Black level "noise" (Blackmagic Design Video Assist)

PostMon Jan 08, 2024 11:28 am

Hello everyone,

I have a specific use of the device, I use it to record a video output from my computer (from HDMI) to a pixel LED system. It's interpolated by a nova card. Same as led screen system but the picth and sensibility to very low rgb level is higher.
When I bypass the blackmagic I have no light when I send a "black" output. And even if I don't change anything on my setup and just chain the blackmagic on my setup (HDMI in from my computer and HDMI out to the "led screen") I instantly see light on my led (look like 1% level of RGB combined).
I have try to change cables etc. Same whit different video codec/format.

Do you have already experienced this situation?

Thanks
