OSSC (DIY video digitizer & scandoubler)

[fafangus]

Hello
Here is a video of the OSSC combined with the CII 3300 (system megadrive 1 jap in Av3 RGBHV of the OSSC) :

Great job together
Fudoh (as a specialist of the two units) do you thinks it's a reliable solution ?

PS : the audio out of sync at the end of the video is probably due to the framerate that YouTube can't handle (on my computer everything is fine)

Tell me what you think about

Ciao

[Fudoh]

do you thinks it's a reliable solution

due to the missing framelock on the CII you'll have little framerate hiccups once in a while, since the CII's output refresh rate will never EXACTLY match the input. If you don't mind these, it's certainly a killer-combo.

Has anyone tried the linetriple/720p with a micomsoft xcapture-1?

Working with my sfc, but not tested others systems

Does the 256x240 optim. mode work for you through scart? I was able to get a sort of stable image in this mode using a Sync Strike (RGBHV) but the colors are messed up. Through scart the picture just drops out and the fps can't reach higher than ~10. When using the AV3 input in RGBs mode, the colors are correct but the signal drops out just like when I'm using the scart cable. The driver picks the signal up as 1280x768 but I have seen it occasionally pick it up as 1280x720. I have no issues with the generic modes (using an SC-512). I'm using a sync-on-luma cable at the moment.

@BuckoA51 - I'm having some trouble creating an account for the VideoGamePerfection forums. The activation email doesn't pop up in my inbox or my spam folder. What could be causing this?

Well, I don't see it if there is, I mean, once I paused SF 2 turbo on the SFC and after that I restarted the game, I've see a little drop of 0.3 or 0.4 sec, but don't know if that's the CII or the SFC itself...I have to play long time ^o^

Do you think the hdmi passtrough of the CII let me use the no lag with my tv set
I mean my tv accept X3 line triple on certains hardware (have to test a bit more for others), so I get no lag like that, I suppose the CII add (had) a little lag, but if I use the passtru fonction, it's like I hook directly the OSSC to my tv ? Does this function works when the CII is off ?

Clearly the CII improves pictures and position/overscan, and it's able to handle X3 pal, the killer combo it's that for me, waiting the new output modes

Through scart the picture just drops out and the fps can't reach higher than ~10. When using the AV3 input in RGBs mode, the colors are correct but the signal drops out just like when I'm using the scart cable. The driver picks the signal up as 1280x768 but I have seen it occasionally pick it up as 1280x720. I have no issues with the generic modes (using an SC-512).

The only test I've done hooking directly the OSSS to the Xcaputure-1 was with the AV1 rgbs input with my sfc 1 chip with csync cable
Don't tested this output mode, but now I use my Xcapture-1 directly behind the CII, so it's not like directly behind the OSSC...
But I have also some coulours artefact with RGBHV with AV3 in (Megadrive 1), but it's a more stable signal, for the Amiga it's the only way (for me) to get a stable picture

[Fudoh]

you won't notice something like this with a game like SF2, but if you throw in something that's smoothly scrolling - either vertically or horizontally you might notice a hiccup every second or so.

passthrough would just "pass through" the signal, so you wouldn't gain any added compatibility.

[Fudoh]

Did somebody test the OSSC on an iScan HD+ yet?

[fafangus]

Some shmups over MD1 :

That is this kind of games you're talking about ?
Maybe I'll test with Artemio's 240p test suite

Barely any hiccups, if that video is accurate then it's smoother than with my modded PAL MD2 + DVDO + Sony W6.

[Fudoh]

yeah, you got small hiccups every few seconds and a big one every 15 seconds or so. That's because the CII tries to keep track as long as he can, but has to adjust the timing at some point.

[fafangus]

Yeah I don't have played with CII frequency in output, just playing it rough, I have to make the CII match the OSSC, but I see that the OSSC is changing Hz very often, so I think it's useless
In VirtualDub it show 60.096 fps, I recoded to 60.10 fps (to mach as much as I can for the audio sync, don't know why I've got this problem, even with others hardware), but I think YouTube recoded it at 60 fps.
So yeah it's like that when I play, I don't see anything wrong at all, but my eyes as not as hone as yours...
I'm still happy

> Fudoh could you tell me the additional lag the CII gives to that circuit ?

just got my OSSC today, looks great! now I'm just trying to figure out which DVI + stereo to HDMI convertor I should buy.
Something like this works? http://www.ebay.com/itm/DVI-R-L-Stereo- ... SwMNxXZENZ
here's one a bit cheaper: http://www.ebay.com/itm/New-DVI-to-HDMI ... Swc1FXad-9

Ok, reviewing the video after the work, I see that youtube added a "deformation", a scaling artefact that I don't have on my original video/playing...
I'll try to up this to gamersyde/MEGA to see if it's better

The top one looks like a rebranded version of the Lindy one I reviewed that basically sucked (audio was way over-loud and distorted). I'd try the cheaper one.

480p line double works on the DVDO Edge, but I wasn't that impressed with the quality of it, more details here:-

@BuckoA51, any recommendations for a DVI to HDMI adapter with no audio? I have a Home Theatre PC and I'll use the audio out from the OSSC directly to the Line In on its soundcard.

HDMI can carry DVI. So all you need is an entirely passive adapter for a purely digital signal. No chance of signal loss or deterioration, as long as whatever you get works, you don't need anything special. Something like this will do:

[cfx]

Molex (available at Mouser or Digikey) and probably others also make cables with HDMI connector on one end and DVI on the other if you prefer not to use an extra adapter.

[Guspaz]

As do Monoprice, which probably cheaper for the item/shipping than Digikey

[Xyga]

Going to try the OSSC on an HP 27xw monitor within the next two weeks (same as Everblue's).
Hope it'll handle more multiple modes than my Sony W6 (it probably will).

I swear to God this little thing is a great performer. No evidence of black or white crush and momentary sync dropouts are very, very rare. I've even used it with my PS3 in the past (seems to get around HDCP). Plus if you smash it to pieces by mistake you can always buy another one. An HDFury is overkill in my opinion.

I picked one of these up, and while it's great for the price, it is in NO WAY a replacement for an HDFury

The picture is noticeably softer and more washed out than my Fury2, which also transcodes to component and outputs optical audio.

[LDigital]

I got mine. It's fantastic for all my systems except it will Not recognise my neo geo mvs 1fz at all. It just show no-sync.
I tried so other sync settings marqs provided but still no dice

What input do you use, try AV3 rgbhv with a sync strike or a sync cleaner like this...

I've got problem with 480i signal (only tested saturn for the moment), the picture is cut in 2, some tips for that ?

[ZellSF]

I was sure I posted this already:

1: Repeating my request for 240p passthrough, it's not an essential feature but if easy to do would be useful for connecting the OSSC to a scaler that can do better with a unmodified picture that either lacks RGB input or has a terrible A/D stage. Example being connecting to a XRGB-mini. I know there's basically no scaler that fits that criteria, so again not an important feature at all, but if it's easy to implement...?

2: I asked for discrete IR buttons for line3x off and on, while I still think that should be implemented, if you want to conserve IR buttons then having discrete buttons for profiles would be more important. Example being a line2x/scanline profile and a separate line3x profile to easily switch between.

I'm using my XPC-4 to transcode at the moment, but the image from the El Cheapo VGA adapter I've used is not notably worse (and personally I don't need the other features you've referred to). Bear in mind that that particular model (if we do in fact have the same one) is an extremely cheap, generic converter. There are many, many others out there. I think the HDFurys are extortionately priced and there's something of a placebo effect involved, but each to their own.

Ok tested my ntscj ps2 in yuv with pal DQ8 > 576i works, not as sharp and beautifull as the FM but a descent stable pictures (no flickering, or flashes like the xrgb-3)
Hooked it in av1 with scart (selected yuv av1 signals on OSSC)

Anyone have tried 480i saturn titles, or N64 RE2 ?

[ZellSF]

I got one of these things:
http://www.ebay.com/itm/262474410772?_t ... EBIDX%3AIT
Don't get one of those things. It will not help with OSSC compatibility, in fact it does not seem to recognize nonstandard signals at all. 480p,720p and 1080i work (but with some issues) so I guess I will have some use for it in combination with lag tester to figure out the lag on my component video equipment.

Really curious about if a better quality HDMI to component converter like maybe a HD Fury would have better results, but those are too expensive to buy just for testing

[Calle W]

Been playing around with the OSSC for about a week now and it's a wonderful piece of hardware. I've only had two issues so far, but they don't really have anything to do with the unit itself. The problem lies with my capture card. I'm using the Micomsoft SC-512N1.

https://youtu.be/hs1oa1aVKOY

https://youtu.be/vG2Lf3wSVSE

The first video basically shows that the capture card won't accept the 480i passthrough mode. Is there anyone on here who could try this out with the same (or similar, XCapture, USB3HDCAP SC-500N1 etc.) capture card. It would be extremely appreciated. The same issue is present on my old BenQ G2400WD but I'm never gonna use it for gaming anyway.

The second video shows how the capture card handles the linetriple modes. First it shows the generic 4:3 mode, then the 320x240 optim mode, then the 256x240 optim mode and finally reverting to 480p. First of all, the card will drop the signal when using the SNES/SFC unless I set the HDMI/DVI bandwidth to 175% in the driver. This is only possible to do in the latest driver, so I can't use any of the older drivers. The generic modes work perfectly, and I assume the 320x240 mode also works with appropriate sources. I don't know why the 256x240 mode is giving me inaccurate colors though. Also, the only way I could get a stable signal in this mode (when using a scart cable) was to change the TX Mode to HDMI. I also switched to an HDMI cable, just because. Sometimes when I change settings on the OSSC or in the driver, the HDCP logo pops up for about .4 seconds or so.

I've tried both sync-on-composite and luma cables, with and without a distribution amplifier, but the results have been the same.

@blizzz - In your review of the OSSC you showcased the difference between 480p and 720p. Did you use the 256x240 mode in these comparisons? If so, the SC-500N1 seems to be more compatible than the SC-512N1.

I know marqs used the SC-512N1 when he gave us a sneak peak at what the OSSC could do, so maybe he could shed some light on this. Any kind of help would be appreciated.

EDIT: Just took a quick look at the compability spreadsheet and saw this: "SC-512N1 receiver bandwidth set to 125% to avoid dropouts caused by uneven hsync from PPU" from marqs own test of the SNES. I wonder why my setup is giving me weird colors in the same mode.

[blizzz]

No, I couldn't get the 256x240 mode to work at all. The Metal Slug X screenshots are using the 320x240 mode though.
