Captioning Information

The campus has implemented new rules for course materials requiring all course content to be accessible. This means that all video content needs to have closed captions. While there are numerous questions about these new rules that we may not be able to address (i.e. funding), we are here to help you through the technological aspects of the process. If you would like to discuss in greater detail or have pressing questions, feel free to stop by the Instructional Design suite in the Knowledge Center (411) or email

The matrix below shows some of the resources available and the trade-offs in terms of cost, time and technical difficulty. As you can see, unfortunately, there is no "silver bullet" for creating captions for your video content.

3Play Media - How to Setup a Departmental Account

If you would like to set up an account with 3Play to have your captions created for you, contact Ed Huffman ( 3Play offers integrations with our video server, Kaltura, and our lecture capture system to make the process less complicated. This service is one of the easiest ways to get your captions completed, but is also one of the more costly. You can view some of the service options available on their website:


YouTube allows you to use their automatic captioning tool to create rough captions for your video files. These captions require editing before they can be used for course materials because the accuracy is limited. That being said, it is a cost effective way to create captions for your video content. The links below provide instructions on how to create captions using YouTube and how to upload those caption files to Kaltura.


You can download the Aegisub software here. It is free software and allows you to manually create subtitles. There is no automation in this process, so it is the most time consuming and complicated but it is the cheapest option in regards to money spent (but not time spent).

How to Turn on Closed Captions When Showing a DVD in Your Classroom

In most of the centrally schedule classrooms on campus, you will use the computer to play a DVD. The default software for playing DVDs in the classroom is VLC media player.
