Pixel Spread is included in our FlameFX toolset, and is a great technical tool that allows you to address multiple issues. In this video I cover 4 typical scenarios for which Pixel Spread can be a major helper in your workflows:
Fixing bad edges on a key
Pixel based warping with a traveling alpha channel
Working with pre-multiplied graphics with CGI-compositing
Accurate pixel warping with a vector map (different from normal displacement)
There are many other uses of pixel spread, which I am still looking into, so I'll keep those for another video…
