After you remove colour spill,
you can use the Blend parameters to gesturally modify the luminance
at the edge of the key so that it blends with the luminance in the
background clip. For example, when the front clip is darker than
the back clip, you can use the Blend parameters to lighten the edge
of the key. You can also use the Blend controls in the Keyer or
Colour menu. For instructions on using Blend controls, see
Blending the Front and Back Clip.
When you blend front
and back clips, you can add a cast to the edge of the key and further
integrate the clips.
NoteTo blend front and
back clips in the Master Keyer menu, the Auto CC button must be
enabled.
To blend the front and back clips:
- In the Master Keyer menu, select Blend
from the Sampling box (or press B).
- Set the view to Result view.
- Enable Auto CC to apply the Spill settings
to the front clip.
- Blend the front and back clip. Click
anywhere in the image window, and then modify the parameters that
appear by dragging the sliders—you do not need to click
a specific area.
Drag: |
To: |
Luma |
Darken or lighten the edge of the key. Luma only affects
the luma of the edge.
|
Edge Size |
Set the range for the blend. Drag right to soften the
edge and blend further into the key. Drag left to harden, or create
a thinner, edge. Edge Size affects both the Luma field and the Edge
Balance trackball.

TipTo drag faster, apply
more pressure with the pen, or right-click the mouse while you drag.
The red indicator shows
the original value and the yellow indicator shows the current value.
The values also appear in the Blend fields.
- To modify both parameters, move the mouse
between them to highlight a parameter, or drag the pen vertically.
When you highlight the parameter you want to adjust, drag the slider.
TipIf you do not like
the result, you can click Undo to reset parameters directly after
you complete an operation. There is only one level of undo in the
Keyer menu.
- When you are finished modifying the displayed
parameters, click another area of the image without highlighting
a parameter to hide them. Alternatively, you can press any key,
such as spacebar or Esc.
The parameters are no
longer displayed.
- To add a cast to the edge of the key
and improve the overall look by matching the edge with a colour
cast in the back clip, drag the Edge Balance trackball toward the
colour you want to add. The trackball only affects the chroma of
the edge.
NoteTo reset Blend parameters,
click the Reset button, next to the sampling box. All blend parameters
are reset, except the Edge Balance trackball. Ctrl-click the Edge Balance trackball
to reset it. Alternatively, you can reset the Spill parameters,
Blend parameters, and the Edge Balance trackball by clicking Reset,
located left of the Edge Balance trackball.
