Two sample node like the 'Scatter' and 'Copy' node in Houdini.
Roto Centroid It tries to find out the centroid of a given rotoshape (based upon the area, NOT bounding box or average point values). It does this using an algorithm I put together in python for finding the centroid of 2d shapes based upon their point locations. This allows you to effectively find the center of mass of a Beziers etc. This differs from the center of the bounding box, or average point values in that it changes depending on how the shape is distributed, so it is unbiased on the amount of points you're using. I made this because Houdini can do this, so I felt Nuke should be able to aswell.
Analyses motion and generates a pass that can be used to drive an iDistort to mimic the motion of the source clip
A replacement for Nuke's default camera shake node -- offers more control over 3 different frequencies of camera shake, and also shakes the centre-point, giving more detail to sub-frame motionblur. Also has options for how to deal with edge-of-frame pixels, so pushing in isn't always your best option anymore!
