In the Effect Controls panel:
- Matte scales the pull from the frame’s own corners per pixel, read where the pixel lands: white moves it all the way to the pinned position, grey part way, black leaves it where it was. Invert reads that matte inverted.
What each control does
Section titled “What each control does”- Upper left, Upper right, Lower left, Lower right set the position of the four corners.
- Edges decides what fills the area a corner has been dragged away from. Transparent leaves it empty. Repeat smears the border pixel outward and Mirror reflects the picture back.
- Mix: how much of the result replaces the original.
- Matte and Invert drive the strength of the effect from another layer’s brightness; see Effects.
