• shutterTiming: A subparameter of motionBlur used to specify 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 shutterTiming
parameter.
• shutterOffset: A subparameter of motionBlur representing the offset from the current
frame at which the blur is calculated. Default is 0; previous frames are less than 0.
useReference
Applies the transform to the image or doesn’t. If it doesn’t, and you have animated values,
useReference applies a motion blur to the image, but does not actually move it. This is
good for adding blur to plates. 0 = Move image. 1 = Smear-mode (image is not moved).
• referenceFrame : A subparameter of useReference used for image stabilization. By
default, this parameter is set to “time,” that is, in reference to itself. However, if
inverseTransform is set to 1, you are stabilizing, with the assumption that any
animation you have applied matches up to the source animation. Setting the
reference frame locks the movement in to a specific frame.
Orient
The Orient node rotates the image by 90-degree increments, resizing the image frame if
necessary. (For example, for one turn on a 300 x 600 frame, it rotates it 90 degrees, and
makes a 600 x 300 frame.) You can also apply a Flip node and Flop node to the image.
To rotate in degrees, use a Rotate node or a Move2D node.
Parameters
This node displays the following controls in the Parameters tab:
nTurn
Number of 90-degree increments the image is rotated, for example:
• 0 = no rotation
• 1 = 90 degrees turn counterclockwise
• 2 = 180 degrees turn counterclockwise
• 3 = 270 degrees turn counterclockwise
• 4 = no rotation
flop
Flops the image left and right around the Y axis.
• 0 = no flop
• 1 = flop
flip
Flips the image up and down around the X axis.
• 0 = no flip
• 1 = flip
