File Formats for Closed Captioning Files

  • Vimeo prefers WebVTT file format
  • Youtube prefers SCC file format

Double check the closed captioning for accuracy

No one is perfect, that is why it is important to double check the closed captions for accuracy:

  • Does the captioning name the person speaking, and switch when a new person is talking?
  • Does the captioning describe any important sounds like a “door creaking”, momentary pauses for effect: “silence”, “foreboding music playing”, or a “loud crashing noise” that is important for viewer to know?
  • Are the captioned words and spellings of the words correct?

Get Permission for People’s names

Do not to use students names without permission. This is not an accessibility standard, but it is the right thing to do.

Changing Closed Captions from

Changing closed captions on

If they need to make any changes, they can change them on An Intro to Rev’s New Captions Editor.

Changing closed captions after downloading the file from

If you need to change them after downloading them from you can edit them in youtube, but for vimeo you would need to edit the file itself which would be better handled by editing it on and downloading it again.

  • Youtube Edit or Remove Captions -
    “Go to your Video Manager. Next to the video you want to edit captions for, click Edit > Subtitles and CC.” etc…
  • Vimeo Captions and subtitles -
    “You can edit existing captions or subtitles for your video by downloading the captions or subtitles file from the Advanced tab of your video settings, making the changes directly in the file, and then re-uploading the file to Vimeo.”

Linking your channel to your YouTube and/or Vimeo channel

If possible link your channel to your YouTube and/or Vimeo channel to your account, so you do not need to download the closed captioning files anymore. Please not you can link multiple channels / accounts.
