'lp_' is not really the name inside of Nuke, it's more for organizing on a server/computer harddrive


A simple tool to give your CornerPins a reference frame. Well not exacly: this tool is fed with an image and CornerPin-data and will then do the rest. I decided against adding the functionality directly to a CornerPin with Python for workflow reasons. An advantage is that you can replace the CornerPin-data at any time and it doesn't interfere at all with the initial setup of your image data.

Don't bother with setting up the planar surface in Mocha; after the third time I got nan-values pushing it in the corners, I came up with this tool. You just track, copy the CornerPin-data and place it into Nuke, nothing more :)

Of course it concatenates and gives you the choice of matchmoving or stabilizing.


For a better understanding, here an example how you would set it up for a screen insert:




You set up your insert on your desired reference frame as you need it, e.g. with a CornerPin. Directly after, you put ReferencePin with your CornerPin data connected and the correct reference frame - and you are done. At any time you can replace the CornerPin and because the reference frame stays the same, only your track will change, not your setup.

Another benefit is that you can fix tracking issues by animating your setup-CornerPin rather than the track itself.

You can also use the same CornerPin-track to first matchmove and then stabilize your footage again, even though it is not recommended because of the filter hits.


Update v2.0
(v1.0 was never released)
- re-worked the connection of CornerPin-data so a dot (or any other node) won't break the Expressions (thanks to Frank Rueter and Erwan Leroy for the help on this one!)

This tool is a Group, not a Gizmo; edit if needed. I only checked if it works in 11 and 7.0v9, as it's rather simple I assumed it will work in anything in between :)
