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.

Note: If you are part of an institutional license, all captions will be auto-fetched, eliminating the need to click view. 

To enable live transcripts for YouTube videos, you must view captions to import caption files.

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: There are key differences between Free, Pro, and Institutional users when fetching captions.
    1. Pro users must press the view button to receive captions on all YouTube videos.
    2. Institutional users will have captions automatically fetched when adding YouTube videos.
    3. 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.

    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 https://subtitletools.com/srt-cleaner.

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. Currently, ordering captions is only supported for MP4 video sources, which can be added in two different ways. Option 1: Upload MP4 button (if you belong to an institution which has MP4 video hosting), Option 2: Paste an MP4 URL 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

Launch the Designer and make sure that captions are already present on the bulb.

  1. In the Video Segments tab, select the CC (closed captions) button on a video with a caption file.  
  2. Click the captions file dropdown menu that needs to be edited.
  3. Select the pencil icon.
  4. The captions editor will open in a new tab. Click on the text box of the caption line that needs to be edited.
  5. Enter in new text for the caption at the given timestamp. To find the exact timing for a caption in a bulb, switch back to the PlayPosit Designer tab and reference the timestamp in the bottom left of the screen when a caption appears. 
    Note:  Timestamps are not editable and cannot be changed. 

    Edit the caption as needed at that time stamp on the captions editor page.

    Note:  Caption lines must have text, they cannot be left blank. 

  6. When editing is complete click the Save Captions button. 
  7. Captions will be saved when a toast saying Captions successfully updated appears.
  8. Close the tab and return to the designer. The newly edited captions file will be automatically added to the video segment.
Note:  If a section of a video is cropped out the caption at that time stamp will also be trimmed out of the player.
