Removing color casts with spill suppression

“

- Now that we have a pretty good key, it's time to adjust the spill. Spill refers to the key out color showing up in the edges of the subject. In our case, having some of the green showing up on the young man. Let's go ahead and open the sequence named "2.4 Removing color casts with spill suppression". Let me go ahead and change the Alpha Channel view to a Composite view. I find it also very helpful to zoom in so that we can better see the color spill. So, I'm going to change this program monitor panel view to 100%. I will also turn the background tracks visibility off, and when he moves his hand, we can see some of the green right here on the edges. Let's adjust some of the parameters so that we can get rid of the color spill. Let's start with Desaturate. Desaturate desaturates colors that are close to being fully transparent, like the ones on the edge of the subject. I can change this value to a lot or very little. This is going to work well at lower values, so I will leave it at the default, which is 25. The next one is Range. This control how much of the spill will be corrected, more or less. I will change this value to about 63. The next value is for the Spill. This is how much we're compensating for. It uses a color that would be on the opposite two hours on the vector scope. So in our green, the opposite will be magenta. It uses this color to neutralize that shade of green. Right now, it is a little too much, so I will change the value to less. I think somewhere at around 43 will work. Luma, this restores the original luminance of this object. For this, we can leave it at its default value, which is 50. I understand that the young man looks a little bit too magenta, but that's okay. Coming up next, we'll color correct this footage to match the background.
