Once you have set the tolerance range, you can then set the softness range. Softness sets the range of colours to make semi-transparent and creates a softer key. Use softness to create a more natural and softer look when applying secondary colour correction.

To set the chrominance range for softness, you can manipulate the chrominance Softness Diamond. You can use the Add Softness and Remove Softness buttons to set the chrominance range and luminance levels for softness. You can also use the Minimum and Maximum Luminance sliders to set the luminance levels for softness.

To set the chrominance range for softness by moving and modifying the Softness Diamond:

1. View the secondary in the Player. Press F11 to toggle to Secondary view.

   In Secondary view, you can see the effect of the modifications you make while you fine-tune the key.

2. Click and drag the Softness Diamond or click and drag a vertex of the Softness Diamond.
   NoteIf the Softness Diamond vertex is too small to drag with the mouse, you can use the scale and skew controls to expand the diamond. See Using the Scale and Skew Controls in the Diamond Keyer. You can also zoom in or out on the hue cube. Right-click and drag to the right to zoom in or drag to the left to zoom out. The Softness Diamond is red when selected and grey when unselected.
