This option 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.
You can use one of the above three clipMode options to produce the output image
most useful for your purposes.
Note: Whichever clipMode you use, areas of the image that end up being clipped are
preserved by Shake’s Infinite Workspace, available for future operations.
Scaling the Output Image to Fit the Original Frame Size
If you need to output the resulting image at the same size as the original, the quickest
fix is to leave the clipMode Parameter set to “in, “ and use a Scale node after the
SmoothCam node to enlarge the image to the point where all instances of black
borders fall outside the edge of the frame. The disadvantage of this method is the
resulting softening of the image, depending on how much it must be enlarged.
Painting the Edges Back In
A more time intensive, but possibly higher-quality solution would be to paint the
missing edge data with a QuickPaint node. A variety of techniques can be employed,
including using the clone brush to sample other parts of the image, or using the Reveal
Brush to paint in parts of a secondary clean-plate image that you create separately.
Warping the Edges
One last suggestion would be to experiment with the different warping nodes, to
stretch the edges of the image to fill any gaps. For example, you can experiment with
the LensWarp node to stretch the edges of the image out. This solution is highly
dependent on the type of image, and may introduce other image artifacts that may or
may not be acceptable.
