Closed captions provide text descriptions of the audio for audience members who cannot hear the audio (or hear it well). You will use Caption Editor to add new captions and update existing ones. Typically, you will use Captioning Editor to update captions created using speech-to-text services like IBM Watson or 3Play Media-ASR (Automated Speech Recognition). Caption Editor allows you to update a caption’s content and the time it appears in the presentation. You can also remove captions.
When you download a presentation’s captions (DFXP
file), publish a
presentation to go, or export it, the changes
made with Caption Editor are included. We strongly recommend downloading and
making a backup copy of your original captioning file (one created using a
captioning service or third-party tool) before making updates using Caption
Editor.
To add update your presentation’s captions:
1. On the presentation’s properties page, click Edit Captions. Caption Editor launches in a new page and the presentation begins playing.
2. Each caption in the presentation appears in the caption panel and the timeline. You can use either the panel or timeline to navigate to and select the caption you want to update.
3. By default, the video automatically starts playing and the timeline tracks the video positions. Clear the Track timeline while video plays and Autoplay video check boxes to disable these features. You can also use keyboard shortcuts to toggle these features on and off. Click Keyboard shortcuts for more information.
4. Click the Add tab to update your captions as needed:
