Pivot Location
The Point of Rotation is the point in 3D space where the channel is rotated around. Before you
can rotate the channel, you must first set your Point of Rotation, or Pivot Point.
There are two methods of selecting a Point of Rotation:
• Pivot Presets — This allows you to select from a list of pre-defined locations. The Pivot
Presets apply to channels only, and is not applicable to objects.
• Pivot Position — This allows you to select the location manually in 3D space.
Both methods are described in the following procedure.
The Point of Rotation boxes on the menu indicate the current point in 3D space that the channel
is going to rotate around. This point is represented by a small circle inside each box.
Operating Tip — If you have cropped the channel, the dotted line in the Point of Rotation
area represents the original size of the channel, and the solid line represents the cropped
channel.
Use the following procedure to select a Point of Rotation for a channel:
1. Press the SEL button on the Keyers Module for the Keyer that you want to adjust the
point of rotation of the channel for. The S&T MD Position/Crop Menu 1-2 is
