Automatic Dirt Removal

The Automatic Dirt Removal plugin uses optical flow technology to target and repair temporally
unstable bits of dust, dirt, hair, tape hits, and other unwanted artifacts that last for one or two
frames and then disappear. All repairs are made while maintaining structurally consistent detail
in the underlying frame, resulting in a high quality restoration of the image. Fortunately, despite
its sophistication, this is a relatively easy plugin to use; just drop the plugin on a shot, adjust the
parameters for the best results, and watch it go.

NOTE This plugin is less successful with vertical scratches that remain in the same
position for multiple frames and is completely ineffective for dirt on the lens that
remains for the entire shot.
