Using one of the video clips from the
website of the woman on the Greenscreen, began to look into keying. To make the
key easier, and not having to key any unnecessary information I created a mask
around the woman, this is known as a garbage matte. I then applied the key light plug in to this
layer and selected the green as the color to be removed. While this looked
good, It wasn’t completely right, so in order to tell what details the of the
key was being removed I the effect view to screen matte.
This revealed that some of her face and
jacket had been turned transparent from the key. In order to fix this, I
adjusted some of the screen matte options. Specifically ‘Clip black’ &
‘clip white’ This gave a much nicer key.
To stop the edjes being to harsh and to get
rid of any minor imperfections I adjusted the screen softness. To show how the
key looked, I placed another clip behind the keyed layer.
