good to know. thanks

It took me only a few minutes to set the optimal timings for 288p 🙂 I expect its going to be not much harder for other resolutions except interlaced.

Thanks for the update. Looks great. Better than gsb control with motion adaptive deinterlacing.
I made a short video to compare OSSC vs OSSC Pro image quality:

Day and night 🙂

thanks for clarification. Just one last question. The vertical resolution is not the original one when using PS2 optimal timings. 448-> 480 so the screen ratio is slidly off. Why it is not recommended to use v.active 224/448 as optimal timings? IMO it does look sharper and the screen ratio is closer to the original.

[Retrorunner]

Thanks for your response.

1. It makes from logical perspektive sence but if you take a look on the wii optimal timings for 4:3 and 16:9:

H.active: 640 in 4:3 mode, 720 in 16:9 mode, H.samplerate: 858 for both 4:3 & 16:9 modes

its kinda contradictory. The samplerate is the same for both 16:9 and 4:3.

You are using swiss to force 480p? Have you tried a GC game which supports 480p natively (as an option)? My guess it might be a problem with swiss.

[Retrorunner]

Which mode do you use? 5x? 4x?
Reset your ossc settings and set output to passthru and than check if the dropouts happens again. (for testing purpose)

After several days of searching for the suitable capture card I found the golden one. 🙂
First I planed to buy the 4k cam link but unfortunatey the cam is not able to capture 240p passthru and other resoltuions like psp mode. So I kept looking and found this channel: https://www.youtube.com/watch?v=nZJkpQBigTg&feature=emb_title the owner is using the elgato hd60 s+ (Important: not the standard edition without +) in combination with OBS. I was able to test the card today and so far every resolution I use in my setup/setting worked perfectly (except 480i 3x Laced as expected).

240p Passthru, 2x, 3x, 4x, 5x Line (including optimal timings for all modes)
480i Passthru, 2x Line, 4x Line
480p 2x Line
1080i,2x Line

Even changing v and h.active I was able to record footage. Also working with mclassic except the sound is off.
As long you set the correct resolution in OBS you will get the correct ratio.
The only downside is the card is losing connection when the game or me changing resolution. I guess a scaler should be helful in this scenario.

Here is some footage which I recorded (the youtube compression is horrible)

OSSC Passthru – OSSC 4x Line (bob) and 1080p forced via GSM:

Crash Bandicoot 5x Line optimal timings:

if you have any questions feel free to ask.

Sorry for the double post. Which hdmi splitter (from EU sellers) should I use for the elgato 4k cam and it is possible to capture 240p (with elgato cam 4k without line doubling)?

[Retrorunner]

I would like to record (not streaming) some gaming footage using the followig setups with PS1, PS2, GC, Wii (u), Dreamcast, N64, PSP.

1-4x Line with 240p
480i
480p 2x Line
720p
1080i
1080p

I guess 480i/576i ossc passthru will not work? or maybe there is a workaround?

[Retrorunner]

I solved the problem. my scart rgb switch does have audio out.

I am not able to install the new test image from borti:

ossc_0.80beta-bl_test.bin
https://github.com/borti4938/ossc/tree/dev_lcdbl/fw_build

because of the “invalid image” message. I tried several times to trigger the update. Tried different micro-sdcards same result. When using older images (also on bortis page ossc_0.79-bl_test.bin) it works on the first attempt. Any idea why its not working with the image: ossc_0.80beta-bl_test.bin ?

edit: wiped the micro sd card, formated with 32fat, used win32disk imager and same result.
edit: ok something wrong with the image after/when downloading

Tested: Scanlines 37%, Multiplication vs Subtraction und hybrid contrast: Low. The color is definitly closer to the original with multiplication (bortis scanline solution) as with substraction. Combined with hybrid low contrast its even looking better 😀 Great work from both of you guys.

[Retrorunner]

Borti’s method has brighter scanlines with more accurate color mostly at the lower scanline strength.

Yep, thats why I would like to see a combination beetwen hybrid and bortis scanlines if possible 🙂

However the color loss I am seeing in your pictures should not be so big. The picture of the car is almost black and white.

You mean these two screenshots?

Thats the huge difference I have when using bortis and standard scanlines at 37% and even I use standard scanlines at 18% I have still more color loss compared to 37% bortis scanlines.Changing scanlines position has no effect on color neither brightness.

I am the only one who tested bortis scanlines and see that big difference in color?
