Adjust Chroma Key Object Properties

When a chroma key layer is applied to an effect production element, for example a mix or other background (created in GV Director Composer), the GV Director system provides runtime adjustment of chroma key values to improve the quality of the key for lighting and consistency of the matte (environment can affect the chroma key for example in a dynamic environment with live inputs, changing light, and possibly a subject in front of a green screen).

1. Tap Effects .
2. Double-tap, hold, and drag a production element button.

   

3. Drag out from the production element button to display the radial menu and release when Properties is highlighted.

   

4. Touch to select Blue or Green key color.

   

5. Touch, hold, and move a slider to control:
   • Edge Offset: increase or descrease the distance between the subject and the chroma key
   • Edge Smoothness: increase or decrease edge smoothness
   • Split Suppression: increase or decrease the split suppression of the subject background; prevents the background from spilling onto the subject
   • Light Wrap: increase or decrease spill of the background (a keyed background) onto the subject
