Hello,
I've tested internal keying for lower third purposes with a Blackmagic DeckLink SDK 10.1.4 and tried sample GdiKeyer.exe (in the zip Blackmagic DeckLink SDK 10.1.4\Win\Samples\bin) on DeckLink 4K Extreme 6g using HDMI as input and output (in 1080i60 video mode).
The problem is that the output video turn in green/purple colors. I can't say if overlay color elements are corrects (seems yes)
What may be the problem ? config, drivers (using BMD 10.4.2 on Win7 64bit), SDK, hardware, else ?
here is the program output:
and resulting image
Same issue occurs using CasparCG with internal keying and placing lower thirds in overlay.
Thank You for support
Lorenzo
