Adjusting the chroma key shadow
This function allows a shadow falling on the (typically blue) background color to be rendered more realistically. Since portions of the (blue) background of less than a certain luminance are treated as shadows, there is no effect on cutting out of the foreground.
Use the following procedure.
1 In the Chroma Adjust menu, set [Shadow] on.
2 Adjust the following parameters.
Knob | Parameter | Adjustment | Setting values |
|
|
|
|
1 | Luminance | Reference luminance for shadows | 0.00 to 100.00 |
|
|
|
|
2 | Gain | Shadow key gain | −100.00 to +100.00 |
|
|
|
|
3 | Density | Shadow opacity | 0.00 to 100.00 |
|
|
|
|
4 | Soft | Shadow softness | 0.00 to 100.00 |
|
|
|

Note
When chroma key shadow is on, key edge is changed to normal, and soft edge is switched off.
