Subtitles and Caption Caption Timing and Synchronization 2 — Questions and Answers
Question 1: What is 'caption drift' in the context of live broadcasts?
- Progressive accumulation of delay between audio and captions over time (Correct answer)
- Gradual movement of caption position on screen
- Changes in caption font size during a program
- Variation in caption reading speed requirements
Correct answer: Progressive accumulation of delay between audio and captions over time
Caption drift occurs in live broadcasts when small timing delays accumulate, causing captions to fall progressively further behind the audio.
Question 2: Which timecode format is most commonly used in professional subtitle files for film and broadcast in the U.S.?
- HH:MM:SS:FF (hours:minutes:seconds:frames) (Correct answer)
- MM:SS (minutes:seconds)
- UNIX timestamp
- Milliseconds only
Correct answer: HH:MM:SS:FF (hours:minutes:seconds:frames)
Professional subtitle and caption files use SMPTE timecode format (HH:MM:SS:FF) which includes frame-level precision.
Question 3: What is the recommended maximum gap between the end of one caption and the start of the next?
- No more than 2 seconds (Correct answer)
- No more than 5 seconds
- No more than 10 seconds
- No limit as long as no speech occurs
Correct answer: No more than 2 seconds
Best practices recommend gaps between captions not exceed 2 seconds to avoid confusing viewers about when speech resumes.
Question 4: In subtitle production, what does 'snapping' a caption to a scene cut mean?
- Aligning the caption in or out point to coincide exactly with a video edit (Correct answer)
- Removing captions during scene transitions
- Adding a visual transition effect to captions
- Splitting long captions at cut points
Correct answer: Aligning the caption in or out point to coincide exactly with a video edit
Snapping aligns caption timing precisely to video edit points to avoid captions crossing cuts, which looks unpolished.
Question 5: What is the '6-second rule' in captioning?
- The maximum recommended duration for a single caption block (Correct answer)
- The minimum time before captions must appear after dialogue starts
- The required gap between program segments
- The maximum allowed caption latency for live broadcasts
Correct answer: The maximum recommended duration for a single caption block
The 6-second rule states that no single caption block should remain on screen for more than 6 seconds to maintain viewer engagement.
Question 6: What technique is used to keep captions readable when speech is faster than the maximum recommended caption rate?
- Condensing or paraphrasing the spoken words (Correct answer)
- Increasing the caption font size
- Using abbreviations exclusively
- Splitting the caption across multiple screens
Correct answer: Condensing or paraphrasing the spoken words
When speech exceeds the maximum readable rate, captioners condense dialogue while preserving meaning to keep captions readable.
