Defaults
|
Function
|
angle |
float
|
0 |
The rotation angle. Positive values are
counter-clockwise rotation. |
aspectRatio |
float
|
1 |
The aspectRatio, for when you are using
anamorphic frames. |
x,yCenter |
float
|
width/2, height/2 |
The x and y rotate center values. |
motionBlur |
float
|
0 |
Motion Blur quality level.
0 means no blur, whereas 1 represents standard filtering. For more
speed, use less than 1. This value gets multiplied by the Global Parameter
motionBlur. |
shutterTiming |
float
|
.5 |
Shutter length. 0 means no
blur, whereas 1 represent a whole frame of blur. Note that standard
camera blur is 180 degrees, or a value of .5. This value gets multiplied
by the Global Parameter shutterTiming. |
shutterOffset |
float
|
0 |
This is the offset from the
current frame at which the blur is calculated. Default is 0, previous
frames are less than 0. |
