Adding / Editing Captions on Media Library Content

Updated on

The Media Library (Panopto) has the ability to manually upload captions or add captions through automatic speech recognition (ASR). This guide will show how to import and edit ASR captions as well as upload captions created elsewhere.

Captions created through ASR are not 100% accurate. Captions added to media this way should be reviewed and edited before being used for your content.

Importing Automatic Speech Recognition (ASR) Generated Captions

  1. In the Media Library folder with content that you you want to add captions to, click the "Edit" button that appears when you hover over the media item.
  1. In the video editor, select "Captions" from the left-hand menu.
  2. From the "Import captions" drop down menu select the "Import automatic captions" option. 

Newly created media may not have the option to "Import automatic captions" available immediately as the media is still being processed. This process can take a few minutes, depending on the length of the media. Check back in the video editor after the media has had more time to process.

If you do not see the option to import automatic captions after a prolonged period (20+ minutes), please contact [email protected] and provide a link to your video for reprocessing.

  1. The captions will populate with the text and timestamps listed.

It is highly recommended to edit your ASR generated captions, as they can contain numerous errors.

  1. When done adding your captions, click the "Apply" button in the media editor along the top.

Editing Your Captions

  1. In the Media Library folder with content that you you want to add captions to, click the "Edit" button that appears when you hover over the media item.
  1. In the video editor, select "Captions" from the left-hand menu.
  2. Click the Three Dot icon next to the timestamp and select the "Edit" Pencil icon to open a specific caption block to edit.
  1. In the pop-up window that opens edit the "Caption" in the text box. You can also adjust the timestamp of when this caption plays by changing the "Time."
  2. When done, click the "Save" button.

The "Time" field is represented as hours:minutes:seconds:milliseconds (h:mm:ss:ms).

Example: If you wanted to adjust a caption's timestamp from displaying 53 seconds into the media to 57 seconds into the media, the timestamp would look like this:

0:00:53:00 → 0:00:57:00

  1. When done editing your captions, click the "Apply" button in the media editor along the top.

Uploading a Caption File

If you have had captions created from another service, you can upload them to your media content.

Panopto currently supports *.srt, *.ashx, and *.dxfp file types for captions.

  1. In the Media Library folder with content that you you want to add captions to, click the "Edit" button that appears when you hover over the media item.
  1. In the video editor, select "Captions" from the left-hand menu.
  2. From the "Import captions" drop down menu select the "Upload or request captions" option. 
  1. From the pop-up window that opens, select the "Choose File" button under the "Upload Captions" header.
    1. You can search your computer for the caption file you are looking to use.
  2. After the file has been selected, click the "Upload Captions" button.
    1. Once the captions have been uploaded, you can now edit the captions, if needed, by following the Editing Your Captions steps above.
  1. Once done adding and editing your captions, click the "Apply" button in the media editor along the top.
