Vectorscope and skin tones

Hello, does anyone have experience with the Vectorscope?

How reliable is the Vectroscope display in Kdenlive? When I bring the skin tones to line I, the face becomes quite yellowish.

Did you calibrate your monitor?

Hallo Bernd,
my monitor is the BenQ PD2705Q and it is supposedly calibrated from the factory. I hope that’s enough.
However, I have also discovered that when I use images from TV or other correctly adjusted images, the color deflection is always exactly on the I-line. So it seems to work.

Here is the screenshot:

It looks like Kdenlive is working perfectly. How nice!
