What term refers to the color bars and test tone used to calibrate video equipment?

• A. Slate
• B. Test Pattern
• C. Leader
• D. Countdown

Answer: (B)

A test pattern refers to the sequence of color bars, grayscale steps, and often a tone used to calibrate video equipment. It provides a known reference so technicians can set color accuracy, brightness/contrast, gamma, and audio levels, ensuring consistent rendering across displays and devices. This is why it’s the best choice: its purpose is specifically to provide those standard reference signals for setup and verification. A slate identifies takes, a leader is the pre-roll portion of the program, and a countdown is part of that pre-roll; none of these are used for calibration, only for production timing and organization.
