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.

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