Video Editing Audio Editing and Mixing 1 — Questions and Answers
Question 1: What does 'diegetic sound' mean in film and video?
- Sound added in post-production
- Sound that originates from within the story world and is heard by characters (Correct answer)
- Background music the audience hears
- Sound effects layered in mixing
Correct answer: Sound that originates from within the story world and is heard by characters
Diegetic sound comes from sources within the narrative world—such as dialogue or ambient noise—and can be heard by the characters.
Question 2: What is a 'J-cut' in video editing?
- A jump cut with audio removed
- When the audio from the next clip starts before the video cut (Correct answer)
- When video transitions before audio
- A cut used only in interviews
Correct answer: When the audio from the next clip starts before the video cut
A J-cut is when the audio of the next scene begins before the video cut, creating a smooth audio transition into the next scene.
Question 3: What unit is used to measure audio loudness in video post-production?
- Hz
- dB SPL
- LUFS (Correct answer)
- RPM
Correct answer: LUFS
LUFS (Loudness Units relative to Full Scale) is the standard unit for measuring integrated audio loudness in broadcast and streaming.
Question 4: What is the recommended integrated loudness target for most streaming platforms according to broadcast standards?
- -6 LUFS
- -14 LUFS (Correct answer)
- -23 LUFS
- -32 LUFS
Correct answer: -14 LUFS
Most streaming platforms like Spotify and YouTube normalize audio to approximately -14 LUFS integrated loudness.
Question 5: What does a 'compressor' do to an audio signal?
- Boosts all frequencies equally
- Reduces the dynamic range by attenuating loud signals above a threshold (Correct answer)
- Removes background noise
- Adds reverb to the signal
Correct answer: Reduces the dynamic range by attenuating loud signals above a threshold
A compressor reduces the volume of audio signals that exceed a set threshold, narrowing the dynamic range for more consistent levels.
Question 6: What is the purpose of a 'room tone' recording on a film set?
- To test microphone sensitivity
- To capture the ambient silence of a location for filling gaps in dialogue editing (Correct answer)
- To record background music
- To calibrate speaker levels
Correct answer: To capture the ambient silence of a location for filling gaps in dialogue editing
Room tone is a recording of the natural ambience of a location used to fill in pauses or gaps during dialogue editing without dead silence.
