- [Instructor] Now we can take a look at the screen…replace functions in Keylight right here.…The purpose of this is whenever the matte…is processed, it can introduce edge discolorations.…And this is designed to address that.…Let's take a look at how it works.…Let's go to the view and punch up the status display.…You notice that we see the typical status,…pure white, pure black, and some gray pixels.…However, when I turn on the inside mask,…I get these blue pixels here.…
This is Keylight telling me that these pixels…were affected by the inside mask.…Next, we'll turn on the outside mask…and those are turned red.…That identifies them as being affected by the outside mask.…Last, I'll adjust the screen dilate…and look what happens here.…I get these green pixels.…This is Keylight telling you…that these edges have been affected…by a screen dilate operation…and now there's discoloration.…This is what we're going to fix…with the screen replace function right here.…
We'll switch the view to composite,…and we can see the hideous edge.…
