Product overview
The Background and Input Clip thumbnails have right-click menus with which you can
switch from a given source to a white, black, or checkerboard image and back again. For the
Background thumbnail, these images can help you analyze the quality of the key for the input
clip. For the Input Clip thumbnail itself, you may want to switch to one of these alternate
sources to see the size, position, and orientation of the input clip’s plane. However, assigning
a new source in this fashion can cause you to lose a custom mask that you’ve painted.
For more information, see the following sections:
“Layers, inputs, and virtual sets” on page 22
“Assigning content to layers” on page 63
