56 Chapter 2 Major Features and New Nodes
Parameters in the SmoothCam Node
This node displays the following controls in the Parameters tab:
analysisRange
The range of frames of the input image to analyze. By default, this parameter inherits
the number of frames in the source media file represented by the FileIn node to which
it’s connected, not the timeRange in the Globals tab.
processedRange
This is not a user-editable parameter. It indicates the overall frame range that has been
analyzed.
analysisQuality
Defines the level of detail for the motion analysis. There are two levels of quality,
“normal” and “high.” In most situations, “normal” should produce an excellent result.
Should you notice any artifacts, set this parameter to “high.”
analyze
Click this button to analyze the frame range defined by the analysisRange parameter.
Pressing Esc while Shake is analyzing stops the analysis.
clipMode
The clipMode parameter provides different ways you can treat the size of the output
frame in order to include or exclude black regions introduced by the SmoothCam
node’s transformations. The clipMode parameter has three options:
• union: Expands the rendered frame to include the full area within which the input
image is transformed. If you scrub through the SmoothCam node’s output with this
option turned on, the image appears to float about within a black frame larger than
itself. The frame size of the output image is larger than that of the input image.
