Hello there,

so I am currently looking to get a website with transparency into xpression. For that I setup an OBS scene with an NDI filter that only outputs that one browser source.

When I'm trying to add a NDI framebuffer in Xpression I can set the output name and input name, but the live source shader will show no NDI inputs. Since both NDI in- and outputs are on the same machine this should not be a network problem. It also only gives me an output and no input but no option to add an input. I should add that I'm on Xpression 10.5 so NDI should be supported

------------------------------
Best wishes,
Johannes

I assume you are running XPression Studio Edition. That edition is limited to 3x Inputs. You have 2x BlackMagic and 1x Directshow inputs already, so the software is restricting you from adding the 4th input. 

If you want 4 inputs you need to purchase the Extra Input option for XPression Studio.

If you want more than 4 inputs you need to upgrade from XPression Studio to XPression Studio Flex.

Hi 

Trying to do the same with XPression Studio Go. 
I'm trying to configure a NDI input and a Fill&Key AJA output. The problem is that when I add the NDI in the hardware, it's coming with Inoit and Output without the possibility to delete the Ouput. 
Do you have a solution for that ? Or another solution to add a webpage with transparency as material ?

Many thanks !

• delete all the IO in the XPression hardware setup
• add only the aja outout
• add the ndi framebuffer
• the NDI output should show as "preview only" 
• the AJA output and NDI input should work normally

Thank you for your answer. 
After making some tests, it seems that it's working with Studio Go! but not with Studio SCE. 
With SCE, I can't create the NDI after having added the AJA. Do you know why? It seems complicated to understand exactly the differences between all versions.

The same steps should work with Studio SCE. 
Studio SCE is limited to 1x output and 1x input. With outputs beyond the first one being labeled as (preview only) and inputs beyond the first one not being shown. 

Did you delete all the input and outputs in SCE before adding them in the order of: 

• add only the aja outout
• add the ndi framebuffer
• the NDI output should show as "preview only" 
• the AJA output and NDI input should work normally 

Can you send a screen capture of your hardware setup?

I've done the test on the same computer with the two different licences and with Studio Go! it's working.

Build are 12.5 (6128)

Oh....the NDI menu does not even open!?

That looks like a software bug. I will try and reproduce. Thank you for the video.
