Hi guys!
Herę came the day when I have the issue that happens sometimes and until this day I have never dig for the solution. Until now because this is so annoying. Why 3D Keyer gives me such result?
Example 1

Example 2

instead of the right effect?

I am wondering what causes this as the set, camera and environment are exactly the same every time we record session and usually there are no problems.

Your key color in second and third image is not green color, so it keys some random areas. Sample the actual green screen backing.

Surę, I know, but it is a green color in reality, its just color settings in DaVinci makes much less vibrant. Anyway, it's the same with other recordings and mostly it doesn't have a problem like this. It happens only from time to time and appear to be random somehow. Therefore I have a question about it.

I’m not talking about your footage. The rgb values in your keyer settings are not representing green color. You have somehow set your key color to be a reddish tint (red channel value is bigger than green and blue) and thus it keys some random areas like face and hands.

Good catch, Hendrik! And in the third image, the key color is almost neutral (grey).
