794 Chapter 26 Transformations, Motion Blur, and AutoAlign
Note: If necessary, you can preprocess images connected to the AutoAlign node with
other color-correction nodes to even out differences in gamma and contrast that aren’t
addressed by the matchIllum parameter.
The Transform Nodes
In addition to the AutoAlign node, Shake features numerous other transform nodes. The
following section includes information on the transform nodes, which are located in
the Transform Tool tab.
For information on the transform nodes that are used for tracking and stabilization
(MatchMove, Stabilize, and Tracker), see Chapter 25, “
Image Tracking, Stabilization, and
SmoothCam ,” on page 717.
For information on the transform functions that affect image resolution (Fit, Resize, and
Zoom), see “
Nodes That Affect Image Resolution ” on page 183.
For information on cropping functions (AddBorders, Crop, Viewport, and Window), see
“
Cropping Functions ” on page 186.
CameraShake
The CameraShake node is a macro that applies noise functions to the pan values of
Move2D. Since it is a good example of how to use noise, look at the actual macro
parameters. Usually, a Scale is appended following a CameraShake node to make up for
the black edges that appear. Because of the concatenation of transformations, this does
not double-filter your image, so speed and quality are maintained.
Parameters
This node displays the following controls in the Parameters tab:
xFrequency, yFrequency
The x and y frequency of the shake. Higher numbers create faster jitter.
xAmplitude, yAmplitude
The maximum amount of pixels the element is moved by a single camera shake.
