How do I create a caption file for video or audio content?

A caption file can be uploaded to Panopto or VoiceThread to accompany audio and video files for closed captioning. Captions make your content accessible to students who cannot hear or who are hard of hearing. To begin, open your audio or video file in a media player that allows you to see the time stamp in hours, minutes, seconds, and milliseconds. Then, open a plain text editor. You can use Notepad if you are on a PC or TextEdit if you are on a Mac.

Parts of a Caption File

Use the guidelines above to create your caption file in a plain text editor.

  1. Sequence number: The number order of how the captions will appear on the screen.
  2. Time-codes: The start and end time that the caption will appear on screen in hours, minutes, seconds, and milliseconds. The format is: hours:minutes:seconds,milliseconds.
  3. Arrow: A two-hash arrow should separate the start and end time-codes.
  4. Caption text: The audio during this time frame in text form.
  5. Blank line: There should be one blank line between each caption sequence.
