CMS CMS Audio and Video Production 2 — Questions and Answers
Question 1: What is 'B-roll' footage in video production?
- The main interview or action footage
- Supplemental footage used to cut away from the primary shot (Correct answer)
- Footage shot with a B-camera simultaneously
- Raw unedited footage from the camera
Correct answer: Supplemental footage used to cut away from the primary shot
B-roll is supplemental footage intercut with the main shot to add context, visual interest, or to cover edits.
Question 2: Which microphone pattern is best suited for capturing a single speaker in a noisy environment?
- Omnidirectional
- Cardioid
- Figure-8
- Supercardioid (Correct answer)
Correct answer: Supercardioid
A supercardioid pattern has a narrower pickup angle than cardioid, providing better off-axis noise rejection in noisy environments.
Question 3: What does '4K' resolution refer to in video production?
- 4,000 frames per second
- Approximately 4,000 pixels of horizontal resolution (Correct answer)
- 4 kilobytes of data per frame
- A 4:1 aspect ratio
Correct answer: Approximately 4,000 pixels of horizontal resolution
4K refers to a horizontal resolution of approximately 4,000 pixels, with the common UHD standard being 3,840 × 2,160 pixels.
Question 4: What is 'color grading' in post-production video work?
- Correcting exposure errors in camera settings
- The creative process of adjusting and enhancing color to achieve a specific look or mood (Correct answer)
- Matching colors between different camera brands
- Converting video from RGB to CMYK
Correct answer: The creative process of adjusting and enhancing color to achieve a specific look or mood
Color grading is a creative post-production process that manipulates color, contrast, and tone to establish a specific visual style or mood.
Question 5: Which audio recording technique captures sound from two microphones placed at 90 degrees to each other for stereo recording?
- Mid-Side (M/S)
- X/Y coincident pair (Correct answer)
- Binaural recording
- ORTF technique
Correct answer: X/Y coincident pair
The X/Y coincident pair technique uses two cardioid microphones positioned at 90 degrees, capturing a natural stereo image from a single point.
Question 6: What is the purpose of a 'LUT' (Look-Up Table) in video post-production?
- To organize timeline layers in a non-linear editor
- To map input color values to specific output color values for grading or conversion (Correct answer)
- To synchronize audio and video tracks
- To calculate rendering time estimates
Correct answer: To map input color values to specific output color values for grading or conversion
A LUT maps input color values to predetermined output values, enabling consistent color grading, log-to-display conversion, or creative looks.
