Automate 4-color gradient?
Hi,
Is there a way to pick the color of the 4-color gradient automatically over time?
Do you know any script or expressions would do it?
I have a “4-color gradient” to fill masked out parts. On the layer with 4-color gradient I pick the colors of the Footage next to the mask. That works fine with plain color or blurred areas. But as soon as the light in the shot changes , the colors get darker or brighter. So it would be nice to have a way to change the colors of the 4 corner points automatically in every frame.
Or maybe there is a much better way?
Thanks for your help!

On the footage layer make 4 Color Control effects (in Effects > Expression Controls > Color Control)
Then for each Color Control, add the sampleImage expression:
sampleImage(point, radius = [.5, .5], postEffect = true, t = time)
— swapping in the correct value for pointAnd finally, in the 4-Color Gradient effect add expressions to each color linking them to the Color Control effects
Hope that helps!
