Today we went over using simple keying to incorporate a green screen subject into another environment/background:
First we dragged the footage into our program, we didn't start a new composition because the comp automatically takes on the properties of the footage when we drag it into our timeline.
Once we've dragged in the desired green screen footage we can key out the green by typing in "key" into effects and presets and then applying the Keylight (1.2) effect
Once this is applied the green can be keyed out with the effects controls:
Using the screen colour tool we can use the eye dropper and select the green (close to the person themselves) and get rid of the green.
Next we inserted the background:
We put this layer underneath the green screen layer, now we have to key it in properly because there is some problems with black line around the subject as well as some areas that aren't transparent. We do this by adjusting the clip white, clip back and screen shrink.grow options under screen matte.
We can also change the view to screen matte to see the green screen footage in B&W to make it easier to edit:
We tried ridding this image of the grey areas - both in black and white parts of the image
We then have to fix the green screen spill that we're getting on our image so we change the despill bias, select a piece-a-skin that doesn't have green screen spill and it will somewhat correct the image
Now we have to fit the person in with the environment for which we apply curves:
Beautiful
