A Captioner’s Quick Guide

  • ONLY one sentence per caption cell. DO NOT end one sentence and begin another in the same caption!
  • Do not write [cannot understand.] Use [unintelligible].
  • Include EVERY um, ah, er, etc.
  • Put a comma BEFORE AND AFTER every um, ah, eh, etc.
  • Spell out “et cetera” when used by the speaker.
  • Write out the word “okay,” NOT “OK.”
  • Spell out numbers 1-10 unless they are in a list.
  • When writing numbers bigger than 10, then make all numbers numerals, E.G., “9, 10, 11,” not “nine, ten, 11.”
  • Check whether your video player will use italics — many do not.
  • Identifying a speaker gets its own line, when possible.
  • Speaker identification is in parentheses (Jenna).
  • Denote stuttering with hyphens and no space: T-t-t-today.
  • Sound effects go in square brackets [woosh], and should be noted only if the sound effect is integral to the content.
  • Use onomatopoeia for sounds: “[machine gun firing] rat-a-tat-tat”.
  • Write [applause] for an audience not [clapping], but if a single person is clapping, use [clapping].
  • Use ellipses for long pauses… within a sentence.
  • Double check spelling, even that of the autogenerated captions, as well as if someone else has done a first check of a file.
  • Add a blank caption if there is a long pause between sentences.
  • If a quote runs longer than one caption cell, “use open quotation marks for each continuous frame, then close the final frame.”
  • Captions cannot be more than two lines each unless told otherwise.
  • Left-justify captions.
  • Make sure there is a blank caption at the beginning and end of each video. This is dependent on the captioning program.
  • Double check your own work!
