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.
Note: The following steps apply to both the HLS and Diamond Keyers.
To remove stray pixels:
- View the secondary in the Player. Press F11 to toggle between Matte view and Secondary view.
- Drag the Cleanup slider to the right to apply a median filter to remove stray pixels.
