Simply connect your Tracker node and your LensDistorsion node and hit Generate.

This node automatically copy the tracker in a new one, and each keyframe of each track will come with the new undistort position.

The core of this node is a full python

Knowing issue:

- If the track goes over the format boundaries it will return wrong track, outside that area the lensdistorsion math doesn't work because tends to infinity, but next version will comes with an overscan choise to give you a bit of more flexibility.

Next version will come with:

- Undistort/distort pulldown choise

- UVmap input as lens distorsion information

- Now works only with Tracker3 type, next will works also with new trackers4

Inside you can find also an example nuke script

Note that this is a beta version, so comments are really welcome
