Video Closed Captioning and Subtitles

NetX supports closed captioning (subtitles) for video previews through the use of .vtt files. Producers and above can manage closed caption files for video assets.

The only supported closed captioning file type in NetX is .vtt. Any other captioning formats must be converted to .vtt before they can be used for video captions. Other file formats can be attached to a video asset as a view, but will not be displayed during video previews.

Adding closed captioning

Your VTT  view must be named previewVTT  or it will not be recognized by the video player. There can be only one previewVTT attached to a video asset at a time. 

  1. Navigate to an asset's detail page
  2. Select the Views tab. 
  3. Use the plus button along the top-left of the tab's header; this will initiate the Add view action. 
  4. Give your new view the name previewVTT, a Description (optional), and select a file using the window's file picker or by dragging a file from your local storage.
  5. To upload your view, click Save; to close the window without uploading the view or saving any configuration changes, click Cancel.

For more information regarding asset views and their management, see Asset Views .

Using closed captioning

Turn closed captioning on and off for a video by hovering over the cc button that appears with the video's playback controls. Toggle between captions and captions off to watch the video with and without subtitles.
