Overview

This has been a long awaited feature that we're excited to announce! Captioning your videos help your learners improve comprehension of the materials, draw closer attention to, and memory of the video. They are especially useful for non-native learners, and those who have accessibility needs. The ability to caption your videos is a shift to a model of universal design for learning and inclusion. This is a model that explores how we can benefit students by being more intentional and accessible in our course design. 


The added ability to easily caption your videos within Kaltura allows all learners to engage equally. Machined captioning takes your video and feeds it to a machine that will automatically transcribe your video into captions without the need of a human with a turnaround time of about 30 minutes. Its accuracy is 75-80% accurate based on variants. You can also edit the captions directly within Kaltura using the caption editor.


Please note: When a request for media captioning is submitted below, a copy of the media file is made on servers in the United States.  This is for temporary, machine-to-machine, processing only; once the caption file is completed the media copy is immediately deleted from the US server.  Note: it may be possible for the media copy to be accessed by a person during this process.


Note: Only videos that are uploaded to Kaltura are available for captioning. YouTube added videos are not available for auto-captioning through Kaltura.
