B-roll is supplemental or cutaway footage intercut with the main 'A-roll' interview or primary shot to provide visual context and variety.
Question 3: What is the primary purpose of a chroma key (green screen) technique in broadcast production?
- To adjust color balance of footage in post-production
- To replace a solid color background with a different image or video (Correct answer)
- To enhance skin tones during live broadcast

Correct answer: To replace a solid color background with a different image or video
Chroma key composites two images by replacing a specific color (usually green or blue) in one layer with footage from another source.
Question 4: In non-linear editing (NLE), what does a 'sequence' represent?

- The ordered arrangement of clips on a timeline forming the edited program (Correct answer)

Correct answer: The ordered arrangement of clips on a timeline forming the edited program
A sequence is the timeline in an NLE where clips are arranged in order to create the finished edited program.

- Omnidirectional
- Figure-8 (bidirectional)
- Cardioid or supercardioid (Correct answer)

Correct answer: Cardioid or supercardioid
Cardioid and supercardioid patterns are front-focused, rejecting sounds from the sides and rear, making them ideal for isolating interview subjects in noisy environments.

- That pure white objects appear white under any lighting condition (Correct answer)
- That all video clips match the same exposure level
- That the green channel dominates in outdoor scenes

Correct answer: That pure white objects appear white under any lighting condition
White balance adjusts the camera's color temperature sensitivity so that white objects are rendered as neutral white regardless of the light source's color temperature.
