Captura de pantalla 2023-10-23 204455 lp2DPMatte v1.1 is a blinkscript gizmo that calculates and bakes the center of an alpha in every frame. With the center, this gizmo allows you to move the shape that is painted in the center of the alpha to any point of the frame moving that shape with the same transforms that the center experience. It also lets you export this tracking data to a match-move, or a stabilize transform node.

First of all, you'll need to bake the center position, it will process the number of frames that you select. After that with the viewer in the lp2DPMatte something like this will appear:

With this you'll be able to move the shape to any point and it will move like the default shape position in the new selected position. You can also export all this track data to a match-move node, or a stabilize one!


I want to thank the YouTube channel Nodes Aren't Scary https://www.youtube.com/@nodesarentscary and his The Power Of BlinkScript (Nuke) video https://www.youtube.com/watch?v=Wru4IDfV4EU for giving me the idea to do this node. Thanks mate!

This is my first update, so I will apreciate any suggestions to the node or any ideas that you post in comments. I have some, but I don't have too much time!
