About Audio Description

• Audio description (sometimes referred to as Described Video) is provided by a trained describer that provides descriptions of the visual components of the video. Audio description makes video accessible to blind/visually-impaired persons who would otherwise miss out on information presented visually. This information is synchronized with the video, but provided in a separate sound track.

• For a full description and example of audio description, see the Penn State whitepaper titled An Introduction to Audio Description in Higher Education Video Content

Captioning of Recorded Videos from Popular Platforms

Many of our campus video and web conferencing platforms have some level of support for automatic captioning, but in most cases we recommend using Kaltura as your primary video storage and captioning tool. Please remember that while machine-generated captions can be a time-saver, they are error-prone and always require editing/clean-up.
