Hello,
I've been trying to figure this out with the UltraGrid guys. When capturing a 12bit RGB444
UHD SDI input signal, the colors are all crazy. When SDI output is 10bit RGB444 UHD, capture is fine. See attached screen shots.
I've tested capture with UltraGrid, FFMPEG and even MediaExpress (Ubuntu). I've tested outputs from both Flame and Resolve (RockyLinux). Always the same results.
2K DCI 12bit RGB444 is fine though, the issue is only UHD.
I've tried several different decklinks, from UltraStudio 4K Mini, Decklink 8K Pro, DeckLink 4K Extreme 12G.
