What is the segment at the beginning of a master tape that contains color bars, test tone, slate, and black or countdown called?

• A. Slate
• B. Leader
• C. Index
• D. Preview tape

Answer: (B)

That segment at the start of a master tape is the leader. It exists to calibrate and synchronize equipment before the program content begins. The color bars provide a reference for video color and brightness; the test tone checks and calibrates audio levels; the slate gives a visual and audio cue for take identification and synchronization; the black or countdown frames indicate the exact moment to start. These functions help ensure correct broadcast quality and precise timing when the tape is played back or edited. The other terms refer to different concepts: a slate is the marker used during production, not the lead-in segment; an index relates to cueing on the tape; a preview tape is a separate recording used for reviewing material.
