Basics of Captioning
When you are captioning you will want to do the following:
- Should be the exact words that are spoken excluding ums and stuttering (unscripted content)
- Should be the exact words that are spoken including ums and stuttering (scripted content)
- Important background sounds should be conveyed in the captions in brackets or parentheses
- Use italics to convey speech that is spoken off screen
- Use proper punctuation to convey meaning and to emphasize certain speech when needed.
- Do not reveal information that was intentionally excluded from the language
- Music: should include the title and the artist
- Exception when the music is setting a mood
- Example: [SPOOKY MUSIC]
- Exception when the music is setting a mood
- Music: If the lyrics are important you must include them in the captions
- If you cannot make out what is being said notify the user of such using plain language
- Example: (Inaudible whispers)
- If there is cursing you need to remove it from the captions and replace it with a designated word such as BLEEP
- Notify the user when words are whispered or mouthed
- Example:
- Whispered:
- (Whispered):
- Example:
- Describe sounds that are in the audio in terms of the sounds themselves not what is causing the sound
- When someone is speaking you must identify them at the beginning of them speaking
- Example: [BROOKE] or [Brooke]
Auto Captioning
If you have a YouTube or Vimeo account, you can have these platforms auto caption the video for you and then you can go through and review the captions and make any changes that you need. We recommend using YouTube for this as it allows you to have more control over the timing of the captions after auto captioning has occurred. Once Captions are complete you can download the video with Captions or link directly to your newly captioned video.
User Impact
Auto captioning can help to speed up the captioning process to provide access to the video more quickly than manually creating the captions, but a manual review will need to be completed so that the captions are accurate and complete.
