Hi!
I noticed that when going to 2160p on my 8K pro gen1 i need to set pixel-format to yuv for the outputs to work (Failing to set that somehow blocks the full channel).
When i do that for the key output it shows the fill also instead of key.
What is a correct workflow and settings to get this to work?
quick question, are you setting up two different channel, one for fill and one for key?
I had this impression reading your question
No, one channel 2 decklink devices, 1 fill second key.
Changing the mode to 1080p50 makes it work as expected.
