The following procedure is a recommended workflow for keying a clip with the Master Keyer. You may not
need to complete all the procedures. You may also revisit procedures as you develop the key.
To create a complete key:
1 Generate and refine a matte using the Matte controls.
2 Remove any colour spill.
3 Improve the blend between the front and back clips.
4 If the image is grainy, apply the Degrain algorithm.
5 Create any necessary patches to remove unwanted grey areas from the matte.
Generating Mattes
Use the Matte controls in the Master Keyer to generate and refine a matte for your chroma key.
To generate and refine a matte:
1 In the Master Keyer menu, select Matte from the Sampling box.
2 Set the view to Result or Matte view.
3 Click the Primary Sample colour pot and then sample the image. Click the image to sample a single
pixel.
The Auto CC button is enabled and the initial pure colour value for the key is set.
4 Click the Secondary Sample colour pot and then sample the image. Sample an area where you do not
want any softness in the matte.
5 Drag in the Mix field to adjust the mix between the primary and secondary sample. Drag right to
include more of the secondary sample or left to include less.
