) of the group of replicated lines is the one which gets masked.

ah, thank you for clearing that up marqs.

side note: in 480p2x mode I'm having a lot of trouble getting the scanlines to line up properly. is anybody else having scanline issues in that output mode?

[Thomago]

It's strange, some PSP games have a weird blur filter applied to them (war of the Lions for instance)

Afaik, the blur comes from the fact that War of the Lions is rendered in PS1 resolution internally and then shoddily upscaled to PSP resolution.

[Blair]

interesting! although I'm not sure about that. the PSP emulator has an option for removing "filtering" and War of the Lions looks incredibly sharp on it. (its scan-lines options at 1080p are a bit thin for my tastes).

[ZellSF]

If you have a modded PSP there's a homebrew unstretch patch that removes the scaling blur, but you lose widescreen in the process.

Thanks, I think it's from early 2000's
I've just got it since 2 month, I like to think the ossc will render his best with a pure 480p screen :p

[Blair]

I'm betting that as long as it's being fed a decent signal the OSSC will look phenomenal on almost every screen. if you ever get a chance I'd love to see some more high-resolution close-ups with gameplay on your Eizo. (might want to adjust the cameras white balance setting a little, on my android phone the "sunny" setting seems to work best with CRTs)

@BuckoA51, you took some pictures of the DVDO Edge using 480p2x mode. can I ask how you got that working? can't seem to get it working stable on my green.

[Blair]

Tried now around 7 TV's, but no luck with x3 mode
Think I have to buy finaly a bigger pc monitor.

did you try setting the tx-mode of the OSSC from DVI to HDMI? i've had good luck doing that with some tvs that would not accept x3 mode.

also, make sure you know how the hdmi inputs on the set work, sometimes one HDMI port will be listed as its a hybrid port. or as the best one for PC/DVI input. alot of samsungs do this with hdmi port-1 .

some times to activate PC mode you have to go to the TV's inputs list and use the rename function and set input-1 as "PC". that will usually give you more flexibility with resolutions and timings.

but do give the TX settings on the OSSC a try first.
