Hello everybody,

Luma key with Mix input seems to be impossible.
I chose the input 26 as key-input in Mix2 and then the Mix2 in layer 4 of Nokia

What happens here?

Thank you

Thanks for your answer, but this covers not my case

Doing the same with another input works like expected but with the Mix2 it does not work

The intention is to do a fade or something like that in the circle

I realized that the problem is the key source. With a bitmap, it works. But my circle is a mp4-clip and that makes problems.
I will try a sequence of pictures next.


With a sequence of pictures the key looks good but there is a tiny bright border

This is a mix input with output set on Decklink and key-source komp 1_0000.png

And this is the Decklink input and the same key-source

What can I do?
