REACH - Ordering Captions For Media Per Entry

This article describes how to order Kaltura REACH captions and view captions' requests through Kaltura MediaSpace (KMS) and through Kaltura Application Framework (KAF) applications. 

Ordering Captions and Enrichment Services

To order captions and enrichment services for a media entry
  1. Select My Media and then select the media (click the checkbox to select). You may select more than one media entry.
  2. Select Caption & Enrich from the Actions menu.
    The following screen is displayed:
  3. Select the Service Type - Machine or Professional.
  4. If you select Machine, select the Source Media Language from the drop down menu and click Submit.
    If you select Professional, the screen is expanded.
  5. Select the Source Media Language from the drop down menu.
  6. Select the Feature. Translation or Caption.

    For Translation:

    Select the Target Translation Language.
    Select the Turnaround time (TAT) from the drop down menu. The TAT options are set by your administrator.

    For Caption/Enrichment Services:

    Select the Turnaround time (TAT) from the drop down menu. The TAT options are set by your administrator.
  7. Add Speaker Names. This feature must be enabled by your system administrator. Relevant for Caption only
  8. (Optional) Add Instructions & Notes. This text box is relevant for Human Captions jobs only, and used by human editors & reviewers . ASR (machine captions) jobs can improve accuracy by using a dictionary. Please see below recommendations of what should be added to such notes:
    1. The general best practice is to use it for unique terminology and names, i.e., similar to an ASR dictionary, except using free text.  
      The notes are something that all Editors and Reviewers who work on the file will have available.
      Since it is people (and not a machine), it is best to limit it to the relevant items for that file, and not something like a 1000 word glossary.

    2. Comments such as “please pay extra attention to the following X, Y, Z in the first five minutes of the video…” are not effective because transcribers usually get only a portion of the file and, for them, every five minutes is the first five minutes.

  9. Click Submit. Requests are sent automatically. You will receive a message that your request has been received. The video will be updated with the captions/AD/Chapters when it's ready. 

In case there is an identical request, the system will display a message that an order was already placed for this video. See here.
