What term describes the sequence that begins finished films and includes color bars, test tone, slate, and countdown?

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

Answer: (B)

The lead-in (leader) is the pre-roll sequence that starts finished films, and it includes color bars, a test tone, a slate, and a countdown to cue the start. Color bars provide a quick way to calibrate picture quality across monitors and equipment. The test tone ensures audio levels are properly calibrated before the program begins. The countdown gives a precise signal to synchronize playback and let operators know when the program will start. The slate offers identification and helps with syncing audio and video data. Taken together, this pre-roll sequence prepares both the viewing systems and the crew for a smooth start, which is why this term is the best fit. A test pattern focuses only on video calibration, a countdown is only part of the sequence, and a slate is just one component; none alone captures the full pre-start package.
