When a 2D tracker with a four point track is completed, you can simply enter the name of the tracker in this gizmo and provided you have the gizmo attached underneath your foreground element followed by a merge over the background, the corner pin will be applied automatically. The aspect ratio of the foreground image will be maintained and the image will be cropped accordingly. You can decide which frame to use as reference for when cropping the image by entering the frame number you choose in the relevant field.
There is a transform dropdown which enables modifications to be made for the foreground images placement within the four point tracking area. There is also a motion blur dropdown which enables the user to modify the motion blur settings for the cornerpinned element.
If you do require a standard cornerpin result, you can select 'Standard CornerPin' from a dropdown. This will then give you the standard cornerpin effect and also links to the tracker automatically provided you have entered the name of the tracker in the relevant field.
I hope you find it useful!
