Invert a key when it is easier to exclude rather than include colours in a secondary.
NoteThe following steps apply to both the HLS and the Diamond Keyers.
To invert a key:
- In the Secondaries menu, toggle the Matte/Key-in option box to display the Key Invert panel, and then enable Invert.
The area of the key that was opaque becomes transparent and the area that was transparent becomes opaque.
