Kaltura Multimedia: Adding Closed-Captions (CC)

Kaltura Reach Machine Captioning

Machine captioning is fast, simple, and decently accurate (~80%) but may struggle with acronyms and industry-specific words. However, video owners can easily correct machine transcripts. (These instructions require that a video be uploaded to the Kaltura Media Gallery within a course and is part of our series of Kaltura instructions.)

Kaltura Reach will create machine captions for a video in English, French, German, Russian, Spanish, and Vietnamese if that is the spoken language in the video. However, it does not translate the spoken language into another language.

As of 2023 Kaltura Reach machine captioning is enabled by default and captioning should only need to be requested on older videos within Kaltura or if the spoken language of your video was not English.

Request Human Captioning

For the best accuracy you can submit a request for human-captioning for your video.

NOTE: Clackamas Community College uses CaptionSync resources provided to us for free from the state to process these and if we don’t use them we lose them. Don’t hesitate to request Human Captioning well in advance of possible needing it!

If your machine captioning is too inaccurate you can submit a form to request a video be captioned. In order to process your request we need the Video ID. Follow these steps to find this information.
