Accurate closed captions are included for video files. Without closed captioning, the information in a video segment may be entirely lost to people with disabilities. For video files to be accessible, they must include accurate closed captioning for video files. Closed captioning should be synchronized with the timing of the video. Captions should be edited to 100% accuracy to meet ADA guidelines. Note: Auto-generated captions are generally not accurate enough to meet ADA guidelines. It is recommended to review video captions for accuracy before incorporating into course(s) or presentations. |
For videos created using Kaltura:
For YouTube videos you do own: Use YouTube's captioning tool to caption videos. The auto-generated captions are not accurate enough to meet accessibility guidelines; therefore, captions will need to be reviewed and edited. For YouTube videos you do not own: Kaltura users may add a YouTube video to their My Media in order to utilize Kaltura’s closed captioning features. Note: This method does not save a copy of the YouTube video to a user’s My Media. The YouTube video must remain available on YouTube or it will not work within Kaltura. |
Accurate transcripts are included for audio files. Without a transcript, the information in an audio segment may be entirely lost to people with disabilities. For audio files to be accessible, they must include an accurate transcript. Audio files may include a podcast, MP3, etc. Transcripts can added as an additional attached file or as a link if there is an existing resource. Text transcripts should be 100% accurate to meet ADA guidelines. |
To create a transcript: Method 1: Hand type a script for the audio file. Method 2: Use Kaltura to either record or upload an audio file, then request captions using the closed caption feature.

Audio and/or video files are not set to autoplay and do not loop. Autoplay is problematic for users using screen readers, as screen readers read the text on the page aloud; having an audio/video file autoplay can cause both the video and screen reader to play at the same time. |
For Kaltura videos: Kaltura video and audio files automatically enable user control that does not allow looping or auto-play. For YouTube videos: Autoplay is viewer controlled and can be turned off by doing either of the following:

Images or other multimedia are not prone to induce seizures. Animated images that contain flashing or contrasting lights or patterns can lead to seizures for people that suffer from photosensitive epilepsy, which is a very serious and potentially life-threatening condition. In addition, animated images with these characteristics can be generally unpleasant to look at, even for those not prone to seizures. |
Do not use blinking or flashing media. Use a different media file or image. |
