Question 1Media Production

Which camera setting controls how much light reaches the sensor by adjusting the size of the lens opening?

  1. White balance
  2. Shutter speed
  3. ISO
  4. Aperture Correct answer.

Explanation

Aperture is the adjustable opening in the lens, and its f-number describes how wide that opening is. A smaller f-number means a larger opening and more light reaching the sensor. The other settings manage exposure time, sensitivity, or color, not the physical opening size.

Question 2Media Production

A videographer wants shallow depth of field to isolate a subject. Which change best achieves this?

  1. Use a narrower aperture such as f/16
  2. Raise the ISO to the maximum value
  3. Use a wider aperture such as f/2.0 Correct answer.
  4. Increase the shutter angle to 360 degrees

Explanation

Depth of field shrinks as the aperture opening grows wider, which corresponds to a lower f-number. A setting like f/2.0 therefore blurs the background more than f/16. Shutter angle and ISO affect motion rendering and brightness, not the depth of field.

Question 3Media Production

In the standard three-point lighting setup, what is the primary purpose of the fill light?

  1. To illuminate the backdrop evenly
  2. To separate the subject from the background
  3. To create a hard rim of light on the hair
  4. To soften shadows created by the key light Correct answer.

Explanation

The fill light sits opposite the key light and reduces the contrast of the shadows the key creates. It is usually softer and dimmer than the key so some modeling remains. Separation and rim effects come from back or hair lights, and backdrop lighting is a separate concern.

Question 4Media Production

Which microphone polar pattern picks up sound mostly from the front while rejecting the rear, making it common for dialogue recording?

  1. Figure-eight
  2. Omnidirectional
  3. Boundary
  4. Cardioid Correct answer.

Explanation

A cardioid pattern is most sensitive at the front and least sensitive at the rear. This directional behavior helps isolate a speaker from surrounding noise. Omnidirectional patterns capture all directions, and figure-eight favors front and rear while rejecting the sides.

Question 5Media Production

A recorder captures dialogue peaking near 0 dBFS with occasional clipping. What is the best corrective practice?

  1. Enable a low-cut filter to remove clipping
  2. Lower the input gain so peaks sit around -12 to -6 dBFS Correct answer.
  3. Raise the gain further to improve signal clarity
  4. Switch the recorder to a higher sample rate

Explanation

Digital clipping occurs when the signal exceeds the maximum level the system can represent. Leaving headroom by targeting peaks well below 0 dBFS prevents distortion and allows later mixing. Sample rate and filtering do not repair an overloaded signal.

Question 6Media Production

Which editing technique cuts directly between two shots of the same subject from different angles to keep a conversation flowing?

  1. Shot-reverse-shot editing Correct answer.
  2. Jump cut
  3. Match on action
  4. Cross-dissolve

Explanation

Shot-reverse-shot alternates between opposing camera angles, typically over each speaker's shoulder. This maintains continuity and keeps dialogue scenes visually dynamic. A dissolve blends images, a match on action links movement across cuts, and a jump cut creates a deliberate discontinuity.

Question 7Media Production

What does the 180-degree rule govern in film production?

  1. Setting the shutter angle to 180 degrees for natural motion
  2. Restricting shots to no more than 180 frames
  3. Limiting each scene to a half-circle of camera movement
  4. Keeping the camera on one side of an imaginary line to preserve screen direction Correct answer.

Explanation

The 180-degree rule keeps the camera on one side of an imaginary axis between subjects. Staying on that side preserves consistent left-right screen direction across cuts. Crossing the line can make characters appear to swap positions and disorient the viewer.

Question 8Media Production

A scene is shot at 24 frames per second. Which shutter speed gives the traditional cinematic motion blur?

  1. 1/1000 second
  2. 1/12 second
  3. 1/48 second Correct answer.
  4. 1/24 second

Explanation

The classic rule doubles the frame rate to find the shutter speed, producing a 180-degree shutter angle. At 24 fps that yields 1/48 second, which renders natural-looking motion blur. Other values either smear motion excessively or freeze it too crisply.

Question 9Media Production

Which file format is most appropriate for delivering a finished video to a client for general playback?

  1. PSD layered image
  2. MP4 using H.264 compression Correct answer.
  3. CSV spreadsheet
  4. WAV audio

Explanation

MP4 with H.264 is a widely supported delivery format that balances quality and file size. It plays on most devices and platforms without special software. The other formats serve audio, image editing, or data purposes and are not video delivery containers.

Question 10Media Production

In a video editing timeline, what does a J-cut describe?

  1. Two clips are joined with a soft dissolve
  2. Audio from the next scene begins before its picture appears Correct answer.
  3. A clip is sped up to compress time
  4. The picture cuts before the previous audio ends

Explanation

A J-cut brings the incoming scene's audio in ahead of its visual, so the sound leads the picture. It is often used to foreshadow a location or smooth a transition. The reverse arrangement, where audio trails the picture, is called an L-cut.

Question 11Media Production

Which color grading operation corrects a shot so that a white object in the scene appears neutral?

  1. White balance correction Correct answer.
  2. Sharpening
  3. Vignette addition
  4. Saturation boost

Explanation

White balance correction neutralizes color casts so that objects that should be white render without a tint. It usually involves adjusting the balance between warm and cool channels. Saturation, vignetting, and sharpening change intensity or edge contrast rather than neutrality.

Question 12Media Production

A producer needs to record a wide stereo image of an orchestra from a distance. Which microphone type is best suited?

  1. A stereo condenser pair in an XY or ORTF arrangement Correct answer.
  2. A contact pickup on one instrument
  3. A handheld dynamic vocal microphone
  4. A lavalier clipped to a single performer

Explanation

A matched condenser pair arranged in XY or ORTF captures a coherent stereo image of an ensemble. Condensers are sensitive and detailed, suiting distant orchestral capture. Dynamic vocal mics, lavaliers, and contact pickups are designed for close or single-source use.

Question 13Media Production

What is the main function of a clapperboard on a film set?

  1. To record the director's camera moves
  2. To hold the script during rehearsals
  3. To measure the exposure of each take
  4. To synchronize picture and audio in post-production Correct answer.

Explanation

The clapperboard marks each take and provides a sharp visual and audible sync point. Editors align the clap with the audio spike to synchronize separately recorded sound. It also carries scene and take information for logging, but not exposure measurement or camera movement recording.

Question 14Media Production

A director wants to convey a character's isolation. Which compositional choice best supports that idea?

  1. Placing the subject small within a large negative space Correct answer.
  2. Increasing background clutter around the subject
  3. Filling the frame with a centered close-up
  4. Using symmetrical framing with the subject at center

Explanation

Negative space around a small figure emphasizes separation and vulnerability. The imbalance visually communicates that the character is alone or overwhelmed. Centered close-ups and symmetry suggest stability, while clutter adds context rather than isolation.

Question 15Media Production

Which codec is commonly used for web streaming because it delivers good quality at low bitrates?

  1. Uncompressed AVI
  2. H.264 Correct answer.
  3. ProRes 4444
  4. DPX

Explanation

H.264 is an efficient delivery codec widely supported by browsers and streaming platforms. It achieves acceptable quality at relatively low bitrates. ProRes, uncompressed AVI, and DPX are high-bandwidth formats used for editing or archival work.

Question 16Media Production

A sound designer wants to make a room feel larger in a scene. Which processing approach best achieves this?

  1. Applying a high-pass filter to remove low frequencies
  2. Adding a longer reverb tail with more early reflections Correct answer.
  3. Compressing the dialogue heavily
  4. Reducing the sample rate of the audio

Explanation

Larger spaces produce longer reverberation and more early reflections before the tail. Adding reverb with those characteristics simulates a bigger room. Filtering, compression, and sample rate changes alter tone or dynamics but not perceived room size.

Question 17Media Production

In a screenplay, what does the abbreviation V.O. indicate?

  1. A visual effect added in post-production
  2. Voice-over heard by the audience but not by characters in the scene Correct answer.
  3. A scene set outdoors
  4. A camera move toward the subject

Explanation

V.O. stands for voice-over, narration or thoughts heard by the audience but not by on-screen characters. It is distinct from O.S., which marks dialogue spoken off-screen but audible within the scene. The abbreviation does not describe effects, locations, or camera movement.

Question 18Media Production

A production must shoot a dialogue scene in a room with a loud refrigerator hum. What is the best on-set solution?

  1. Use a wide shot to reduce the noise
  2. Turn off the appliance and record clean dialogue Correct answer.
  3. Apply noise reduction later without changing the set
  4. Raise the microphone gain to overpower the hum

Explanation

Eliminating the noise source at the source produces the cleanest recording and avoids costly repair. Noise reduction in post can degrade dialogue and is best reserved for small problems. Gain changes and shot size do not remove the hum from the audio.

Question 19Media Production

Which factor most directly determines the frame rate needed to capture smooth motion of a fast-moving subject?

  1. The color temperature of the lighting
  2. The focal length of the lens only
  3. The aspect ratio of the delivery
  4. The speed of the subject and the intended playback rate Correct answer.

Explanation

Capturing fast motion smoothly requires a frame rate high enough relative to the subject's speed and the intended playback speed. Higher frame rates sample motion more frequently, reducing judder. Color temperature, focal length alone, and aspect ratio do not determine temporal sampling.

Question 20Media Production

A producer is choosing between shooting at a high frame rate for slow motion and a standard rate. What is the main trade-off?

  1. Higher frame rates improve low-light performance automatically
  2. Higher frame rates eliminate the need for proper exposure
  3. Higher frame rates capture smoother slow motion but require more light and storage Correct answer.
  4. Higher frame rates reduce storage needs but limit color depth

Explanation

Shooting at a high frame rate gives more temporal samples for smooth slow motion, but each second contains more frames and often a shorter exposure per frame. That increases storage and lighting demands. It does not improve low-light performance or remove exposure requirements.

Question 21Media Production

Which editing decision best preserves spatial continuity when cutting between two characters facing each other?

  1. Keeping both cameras on the same side of the action line Correct answer.
  2. Alternating cameras across the action line each cut
  3. Using a different lens for every shot
  4. Cutting to a wide shot after every line

Explanation

Maintaining camera placement on one side of the action line keeps each character consistently oriented on screen. Crossing the line causes them to appear to switch sides. Lens changes and frequent wide shots do not resolve that spatial confusion.

Question 22Media Production

A documentary crew must record an interview outdoors on a windy day. Which combination best improves dialogue clarity?

  1. A contact pickup attached to the chair
  2. A single camera-mounted mic at high gain
  3. Two omnidirectional mics placed far from the subject
  4. A lavalier with a windscreen plus a directional mic with a blimp Correct answer.

Explanation

Wind protection such as a windscreen and blimp reduces wind noise while directional and lavalier mics stay close to the speaker. This yields clearer dialogue in outdoor conditions. Distant omni mics and camera-mounted mics pick up more ambient wind and room noise.

Question 23Media Production

What is the purpose of a storyboard in pre-production?

  1. To record final audio mixes
  2. To plan shots visually before filming begins Correct answer.
  3. To log the budget for post-production
  4. To store the finished edit

Explanation

A storyboard is a sequence of sketches that plans framing, camera angles, and action before shooting. It helps the crew align on visual intent and saves time on set. It is not used for audio mixing, budgeting, or storing the final edit.

Question 24Media Production

Which practice best protects media files during a multi-day shoot?

  1. Storing all footage on a single laptop
  2. Backing up footage to a second drive and verifying checksums Correct answer.
  3. Renaming files without logging their contents
  4. Deleting cards after each day to free space

Explanation

Redundant backups combined with checksum verification confirm that copies are intact. This guards against drive failure and corruption during production. Deleting cards early, relying on one device, or renaming without logs risks permanent data loss.

Question 25Media Production

A colorist notices that skin tones look green under office fluorescents. Which correction is most appropriate?

  1. Increase the frame rate during grading
  2. Increase contrast to hide the green
  3. Adjust the tint toward magenta to neutralize the green cast Correct answer.
  4. Add a vignette around the subject

Explanation

Fluorescent sources often produce a green cast that is corrected by shifting tint toward magenta. Balancing tint restores natural skin tones before creative grading. Contrast, vignettes, and frame rate do not neutralize a color cast.

Question 26Media Production

Which microphone polar pattern picks up sound mainly from the front while rejecting most sound arriving from directly behind?

  1. Figure-eight
  2. Omnidirectional
  3. Cardioid Correct answer.
  4. Boundary

Explanation

A cardioid pattern is most sensitive at the front axis and rolls off progressively toward the rear, which is why it is the standard choice for isolating a single voice. Omnidirectional patterns accept sound from all directions, and figure-eight rejects the sides rather than the rear.

Question 27Media Production

In a three-point lighting setup, what is the primary job of the fill light?

  1. To raise the overall exposure of the entire set
  2. To create a bright rim along the subject's shoulders
  3. To soften the shadows cast by the key light Correct answer.
  4. To light the background separately from the subject

Explanation

The fill light sits opposite the key and reduces the contrast of the shadows the key creates, controlling how dramatic the subject looks. Its intensity relative to the key establishes the lighting ratio. Rim and background lights serve separate, distinct purposes.

Question 28Media Production

What does a shot list primarily provide to the crew on a shooting day?

  1. A record of every camera setting used for each take
  2. A log of the audio files recorded on set
  3. A breakdown of each required shot with its framing and notes Correct answer.
  4. A schedule of actor availability across the production

Explanation

A shot list enumerates the individual shots a director intends to capture, usually noting size, angle, movement, and any special requirements. It keeps the crew aligned on coverage so nothing is missed before moving on. Camera settings and audio logs are recorded elsewhere.

Question 29Media Production

Which camera setting change makes the background of a portrait blurrier while keeping the subject sharp?

  1. Switching from a wide lens to a wider lens
  2. Raising the ISO while lowering shutter speed
  3. Decreasing the f-number toward f/2 Correct answer.
  4. Increasing the f-number toward f/16

Explanation

A lower f-number opens the aperture, which narrows the depth of field so the background falls out of focus. Raising the f-number does the reverse and deepens focus. Focal length and subject distance also affect blur, but a wider lens would reduce it.

Question 30Media Production

What is the standard purpose of room tone during post-production?

  1. To replace unusable dialogue with a studio re-recording
  2. To fill gaps between dialogue edits with matching ambience Correct answer.
  3. To mask the sound of the clapperboard snapping
  4. To provide a musical bed under the dialogue

Explanation

Room tone is a recording of the location's ambient silence with no one speaking. Editors lay it under cuts so that the background noise floor stays continuous and dialogue edits do not pop or drop out. It is not music, and it does not substitute for dialogue replacement.

Question 31Media Production

A producer needs a rough cut reviewed by a remote collaborator who has slow internet. Which export choice best serves that review?

  1. A project file containing only edit decisions
  2. An uncompressed master file at full resolution
  3. A sequence of individual raw camera clips
  4. A low-bitrate proxy file with a visible timecode burn-in Correct answer.

Explanation

A lightweight proxy with burned-in timecode lets a reviewer watch smoothly on a weak connection and cite exact frames for notes. Full-resolution masters are too large to transfer quickly, and raw clips or project files are not viewable deliverables.

Question 32Media Production

Which on-set document tells cast and crew their call time, location, and scenes for a given day?

  1. The call sheet Correct answer.
  2. The release form
  3. The script breakdown sheet
  4. The continuity log

Explanation

The call sheet is the daily operational document distributed before each shooting day. It lists call times, addresses, contact numbers, scenes, and logistics for everyone involved. Breakdown sheets analyze the script, and continuity logs track scene details across takes.

Question 33Media Production

Which practice best reduces the risk of losing footage from a day's shoot?

  1. Storing a single backup drive in the same bag as the camera
  2. Keeping all cards in the camera until the project wraps
  3. Copying cards to two separate drives and verifying the transfer Correct answer.
  4. Deleting cards only after the director approves the footage

Explanation

The accepted safeguard is redundancy: duplicate the media to at least two independent destinations and confirm checksums before reformatting a card. Keeping cards in the camera or holding a single backup leaves one failure point. Verification matters as much as the copy itself.

Question 34Media Production

A scene is meant to feel uneasy, so the director asks for the subject placed low in the frame with a large empty area above. Which principle is being applied?

  1. Over-the-shoulder framing
  2. Headroom as a psychological tool Correct answer.
  3. Rule of thirds balance
  4. Leading-room continuity

Explanation

Headroom is the space between the subject's head and the top of the frame. Excessive headroom can make a subject feel small, trapped, or anxious, which is why it is used deliberately for mood. The rule of thirds is a compositional guideline, not a mood device by itself.

Question 35Media Production

An editor needs a dissolve between two clips to last exactly 30 frames at 24 fps. How long is that transition in seconds?

  1. 2.0 seconds
  2. 0.75 seconds
  3. 1.5 seconds
  4. 1.25 seconds Correct answer.

Explanation

Divide the frame count by the frame rate: 30 frames divided by 24 frames per second equals 1.25 seconds. This conversion is essential when a director specifies a duration in frames but the timeline reports seconds.

Question 36Media Production

Which audio tool is most appropriate for removing a steady 60 Hz electrical hum from a dialogue recording?

  1. A short reverb effect
  2. A broadband compressor
  3. A pitch shifter
  4. A notch filter at the fundamental and its harmonics Correct answer.

Explanation

Hum from mains power sits at a fixed low frequency plus harmonic multiples, so narrow notch filters at those points remove it while leaving most of the voice intact. Compression, reverb, and pitch shifting alter dynamics or character rather than targeting a specific frequency.

Question 37Media Production

A camera operator wants a smooth horizontal move across a room without visible footsteps. Which tool is designed for this?

  1. A dolly on track Correct answer.
  2. A handheld stabilizer
  3. A shoulder mount
  4. A jib arm

Explanation

A dolly running on track produces a level, repeatable lateral move at controlled speed, which is why it is standard for smooth tracking shots. Handheld and shoulder-mounted rigs transmit operator motion, and a jib is built for vertical arcs rather than level travel.

Question 38Media Production

Which aspect ratio is wider than 16:9?

  1. 1.66:1
  2. 1.85:1 Correct answer.
  3. 4:3
  4. 1.33:1

Explanation

16:9 is approximately 1.78:1, so any ratio with a larger first number is wider. The 1.85:1 ratio is a common flat widescreen format and exceeds 1.78:1. The other listed ratios are all narrower than 16:9.

Question 39Media Production

During a dialogue scene, an actor's lavalier rubs against clothing each time she turns her head. What is the most effective fix?

  1. Reposition the microphone and add a fabric mount Correct answer.
  2. Apply heavy compression in post
  3. Raise the input gain on the recorder
  4. Point a shotgun at the actor from off camera

Explanation

Clothing rustle is a mechanical problem, so the remedy is physical: move the lav off the rubbing fabric and use a mount that isolates it. Gain changes amplify the noise, and processing cannot cleanly separate rustle from speech. A boom may help but does not solve the lav itself.

Question 40Media Production

A scene alternates between a wide establishing shot and tight close-ups of the same conversation. Which editing approach best maintains the audience's sense of geography?

  1. Keeping all camera positions on one side of the action line Correct answer.
  2. Cutting to a new angle every two frames
  3. Inserting unrelated B-roll between each line
  4. Crossing the axis between the wide and the close-ups

Explanation

Staying on one side of the action line keeps screen direction consistent, so the wide and the close-ups read as part of the same space. Crossing the line flips left and right and disorients the viewer. Rapid cutting or unrelated inserts would further break spatial logic.

Question 41Media Production

A colorist wants to warm a cool-looking exterior without shifting the neutral gray walls. Which tool is most targeted?

  1. A lift-gamma-gain adjustment on all channels
  2. A secondary qualifier limited to skin and sky tones Correct answer.
  3. A global saturation boost
  4. A full-frame brightness increase

Explanation

A secondary qualifier isolates a chosen range of hues or luminance so corrections apply only there, leaving neutral surfaces untouched. Global saturation and brightness changes affect every pixel, and lift-gamma-gain adjustments across all channels shift the whole image.

Question 42Media Production

What is the main function of a script supervisor on set?

  1. To manage the production budget and purchase orders
  2. To maintain continuity and log takes against the script Correct answer.
  3. To design the lighting plan with the director
  4. To operate the boom microphone during dialogue

Explanation

The script supervisor tracks what was shot, notes deviations from the script, and guards continuity of props, wardrobe, and action between takes. This record guides the editor and prevents errors across coverage. Budget, sound, and lighting fall to other departments.

Question 43Media Production

A documentary subject will be filmed walking through a crowded market. Which audio plan gives the most usable dialogue?

  1. Fit a wireless lavalier with a wind-protected element Correct answer.
  2. Record dialogue later and discard all location sound
  3. Rely on the camera's built-in microphone
  4. Place a single condenser microphone at the market entrance

Explanation

A body-worn wireless lav keeps the voice close and consistent regardless of crowd noise or movement. Built-in camera mics pick up everything around the lens, and a fixed microphone cannot follow a moving subject. Discarding location audio loses natural reactions and sync.

Question 44Media Production

An editor must shorten a 30-minute cut by four minutes without losing any story beats. Which approach is most sound?

  1. Trim handles and pauses within and between existing shots Correct answer.
  2. Delete every alternate angle from the sequence
  3. Speed up the entire timeline by a fixed percentage
  4. Remove entire scenes that contain key plot information

Explanation

Trimming within shots and tightening pauses removes slack while preserving narrative content. Cutting whole scenes or globally speeding up the timeline damages story or distorts motion and audio pitch. Removing alternate angles alone rarely yields enough runtime.

Question 45Media Production

Why is a lower ISO generally preferred when lighting permits on a digital cinema camera?

  1. It increases the maximum frame rate available
  2. It reduces visible noise and preserves dynamic range Correct answer.
  3. It shortens the recording time per clip
  4. It widens the lens's angle of view

Explanation

At lower ISO settings the sensor's native sensitivity yields cleaner shadows and more usable highlight and shadow detail. Pushing ISO amplifies signal and noise together, narrowing latitude. Frame rate, field of view, and clip length are unaffected by ISO.

Question 46Media Production

A production wants to shoot a night exterior with practical streetlights and keep a shallow depth of field. Which combination best achieves this?

  1. A fast lens, a wide aperture, and a high-base-ISO camera mode Correct answer.
  2. A slow lens stopped to f/11 and a low ISO
  3. A fast lens at f/16 with added neutral density
  4. A slow lens wide open with a heavy gain boost

Explanation

A fast lens used wide open admits more light and narrows depth of field, while a camera mode with a high base ISO improves sensitivity in low light. Stopping down or adding neutral density reduces light, and heavy gain on a slow lens introduces noise without controlling focus depth.

Question 47Media Production

A 25 fps project must be delivered for a 30 fps broadcast slot. Which conversion approach best preserves both motion and audio pitch?

  1. Simply changing the timeline frame rate and exporting
  2. Duplicating every fifth frame and stretching the audio
  3. Slowing the entire program to 24 fps and re-recording dialogue
  4. Using a standards conversion with motion interpolation and pitch-corrected audio Correct answer.

Explanation

Converting between 25 and 30 fps requires new frames to be generated, which standards converters do through motion interpolation, while audio must be time-corrected to keep pitch natural. Naive frame duplication causes judder, and simple rate changes desynchronize sound. Re-recording dialogue is unnecessary for a format conversion.

Question 48Media Production

A producer must guarantee that a finished master can be re-graded and re-cut years later by another studio. Which deliverable set is most appropriate?

  1. A camera-original archive plus an uncompressed or lightly compressed master and an edit decision list Correct answer.
  2. A compressed proxy reel with burned-in timecode
  3. A single high-bitrate H.264 MP4 of the final cut
  4. A DVD ISO of the final program

Explanation

Long-term reuse requires the highest-quality source material, a master with minimal compression, and documentation such as an edit decision list so the cut can be reconstructed. Delivery codecs like H.264 or DVD discard the latitude and structure needed for future work, and proxies are review tools only.

Question 49Media Production

A director wants a single continuous take that follows a character from a street into a building. Which planning consideration matters most?

  1. Maximizing the number of camera angles captured
  2. Rehearsing the path, lighting transitions, and hidden crew resets Correct answer.
  3. Choosing the widest lens available regardless of space
  4. Recording dialogue entirely in post-production

Explanation

A long unbroken take depends on precise choreography of camera, cast, and crew, plus lighting that works across the whole path and concealed points for resets. More angles contradict the single-take intent, and post-only dialogue sacrifices sync and performance. Lens choice must serve the space, not simply be widest.

Question 50Media Production

An editor notices that dialogue recorded on two different days has noticeably different background noise. Which fix best preserves the performances while unifying the sound?

  1. Raising the music level to cover the difference
  2. Applying the same heavy noise reduction to every clip
  3. Replacing all location dialogue with synthesized speech
  4. Using ambience matching and gentle noise reduction per clip Correct answer.

Explanation

Each clip needs individual treatment: reduce noise only as far as necessary, then blend the backgrounds with matching ambience so transitions feel seamless. Uniform heavy processing damages the cleaner takes, and masking with music alters the intended mix. Replacing performances is a last resort, not a routine fix.
