Captions Files

Caption files contain time coded text of what is said in a video or audio file.  The caption file and media file are synced using a host platform, such as Kaltura, YouTube, or Vimeo. Captions often appear at the bottom of a video and can be turned on or off.

Captions are useful for students and employees who are deaf/hard of hearing and/or whose native language is not English.

ATI will provide a caption file when videos are hosted outside of Kaltura. If videos are hosted within Kaltura, the caption file will be uploaded to the requested video.

Upload Captions Files and DIY Captions

Recorded Zoom meetings/lectures provide a .vtt caption file, which can be uploaded into Kaltura after the video is uploaded into Kaltura.  The caption file must be downloaded from Zoom.  Zoom recordings are automatically removed from the Zoom Cloud 120 days after recording date.
