Tutorial 9 Creating Clean Plates 247
This image is attached to the first input of the AutoAlign1 node, and is designated as
the “locked” plate—meaning that it will not be distorted.
From the lockedPlate list, you can choose an alternate image and the other images will
be distorted to match it.
Stabilizing and Stitching Background Plates
AutoAlign also stitches moving images. In this section, the process is almost identical to
the previous example, except you will first stabilize the images to eliminate unwanted
movement. You will open an existing script, stabilize the images with the SmoothCam
node, then stitch them together with AutoAlign.
Note: If you do not stabilize your footage before using AutoAlign, then the images
should be matched to the movement of the image specified as the “locked plate.”
