Web Presenter SDI input saturation problem

Hello - I have a Blackmagic Web Presenter with the smart panel. Using OBS software and 2 Sony FS7 cameras. Both cameras are set to 1080 60i. The camera coming in HDMI looks great. The camera coming in SDI has really boosted chroma levels making skin tone look like Oompa Loompas. I have already gotten another unit from Blackmagic but still having the same issue.

Thanks!

A few questions:

1. Are you using SDI port 1 or SDI port 2 on the FS7? Is there any difference in output between the two?
2. If you press the STATUS CHECK on the FS7 and go to the Video Output Status screen, what does it show for the output settings for the SDI and HDMI ports?
3. If you connect SDI output from the FS7 to a monitor do you see the same problem?

Dave - Thanks for your reply!
1. Using SDI 1
2. Already left the studio for the day but will check this tomorrow and post here. Both outputs are set to 1080i 60.
3. SDI output looks fine on 17" monitor. I only see the problem in OBS. Same problem in Skype.

Checked the Status Screen and both SDI and HDMI outputs show 1080i.

Hmm Weird.. No LUT applied to an output?

Nope, no LUTs applied.

If you connect the SDI program output from the Web Presenter to a monitor, do you see the same color shift?

When viewing the SDI output from the Web Presenter on my Sony 17" monitor, there is no color shift.

Well, I'm about out of ideas on this one. Given that the program SDI out from the Web Presenter is ok, it seems like there's some kind of problem with color handling when compressing the signal to send over USB to the computer.

Now why this would be different between SDI or HDMI, I'm not really sure. Ordinarily I'd suggest that it could be some difference between color depth (8-bit vs. 10-bit) or chroma subsampling (4:4:4 vs. 4:2:2, etc.) on the output. But I think the FS7 is supposed output 10-bit 4:2:2 over both HDMI and SDI.

If the HDMI input into the Web Presenter is ok, I suppose you could run SDI output from the camera into an SDI to HDMI Micro Converter, then HDMI into the Web Presenter. Not ideal, but might be one workaround.

Well I'm considering this a "feature". I know this isn't necessarily how the box is intended to be used but perhaps it's something Blackmagic can address in a future software update.

My workaround is to use my UltraStudio SDI. When the Sony FS7 is fed via SDI to the UltraStudio, I can add it as a device on OSB and it comes in looking fine. If I send the SDI output from the UltraStudio to the Web Presenter (UltraStudio has to also be added as source in the scene on OSB so it is active) it also looks fine and allows me to use the 2 switcher buttons on the Web Presenter. Thanks to those chiming in and trying to help!

Hi
I don't know much about Sony, but on my JVC you can change the SDI output to Composite or Component in the settings.... that might be something to look at....if possible on your nice Sony ?
