Choosing a Captioning Company

The captioning company that you use to create captions for your videos will depend on the types of videos that you use in your courses.  See specific instructions below based on the type of videos that you use.


If you use Mediasite through DELTA, the IT Accessibility Office will help you coordinate your video captioning with the DELTA staff.  We will need to know Mediasite channel your videos are on and which videos need captioning.

  1. If you create your own Mediasite presentations by uploading video or recording from your desktop make sure the presentations are published to a Mediasite channel outside of your private/drafts folder. can provide tutorials on how to publish or move presentations to a channel.
  2. Please be aware if you edit (ex. trim part of a video) a captioned Mediasite presentation the captions will no longer be correct.  There is a Mediasite captions editor. If you edit a presentation after it has been captioned you will be responsible to edit the captions as well. can provide tutorials on how to use the Mediasite captions editor.
  3.  If you are working with to submit Mediasite presentations for captioning please be mindful of the turnaround time. If you contact them after business hours they may not respond until the following business day.


If you host videos that you have created on Youtube, you may use a number of different captioning companies.  If the total cost is over $5000, you can use one of the vendors on our Convenience Contract. If the total cost is less than $5000, you can use any provider you want, pursuant to University regulations, but you can also use those on the Convenience Contract.  If you use these companies, make sure to mention the convenience contract number with your order. is another popular option for captioning your videos hosted in YouTube because it is less expensive and syncs with your YouTube account.

Other Online Hosting Solutions

If you are using online hosting solution, other than Mediasite or YouTube, first make sure the video player provided is keyboard accessible to students.  If so, follow the instructions for YouTube.

Online Videos that You Do Not Own

Captioning videos that you do not own can be more complicated.  It is best practice to first check to see if there is a version of the video that has captions on another platform and/or contact the company that owns the videos and ask them to provide captions.  Surprisingly, many companies will provide the captions if you request them for educational reasons.

If neither of these options work, you should use Automatic Sync’s Smart Player.  This allows for captioning of videos owned by other individuals for educational purposes and has a variety of other great features.


If your video is on an older DVD or VHS tape that does not include captions, you may use Automatic Sync or 3PlayMedia, which are both vendors on our Convenience Contract.  If you use these companies, make sure to mention the convenience contract number with your order.
You might also consider contacting the Digital Media Production team in the NC State library for help digitizing your media before requesting captions.
