Captions and subtitles often have pre-defined specifications, especially for broadcast use. This can include how long a subtitle lasts on screen for, or how many characters it has. In CaptionHub, we refer to this specification as Limits. CaptionHub helps you create technically accurate captions by continually checking that your captions obey these limits.
You're able to specify default limits in Team Settings. This means that every new set of captions you create will default to these limits. You're able to override these limits from the Edit limits option in the drop-down menu on the Edit page.
