How to Add Closed Captions and Subtitles to Kaltura Online Course Videos
Kaltura is a Saas-based open-source video platform that’s useful in creating videos for educational or business purposes. Businesses, schools and other enterprises use Kaltura videos to enhance online learning and training experiences. As more people transition to remote school and work situations, video platforms such as Kaltura will become even more useful.
There are a lot of ways to make online course videos more dynamic. Knowing how to add captions in Kaltura is an important one. Captions and subtitles help make your video content more accessible for diverse audiences and easier for just about anyone to understand. Here’s why and what you need to do to get started using Kaltura closed captioning.
The Benefits of Using Kaltura Closed Captions
Kaltura closed captioning makes it easier for your audience to understand the content of your videos in a number of key ways.
Different people process information in different ways. Some people prefer to process words they can read or find captions easier to focus on, even if there’s accompanying audio. Incorporating Kaltura closed captioning also helps minimize potential misunderstandings that could occur if someone watching the video mishears a word or a phrase. Simply stated, it’s another way to make your videos user friendly.
Accessibility for People With Disabilities
The American Disabilities Act (ADA) requires colleges, universities and other learning institutions to make accommodations for people with disabilities. This includes people with hearing impairments. Kaltura closed captions show the words in print across the screen, so the content is still useful to someone who is unable to hear the audio.
This is a legal requirement. But it also makes video learning even more accessible than even attending an in-person class for a lot of people. This may be a key reason a person chooses online courses when given the option.
Translation for Non-Native Speakers
Business and learning have gone global, and not everyone speaks the same native language. You can use Kaltura closed captioning to add translated subtitles to your online course videos, making them accessible and understandable to audiences from around the world. This can be extremely useful if you’re using Kaltura videos to teach people who have immigrated from other countries or for international audiences.
How to Add Captions to Kaltura Videos
You can add captions and subtitles to Kaltura online course videos by using the Kaltura Management Console, or KMC. You can upload multiple subtitle and caption files for your video.

1. Select your video entry.
Click on the “Content” tab. Then, choose the appropriate video entry.
2. Assign the caption file.
Click on the “Captions” tab. Add a label for your caption file. For instance, if you’re going to have versions in several languages, you may want to label them by language.

3. Upload or Link to the Caption File.
