QuickShape Node Parameters
The following table lists the QuickShape parameters.
Parameters
This node displays the following controls in the Parameters tab:
width, height
The overall width and height of the frame in which the rotoshape is drawn. Defines the
DOD. These parameters default to the expressions GetDefaultWidth() and
GetDefaultHeight().
bytes
Bit depth, 1, 2, or 4 bytes/channel.
xPan, yPan
A global pan applied to the entire shape.
angle
The center of transformation for the angle and x/yScale parameters.
aspectRatio
This parameter inherits the current value of the defaultAspect global parameter. If
you’re working on a nonsquare pixel or anamorphic image, it is important that this
value is set correctly to avoid unwanted distortion in the image.
xScale, yScale
A global scale applied to the entire shape.
xCenter, yCenter
The center of transformation for the angle and x/yScale parameters.
motionBlur
Motion Blur quality level. 0 is no blur, whereas 1 represents standard filtering. For more
speed, use less than 1. This value is multiplied by the Global Parameter motionBlur.
shutterTiming
A subparameter of motionBlur. Shutter length. 0 is no blur, whereas 1 represents a
whole frame of blur. Note that standard camera blur is 180 degrees, or a value of .5. This
value is multiplied by the Global Parameter shutterTiming.
shutterOffset
A subparameter of motionBlur. This is the offset from the current frame at which the
blur is calculated. Default is 0; previous frames are less than 0.
