Subtitle (Closed Caption) Formatting
The Edit Subtitle (Closed Caption) dialog box enables you to add new or edit existing subtitles. It can be accessed by clicking on the Edit subtitles button on the Editing toolbar.
The following fields on the Subtitle / Closed Captioning user interface are described below:
 
Icon
Name
Description
Subtitle number
Displays the incremental number of the subtitle. As more subtitles are added, the number increases by one.
Play
Plays the clip so that you can view the video content while you type your subtitle.
Replay
Replays the clip.
Replay Slow
Replays the clip in slow motion.
Merge with Next Subtitle
Enables you to merge the current subtitle with the next subtitle.
Split at Cursor Position
Enables you to split the subtitle at a position within the subtitle where you place your cursor.
Begin / End
Displays the beginning and ending timecode of the subtitle.
Duration
Displays the duration of the subtitle.
Line / Characters
Displays the line of the subtitle, and the number of characters contained in it. The C/L ratio shows the number of characters per line that is a useful indication for subtitle display.
For some formats (e.g., WebVTT), above a definite value, the subtitles will be displayed on multiple lines.
The C/L ratio can indicate when another line is displayed, but it depends on the subtitles format.
*A specific subtitle format can be configured by your System Administrator in the SAAS platform, which then can be used to burn subtitles in the video.
Characters per Second
Displays the number of characters per second in the subtitle line.
*This value can help the editor that writes subtitles to input a sentence with a comfortable length. In fact, it has been demonstrated that a user can easily read under a value below 12, and can have some difficulties for values between 12 and 16. Above 16, the user will most likely not read the subtitle completely.
