A semi-transparent black box or drop shadow behind caption text ensures readability regardless of the background scene brightness.

Question 2: When captions use a pop-on display style, how do they appear on screen?

They fade in and out gradually
They paint on word by word across the screen
They appear all at once as a complete block of text (Correct answer)
They scroll line by line from the bottom

Correct answer: They appear all at once as a complete block of text

Pop-on captions appear as a complete pre-prepared block of text all at once, then disappear, making them the preferred style for pre-recorded content.

Question 3: What is 'spotting' in the context of subtitle production?

Checking for spelling errors in captions
The process of marking the in and out timecodes for each subtitle entry (Correct answer)
Identifying which language a subtitle file uses
Converting subtitles to a broadcast format

Correct answer: The process of marking the in and out timecodes for each subtitle entry

Spotting (also called 'cueing') is the process of watching the video and marking the precise start and end timecodes for each caption or subtitle entry.

Question 4: What is 'subtitle segmentation' and what is its primary goal?

Breaking subtitle text at natural linguistic boundaries (after a clause or phrase) to aid reading comprehension (Correct answer)
Splitting a subtitle file into multiple smaller files for distribution
Dividing a video into segments each with their own subtitle track
Separating on-screen text captions from spoken-dialogue subtitles

Correct answer: Breaking subtitle text at natural linguistic boundaries (after a clause or phrase) to aid reading comprehension

Good segmentation splits subtitle lines at grammatically natural points so each line is a meaningful unit, reducing cognitive load on the reader.

Question 5: What is a 'roll-up' caption style?

Captions that spin onto the screen
Captions that roll in from the side
Captions that continuously scroll upward one line at a time (Correct answer)
Captions that appear in a bubble

Correct answer: Captions that continuously scroll upward one line at a time

Roll-up captions scroll upward continuously, typically showing 1-3 lines at a time, and are commonly used for live television.

Question 6: In subtitle localization, what does 'lip sync' or 'dubbing sync' refer to?

Matching the subtitle reading speed to the narrator's pace
Synchronizing two subtitle tracks in different languages
Matching subtitle timing and word choice to the mouth movements in dubbed audio replacements (Correct answer)
Ensuring audio and video are synchronized before subtitling
