This blend contains a little feature called InPainting. A little known node, this filter node can fill in small gaps with great success. I've adapted it to work with larger areas as well.
It is great for: - Removing small/thin objects - Patching images you'd like to parallax animate.
I've added a blur node to progressively blur into the patch, giving an even smoother finish and this has a control exposed. Inside, you'll find the dilate and erode node, where you can adjust the progression if need be.
Use is entirely at your own risk
