In the Ultra Key effect, what is the purpose of the eyedropper tool?

• A. To sample the color you want to remove from the footage.
• B. To adjust the overall brightness of the clip.
• C. To sample the key color from the footage.
• D. To toggle Ultra Key on and off.

Answer: (C)

Sampling the key color from the footage is what the eyedropper does. In Ultra Key, you define what color to remove by picking a pixel from your clip that represents that color (for example, the green screen). That sampled color becomes the reference the keyer uses to identify and remove the background. Once you’ve sampled a color, you can fine-tune how closely similar colors are treated and manage edges and spill to clean up the key. The eyedropper isn’t for brightness adjustments or toggling the effect—that’s handled by other controls. The essential idea is that the eyedropper sets the exact color you want to key out by sampling it directly from the footage.
