In the Effect Controls panel:
- Matte is the displacement map: the chosen channels of the matte layer say which way and how far each pixel is pushed, mid-grey meaning no push at all — the effect’s subject rather than a strength applied to one. Invert reads that matte inverted.
What each control does
Section titled “What each control does”- Matte is the map, and is required for the effect to change anything.
- Horizontal channel and Vertical channel choose the channel used to scale each direction.
- Horizontal amount and Vertical amount adjust the scaling multiplier.
- Edges adjusts what resulting transparent pixels are filled with. Repeat smears the border pixel and keeps the frame full. Transparent fills with nothing. Mirror reflects the picture back.
- Mix: how much of the result replaces the original.
- Invert reads the map the other way round.
