x,yPan |
float

0,0 | The x and y pan 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. |
