Panopto: Captions

Panopto offers several different ways to add captions to recordings, including translated captions. Once captions are added, viewers will be able to turn them on during playback in Panopto’s viewer window or, if they download a recording, using any other media player that supports captions.

Warning: Captions for recordings published on a college website or used in academic courses must comply with the Americans with Disabilities Act (ADA). While this articles covers how to create and edit Panopto's automatic captions, these captions are not always ADA-compliant! Please read the Captioning help doc to ensure your recordings' captions meet this mandate.

ASR Captioning in Panopto

By default, Panopto automatically adds English automatic speech recognition (ASR)-generated captions for uploaded recordings that do not already have captions. This means if you upload a captioned video, Panopto will NOT overwrite those captions.

Some important things to know about this process include the following:

  • The ASR process starts after a recording has finished uploading. Processing times are typically shorter than the duration of the recording, but may take up to 24 hours in periods of heavy demand. If it takes longer than that, please contact the Help Desk.
  • When Panopto imports a Zoom recording, the recording's caption file is also imported. So, if the recording has captions, ASR captions will not be generated for these videos. (Zoom recordings imported without captions will receive ASR captions).
  • ASR captions are saved as a separate file that is formatted for display during playback (closed captioning). They are NOT embedded in the video itself (open captioning).
  • ASR captioning is available in languages other than English. See Panopto's article How to use multiple language ASR captioning for supported languages and instructions on how to enable them.

Edit caption files outside Panopto

If captions need extensive editing or you want to translate them to create subtitles, it may be easier to export the caption file, edit it outside of Panopto, and then re-upload it to apply your changes.

Export caption files

  1. Log into Panopto and find your recording.
  2. Click  Settings.
  3. Click Captions.
  4. In the Available Captions menu, select the language of the caption file you wish to download.
  5. Click Download file.

Caution: The Download unedited caption file option includes sections of the video that have been cut or moved in the video editor. Make sure to delete them before you begin editing outside of Panopto.

Edit the downloaded file

  1. Open the downloaded captions in a text editor like NotePad (Windows) or TextEdit (macOS)
Warning: Do NOT use a word processor like Word or Google Docs for editing, as they will add invisible code to your file that will create issues when you upload it back to Panopto.
  1. Notice how the document is formatted and preserve this format as you edit. Each caption consists of three lines, with a blank line after each one:
    • Line 1: Caption number (does not appear on screen).
    • Line 2: Caption display period. For instance, 00:00:01,000 –> 00:00:03,500 means the caption appears one (1) second into the video timeline and disappears at 3.5 seconds.
    • Line 3: The caption text.
  2. When you are finished editing, save the file with an .srt file extension.

Import caption files

  1. Log into Panopto, and find the recording.
  2. Click Settings.
  3. In the pop-up menu that opens, go to the Captions tab.
  4. If you need to replace an existing caption file, click its language in the Available Captions menu. Then, click Delete Captions.
  5. In Upload Captions menu, choose the language of your caption file. Then, click Choose file and browse for the saved .srt file on your device. If your captions are based on the edited (e.g., trimmed) version of the recording, check Captions are based on the edited sessions
  6. Click Upload Captions

Note: You can upload multiple caption files in different languages to provide subtitle translation. See How to Add Translated Captions for details.
