Chapter 4 Video Recording and Color Grading — Image quality adjustment
[CHROMA]
This function sets color saturation and phase in [MENU] → [SCENE FILE SETTINGS] → [CHROMA].
The effect is applied to the entire video. It cannot be set for individual color hues.
f
[LEVEL]: Sets the chroma level of the P
R
and P
B
signals. The distance from the center (no color) increases or decreases the effect for the entire video
when vector scope is used.
f
[CHROMA PHASE]: Finely adjusts the chroma phase of P
R
and P
B
signals. The entire video rotates clockwise or counter-clockwise when vector scope
is used.
[MATRIX]
The color representation of the video can be set by changing the setting value relatively against the matrix table that will select the optimal setting
automatically against the gamma setting.
If the settings are changed, the representation of all the colors in the video will also be changed.
The color representation will differ when the set matrix table is different even if the value is the same since it is a relative adjustment.
