Chroma and luma keying – selecting the keying mode

Click on the highlighted square button Mode to choose the keying mode.

There is a choice between four options:

  • Chroma Key – precise setting of the key,
  • Simple Chroma Key – quick setting of the key,
  • Luma Key – setting of the key on the basis of luminance,
  • Disable Key – working with the key off.

Chroma and luma keying

Keying is a special filter that in the Reckeen 3D Studio system can be used for camera inputs. The principal of its operation is to remove the areas of a specific color (e.g. green) from the image. The green color is removed after you turn the keying on and set its parameters. This way a figure of a presenter filmed on a green background can be placed against any virtual decoration.

The key can operate in either luminance (luma-keying) or chrominance (chroma-keying) mode. Setting the parameters of the key is done in a few simple steps, through which a special wizard can lead you. Thanks to this solution, selection of optimal key parameters is achievable even for the inexperienced users. And the results are impressive.
