Hi, is it possible to input key and fill signals and get a normal source with alpha?
I want to do the keying in an Ultimatte and the compositing in vMix. I have a BM Decklink 8K capture card.

Thanks!

Never mind, I found it. Key/fill input under the Colour Key tab.
My mask was inverted, but it can be flipped in the Ultimatte. Still it would be nice with an invert key in vmix as well.

It's not as simple as checking a box, but if you swap your "Black Stretch" and "White Stretch" in your Key/Fill input's "Color Adjust", then run it through a Mix input, and set the Mix input as your Key/Fill input, it'll invert.
