Parameters in the Camera Tab
All of the parameters that affect the camera are located within the Camera tab of the
parameters.
renderCamera
A pop-up menu that lets you choose which angle provides the output image from the
MultiPlane node.
Lock, Unlock, Reset
Click the Lock button to lock all of the camera parameters at once, preventing them
from being accidentally edited. Click the Unlock button to unlock these parameters
again. Click the Reset button to restore the camera to its default position.
cameraName
A text field that lets you rename the camera or angle to more accurately describe your
setup.
sceneScale
Scales the depth of the virtual space used to distribute the locator points that are
displayed in the Viewer (which represent 3D tracking data clouds imported from .ma
files). This parameter allows you to expand or compress the relative distance from the
camera to the tracked background plate. Adjusting this parameter lets you more easily
position layers in space when camera tracking data comes from a subject that’s either
very far away, or very close. This parameter is for reference only, and has no effect on
the data itself. The default multiPlaneLocatorScale value is 50.
Camera Transform Data
The following parameters contain transform data for the camera, as well as parameters
that determine how the image is resolved based on mathematically simulated camera
attributes such as focal length and film gate resolution. These parameters are adjusted
whether you simply reposition the camera within the 3D workspace, keyframe the
camera manually, or import a camera path or 3D tracking data from a .ma file.
Note: Many of the parameters found within the Camera tab are identical to parameters
exported by Maya. For more information, see the Maya documentation.
Lock, Unlock, Reset
Three buttons let you lock all camera parameters, unlock all camera parameters, or
reset all camera parameters.
focalLength
Sets the focal length of the camera’s virtual lens. Shake measures the focal length in
millimeters. The default focalLength is 35mm.
