How to Fix: I can't change my settings for my capture card and from everything that I'v

Blackmagic Design 4K30 capture card won't allow changing settings from 16-bit to 24-bit, causing compatibility issues with certain sources.


The issue you're experiencing with your Blackmagic Design 4K30 capture card not allowing you to change the settings from 16-bit to 24-bit 48kHz is likely due to a misunderstanding of the card's specifications and limitations.
