Using the Blue Screen and Green Screen keys

The Blue Screen and Green Screen keys create transparency from true chroma blue and true chroma green. Use these keys to key out well-lit blue or green screens when creating composites.

Adjust the following Blue Screen and Green Screen key settings as necessary:

Threshold Drag to the left until the blue or green screen is made transparent.

Cutoff Drag to the right until the opaque area reaches a satisfactory level.

To fine-tune edges, drag Threshold and Cutoff sliders in small increments.
