• in: Maintains the frame size of the input image as that of the output image. The
result is a moving black area that encroaches around the edges of the output image.
steadyMode
The SmoothCam node has two modes: Smooth and Lock.
• Smooth: This mode smooths the apparent motion of the camera, while allowing the
general movement in the frame to proceed. It’s useful for removing jitter from a
camera movement. When enabled, this mode has three sliders for each of the
dimensions that can be smoothed.
The amount of smoothing can be increased or decreased along a sliding scale.
• translationSmooth: Smooths motion in both the X and Y dimensions.
• rotationSmooth: Smooths image rotation.
• zoomSmooth: Smooths an uneven zoom.
Note: Don’t turn on zoomSmooth unless you’re positive that the image is being
zoomed. Otherwise this parameter will not have the desired effect.
• Lock: This mode attempts to lock the motion of the principal subject in the shot to
eliminate motion. As a result, the background will appear to move around the
subject being tracked.
• InverseTransform: This control lets you invert the effect of this node, so that other
images can be matchmoved using the same motion.
• translateLock: Locks the image in both X and Y dimensions.
• rotateLock: Locks the rotation of the image.
