Desired effect: smooth local (masked) blur (HitFilm 4 Express)
Composite shot. I load my footage on the base layer and apply the desired effect (e.g. auto color correct) until the general image looks the way I want.
Then I copy the layer on top of that layer and apply a blur effect. So far so good. But when I then draw a mask on this layer the color of that spot gets corrected in a very weird way (usually overly bright or heavily over saturated) so that spot really stands out.
What am I doing wrong here? Thank you for your help! :-)
