Text, Punctuation, and Grammar
The following guidelines are in place for text, punctuation, and grammar:
- Use mixed-case text, except in the case of screaming or shouting which should be in ALL CAPS.
- Use a white font color on a black background. Note: this is the default setting in Camtasia and Vimeo.
- Use two lines maximum per caption.
- Always use an Oxford comma when captioning a list.
- Type numbers as numerical figures (1,000 instead of one thousand).
- If there is a hesitation, stutter, or pause, caption the hesitation.
- If there is a significant pause, use ellipses.
- Use quotation marks for onscreen readings (e.g., quoting an article, another person, etc.).
Sound Effects and Music
The following guidelines are in place for sound effects and music:
- When a sound effect is used, enclose the description of the sound effect in square brackets: [applause]
- Off-screen sound effects should be enclosed in square brackets and be italicized: [crash]
- Use punctuation to indicate speed and/or pace of sound: [dog barking] woof…woof…woof
- Background music does not need to be accounted for in closed captioning.
