Hi everyone, I recently tested my machine with a Decklink 8k Pro. It works in 2160p50 incl. key output. The config of channel 1 is identical to my Duo2. Key output is on connector 2 on the 8k Pro. BUT there are no additional output channels possible as the 8k Pro is only one Decklink device to the system. If the card is set to In & Out Mode via BM Software, connector 3 can be use as an input but no more outputs possible.
I also mentioned that e.g. the Transform, Anchor Point and Distort Tools are not working in 2160p (V2.2.0).
