Why are captions important?

Captions assist learners viewing bulbs and can add to the retention rate of information that has been presented. In addition, if a viewer is on a mobile device, captions can help accommodate their experiences if they can't play audio out loud. This is a mandatory requirement of many bulbs that require Americans with Disabilities Act compliance as well.

Upload/Fetching captions in the Designer

Private video host

The PlayPosit 3.0 designer supports uploading .vtt and .srt caption files, as well as fetching caption files that are already attached to video streams from other media hosts like YouTube, Kaltura, and MediaSite.

YouTube captions
  1. Switch to the Video Segments tab.
  2. Click the triple dots icon for the video you want to caption and select Edit Video Segment.
  3. Click Customize.
  4. From here, you can either drag and drop caption files directly over the dialog menu or click View Available YouTube Captions to retrieve existing caption files for that stream.
  5. Note:
    • If you are part of an institutional license, all captions except the auto-generated captions will be auto-fetched to the Bulb.
    • To enable live transcripts for YouTube videos, you must view captions to import caption files.
    • There are key differences between Free, Pro, and Institutional users when fetching captions.
      • Pro users must press the view button to receive captions on all YouTube videos.
      • Institutional users will have captions automatically fetched when adding YouTube videos.
      • Free users will not have the option to fetch auto-generated captions from YouTube videos.

    5. After clicking the View Available YouTube Captions button, click the check mark next to the captions file needing to be uploaded to the video segment.

    6. Lastly, click Download to add the caption file to the video segment. 

    To learn more about how to set your captions to autoplay in your bulb first open the instructor profile and then, click here

    Note: If multiple captions are fetched to the video segments, learners will see the first caption on the list by default, and they can select other captions in the setting. Instructors can rearrange the order of the captions in the list by dragging the icon in front of them. Also, for captions fetched from YouTube, if there is an English caption (not auto-generated) in the list, PlayPosit will display it as default regardless of its order.

    Note: We recommend checking all .srt and .vtt files with an srt checker before uploading. This is to ensure that any formatting errors can be identified and corrected, so that do not affect playback. If there are errors in the captions file try running this recommended online checker to fix the file

How to request captions in the designer

If you are part of an institutional license that has purchased a third-party caption integration add-on, you can request for certain videos to be captioned. Captions requested from a third-party caption integration will be professionally transcribed and 99% accurate.

  1. Click the Add Video button in the Video Segments stepper.
  2. There are two options to upload videos for requesting captions.
    Option 1:  Upload Video button (if you belong to an institution that has video hosting)
    Option 2: Paste an URL to the video into the  Input URL field. 
  3. After making your selection and the video has finished uploading click the Customize button.
  4. Click the Caption Orders button.
  5. Click Submit Order.
  6. You will now see a processing message.
  7. Processing can take some time depending on the length of your video clip. After your captions finish processing, usually within 24 hours, refresh the designer. You will see the captions appear for your video clip. Enable them by clicking on the settings gear located on the bottom right corner of the Designer, and selecting the specific caption file.

How to edit captions
