  Complex gradient + key

  Posted by Rick Turners on February 19, 2011 at 3:44 am

  I’m trying to create a gradient orange > blue in the sky of a shot.

  However, a man walks through the shot.. so I can’t simply do an inside/outside type of thing.

  I really need to make a key/qualifier of the current sky, and then within that key, create an inside/outside. (so I don’t effect the ground and the mans face with the gradient)

  Is this possible?

  That’s great. It’s certainly not in Color.

  Could anyone elaborate on the process of achieving this?

  hi…

  i think its just a matter of combining mattes -> see alex van hurkman tutorial: https://vanhurkman.com/wordpress/?p=560

  Yeah you should be able to create a subtractive matte and track the person walking though the shot. which will subtract from the gradient one.

  You do sky gradients in Resolve basically the same way you do them in Color. Two serial nodes with the sky keyed. One blue and one orange with linear or polygonal Power Windows softened and overlapping to create the gradient. If you have the sky keyed then it shouldn’t matter if someone walks into frame. If you want to get fancy, render out a gradient matte and use that.

  Nattress has a gradient FX node for Color too.
