You can create and manage up to four chroma key definitions from the LSM
Remote Panel, or in Epsio, using the chroma key profiles.
The various chroma key parameters allow you to define or refine a chroma key
profile.
The representation of the chroma key definition in a color space will help you
visualize the range of colors taken into account in the chroma key definition.

A YUV color space is displayed on the CHROMA tab in Epsio to represent the
color range selected in the chroma key:
The chroma key definition is represented as follows on the color space:
• The black box in the color space corresponds to the colors that are totally
removed on the chroma key layer (black).
• The colors between the black and white boxes in the color space correspond to
the transition color range, in other words to the colors that will be more or less
removed on the chroma key layer. The white box is clearly displayed in Epsio.
• The colors outside the white box in the color space correspond to the colors
that are not removed on the chroma key layer (white).

A YUV color space is displayed on the top left corner of the monitor to represent
the color range selected in the chroma key. It contains additional scales, with
‘sliders’ to reflect the hue, saturation and black level (or brightness) of the
selected color range. The grey box displayed on the color space represents the
selected color range.
