Edit captions in YuJa

Captions and a transcript are automatically generated for each video uploaded to (or recorded in) YuJa. These may not always be accurate or clear and so both items can be edited through the YuJa Media Library (i.e. not from within Brightspace). Human-made captions can also be uploaded to replace what was generated.

Captions can be made for existing YuJa videos, including those transferred from Echo360.

Other video formats in Brightspace can be captioned, although doing so is more complicated.

Upon making edits to a video, captions may no longer line up with the audio. Selecting Save will present the option to have them automatically re-aligned.



Access the YuJa Media Library

Caption and transcript changes must be done in the Media Library, which offers accessibility management options as well as a video editor where changes can be made alongside video playback.

Brock users can get to their Media Library directly through http://brocku.video.yuja.com. This provides access to all content associated with the host account, including that which has been uploaded and embedded in Brightspace and anything transferred from Echo360.

The Media Library can also be found within Brightspace and is listed in the Course Tools sub-menu on a course site’s navbar.

Find the video to be edited

The main page of the Media Library is My Media (or Manage Media), which will display all existing videos associated with the user’s account. Videos will be listed chronologically with the most recently added first, but this can be changed using Sort in the top-right. There is also a Search box in the top-left.

A video’s thumbnail will display a list of options when hovering over it. This list will not be complete if the upload has not yet been fully processed, which may take some time.

Find the video to be edited and select Edit. A fullscreen video editor will open.

Edit captions and apply to transcript

The video editor provides caption editing tools that can be used to increase the accuracy of the automatically generated text or to correct captioning when media content is trimmed or altered. This includes the ability to add, change, or delete captions, and to alter the timestamp associated with a caption.

How to use the caption editor

The Caption (CC) options are near the top-left of the editor screen and provide offers several tools for making adjustments.

[1] Adjust the start and end times for each closed-caption line. This will shift the text to match a different start/end time in the video. Edits to the video timeline itself will update here and changes are identified through a color-coding system.

[2] Double-click to edit the caption text to add notes, correct wording, update pronouns, etc.

[3] Add or delete caption line. Add a new piece of descriptive text, missing line, or remove any unwanted lines by clicking on the trash bin icon..

[4] Navigate through the timestamps and captions.

[5] Find and replace options (the magnifying glass icon in the upper-right corner) can be used to quickly replace multiple instances of a miscaptioned word.

[6] Switch languages to edit the caption track in another language. This can only be done if the captions exist in another language, which must be requested in the Media Details page.

Once done, click the Save button at the top of the entire editing page. This will prompt some options about saving along with confirmation that the caption changes will be merged with transcript text.

The option to apply the caption edits to the transcript is turned on by default, so any changes to the captions will also affect the transcript.

Enable missing captions, access transcripts, or upload external captions

Missing captions

There are several reasons that captions may not have been generated (for both new and old videos). In some cases, this can be fixed simply by going to the accessibility options and requesting captions. Externally generated captions can be uploaded and applied to override existing captions or to provide a superior, human-generated option.

Hover over the video in question and click More…

Scroll down the Media Details options and find Accessibility [1].

Click Auto Caption [2] and then Send Caption Request (both of which are misnomers in this case) to force the autogeneration of captions. Click Save Accessibility and Close. Return to the video and play, you should see that captions are being processed.

External captions

The Accessibility page in a video’s Media Details screen will also facilitate uploading externally created caption files.

Hover over the video in question and click More…

Scroll down the Media Details options and find Accessibility [1].

Choose Upload and select Caption. Choose the appropriate language from the dropdown box and upload. Click Yes to overwrite any old captions and to complete the upload process.

If SRT, XML, and WebVTT caption files are formatted to include, bold, italic, or underlined words or phrases, the Media Player will display the caption accordingly.

Video clipping and captions

While editing a media file, especially trimming, can cause the closed-caption timestamps to become invalid. In these cases, the Video Editor will notify users which part of the closed captions would be affected so users can act accordingly.

 

  1. Hover over a media file and click Edit to open up the Video Editor.

  2. Trim or clip a part of the media file.

  3. The Video Editor will show three different statuses to let users know which closed-caption lines are affected.

  • Blue - Valid: These closed-caption lines are not affected by the trim.

  • Red - Pending Removal: These closed-caption lines will be removed by the trim.

  • Yellow - Invalid Timestamp: These closed-caption lines are out-of-sync because of the trim.
