Ops 12–2 • Squeeze & Tease Basic Operation Vision Operator’s Manual (v12.0 MD)
Operational Overview
The Squeeze & Tease option operates by manipulating keys in 3 dimensional space. This allows
you to position keys in front of, or behind, other keys, and make keys appear larger or smaller
than they are. You can also apply environmental effects to the keys such as lighting, or apply
video manipulation effects such as colorization. To apply any of the Squeeze & Tease effects to a
key, you must have the FLY KEY button in the Keyers Module or Downstream Keyers Module
on. When Squeeze & Tease resources are applied to a Keyer, the selected key type (Self Key,
Auto Select, Chroma Key, or PST PATT) is said to be Flying. You can fly any type of key,
provided you have the available channel resources.
When you fly a key, the video signal for the key is contained in an image. By positioning or
rotating, or applying other linear, environmental, or color effects to the image, you are defining
how you want the switcher to display the video signal for that flying key.
The image can be positioned anywhere in the virtual 3D world; however, it is only visible on
screen if it is within the Visible Area (Figure 12.1). This allows you to perform transition effects
where the image appears to fly in from one side. The image is being taken from a position outside
of the Visible Area into the Visible Area.
