Subtitles and Caption Subtitle Timing and Synchronization 1 — Questions and Answers
Question 1: What is the standard minimum duration a subtitle should be displayed on screen?
- 0.5 seconds
- 1 second (Correct answer)
- 3 seconds
- 5 seconds
Correct answer: 1 second
Subtitles should be displayed for a minimum of 1 second to allow viewers enough time to read even a short caption.
Question 2: What is the recommended maximum display duration for a subtitle with 2 full lines of text?
- 1 second
- 3 seconds
- 7 seconds (Correct answer)
- 10 seconds
Correct answer: 7 seconds
A 2-line subtitle should generally not exceed 7 seconds on screen to avoid viewer fatigue and maintain pacing.
Question 3: What does 'timecode' refer to in subtitle synchronization?
- The runtime of the entire video
- The in and out points that determine when a subtitle appears and disappears (Correct answer)
- The frame rate of the video file
- The export time for the subtitle file
Correct answer: The in and out points that determine when a subtitle appears and disappears
Timecode in subtitle files specifies the exact in-point (when a subtitle appears) and out-point (when it disappears) for each caption entry.
Question 4: What is 'subtitle latency' in live captioning?
- The file size of subtitle data
- The delay between speech being spoken and the caption appearing on screen (Correct answer)
- The gap between two subtitle entries
- The time it takes to export a subtitle file
Correct answer: The delay between speech being spoken and the caption appearing on screen
Subtitle latency refers to the unavoidable delay between a live speaker's words and when the corresponding captions appear on screen.
Question 5: What is a 'subtitle gap' and why is it important?
- A missing word in a subtitle
- The brief blank time between two consecutive subtitle entries (Correct answer)
- The black bars around a video
- The encoding pause in subtitle files
Correct answer: The brief blank time between two consecutive subtitle entries
A subtitle gap is a short blank interval (typically 2-4 frames) between consecutive subtitles that prevents two entries from appearing to merge together.
Question 6: What reading speed (in words per minute) is typically used as a benchmark for subtitle timing in the US?
- 100 WPM
- 150 WPM
- 180-200 WPM (Correct answer)
- 300 WPM
Correct answer: 180-200 WPM
US subtitle standards typically target 180-200 words per minute as a benchmark for average adult reading speed when setting caption durations.
