User Manual

For a simple over-the-shoulder graphic, masking the image may be all you need to do, but
masking an image does not change the actual dimensions of the graphic. It only changes the
area you see. So, accurately positioning the graphic based on the center of the composite
becomes more difficult, and any type of match moving would give incorrect results because the
graphic has a different resolution than the background. To fix this resolution mismatch, you can
place a Crop node after the MediaIn to change the actual dimensions of the graphic layer.
Adding a Crop node after the masked MediaIn to center the cropped logo on the background.
With the Crop node selected, the viewer toolbar includes a Crop tool.
Selecting the crop tool in the viewer toolbar.
You can crop the image by dragging a bounding box around it. Unlike a mask which creates a
small window you view the image through, a crop effectively changes the resolution of the
graphic to the crop bounding box size.
Dragging a bounding box using the Crop tool (left), and the cropped logo now centered on the frame (right).
NOTE: The Resize, Letterbox, and Scale nodes also change the resolution of an image.
