When you extract a key, pixels in other parts of the image may be included. You can remove these stray pixels from the key to clean it up for colour grading.

NoteThe following steps apply to both the HLS and Diamond Keyers.

To remove stray pixels:

1. View the secondary in the Player. Press F11 to toggle between Matte view and Secondary view.
2. Drag the Cleanup slider to the right to apply a median filter to remove stray pixels.
