  7. When you first upload a video, choose the video language from the dropdown menu.
  8. Then, select the Add subtitles or CC button, and choose your specified language (e.g. English).

Uploading Caption or Transcript Files to YouTube Videos

If a transcript or caption file already exists for a video, simply upload the file to YouTube. This method is recommended.

Caption Files vs. Transcript Files

  • Caption files contain both text and time codes.
  • Transcript files only contain text and are saved as a plain text file (.txt). However, if the video is in English, YouTube can automatically synchronize your transcript with the video to create a caption file.

Uploading Caption or Transcript Files

  1. If you have a caption file, choose Upload a file. Select the Subtitles File Type and click Choose File. Select the Upload button. Preview the captions in the editor and make any necessary edits, then select Publish.
  2. screenshot of 'Upload a file' option highlighted.
  3. If you have a transcript file, choose Transcribe and set timings.
  4. screenshot of 'Transcribe and sync' option highlighted.
  5. This allows you to automatically align the timings of your transcript to your video within YouTube. Select the Actions dropdown menu and choose Upload a File. Select the Transcript File Type and click Choose File. Select the Upload button. Click Set timings to sync your transcript with the video. This will take a few minutes.
  6. screenshot of 'set timings' button.
  7. Once the captioning file is available, review the timing to ensure accuracy and select Publish.

Automatically Creating Caption Files from YouTube Videos

YouTube has provided a way to create caption files from videos you have uploaded. However, the quality of the captions is usually poor and you will probably need to edit the caption file manually.


  • Automatic captioning works best when the audio is clear and easy to understand. (E.g., background music or speaking in an accent can affect accuracy.)
  • The automatic captioning option may not be available for all videos.

Creating Caption Files

  1. In the Subtitles and CC tab select the automatic captions option (e.g., English (Automatic) ), if available.
  2. screenshot of the automatic captions option.
  3. Test the captions for accuracy by playing the video and reviewing the text concurrently. To edit the captioning file, select the Edit button and choose Overwrite. Then select the line that needs repair in the captioning editor text box.
  4. Use the Add below and Remove icons to add and remove captions as needed.
  5. screenshot of the captioning editor text box in use.
  6. After completing the captioning edits, select Publish to create a new caption file.

Finding Captioned Media

Just because the CC icon appears on a video doesn't mean it's been correctly captioned; this icon also appears when the video has been automatically captioned.

  1. To search for captioned videos only, type your search terms into the YouTube search bar and hit Enter. Select the Filter tab and under Features, choose CC (closed caption). Now all YouTube videos displayed should have captioning provided.
  2. screenshot of youtube search bar with CC filter tab highlighted.
  3. Another option is to type your search terms into the YouTube search bar followed by a comma and then CC (e.g. “web accessibility, CC”).

Removing Inaccurate Captions

To remove the Automatic caption track, under the Subtitles and CC tab, select the original automatic captioned file and under the Actions tab, choose Unpublish. This ensures viewers will not be able to see the inaccurate version on YouTube.
