A Captioner’s Quick Guide

  • ONLY 1 sentence per caption cel. DO NOT end one sentence and begin another in the same caption!!!
  • Do not write “Cannot Understand.” Use “Unintelligible”.
  • Include EVERY, um, ah, er, et cetera.
  • 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.
  • 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 it.
  • 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 space between sentences.
  • If a quote is longer than one frame, “use open quotation marks for each continuous frame, then close the final frame.”
  • Captions cannot be more than 2 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!
