Who can do this?
Administrators for all media; Instructors, and Teaching Assistants for media they own and for course media if editing is enabled for co-instructors/teaching assistants.

Some institutions generate their own closed captioning files rather than using a captioning service. Echo360 allows users to manually upload those captioning files to videos. You are also able to delete captions from a video if necessary.

It is also possible (if ASR is enabled) to download the transcript files for a Capture and upload them as captioning files. Alternately, users can select Apply to CC in the transcript editor to apply a transcript as a closed captioning file.

For tips and instructions on how to generate your own closed caption files, see the following online articles:

Adding captions to media

Users with editing rights on media can upload a captions file to be applied to an audio, video, or interactive media file. The instructions below assume the media is being selected from the user's library, however instructors and teaching assistant can also open the media details page from the class list by selecting Details from the video icon menu.

Caption uploads will either apply OR replace the existing captions on the media. If the capture already has a captioning file associated with it, uploading a new file replaces the existing captions with the new file's contents.

Only VTT and SRT file types are accepted as valid caption uploads.

To add closed captioning files to a capture

1. Click on the tile of a piece of media in your Library to open the media details page.
2. In the bottom section, click the Details tab as identified in the below figure.
3. Find the Captions entry identified in the figure below.
   
4. Click the chevron to the right of either Yes or Add (depending on whether the capture already has captions or not) and select Upload from the drop-down list.
5. In the Filepicker window that appears, navigate to and select the closed captioning file to apply to this capture. Only VTT and SRT file types are accepted at this time.

Once the file is uploaded, it is applied to and synced with the capture/video. This processing should take a very brief period of time. You will need to refresh the content details page in order to see the captions applied to the video.

NOTE that if a user edits the video, the captioning file may need to be re-done and re-uploaded for application to the edited video.

Deleting captions from media

Instructors can remove the captions from media that has them. This may be necessary if there is a problem with the existing closed captioning file and you do not yet have a valid file to apply to the media.

Deleting captions from a video is permanent and cannot be undone. BEST PRACTICE: Click the captions VTT file link from the Processed Files list, and download the current captions file prior to deleting from the video. This provides you with a copy of them to edit and upload later if necessary.

IMPORTANT: If the Delay video availability option is enabled (either at the section level specifically or as forced down from a higher level), removing captions from the video will make that media unavailable to students until captions are re-applied. As the instructor, you will see the video in your class list but students cannot see it and therefore cannot view it until it is captioned again.
