This Gizmo has multiple features to use the Cornerpin2D in way better, like single click animation in all 'to' or 'from', clear animation, Autocorner pin, copying animation from other Cornerpin2D node, Stabilize any frame, and Convert Gizmo back into default Cornerpin2D node.
Corner pin upgrade with which you can make offset in all the sides and use reference guide lines. Is implemented in nuke export options. You can export directly from the Nuke traker or Planar tracker.
Smart transforms with a very light gizmo. Without slowing down your scripts.
Sticky crop transforms a crop based on the transform input which could be any animated Transform node, Corner pin or tracker node.
Create lens distortion effects same as ARRI Ultra Prime Lenses. Can also be used to undistort source footage for 3D renderers.
Make BBox for images that don't have them
Generates two x and y positions from two ellipse shapes related to an angle you choose. the angle can be generated manually or randomly.
Uncrop to place a cropped image back in its original position, or crop to the size of the BBox.
Nuke's own cornerpin but simpler to use
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!
