Hope you are all well this holiday season!
Davinci Resolve 17 came out with a new feature where you can key out a green screen in the Edit Page.
This tutorial will show you how to use the 3D Keyer effect.
If you get a light green screen after keying out the color try clicking on DESPILL in the Effects section under the inspector tab.
