EP provides faculty members several tools to record lectures and produce transcripts of those recordings for students. Captioning lectures is an inclusive measure for presenting course content to students.
Note: Unedited machine-generated captions should not be used in courses with an identified accommodation need. In these cases please work with Disability Services and the Help Desk to process Professional/Human captions to ensure the highest degree of accuracy.

Editing Captions for Lecture Videos (Kaltura)
As of January 2021, all new course developments and redevelopments use a professional human transcription service to caption lecture videos with 99% accuracy. If your course is older, it may instead use Automatic Speech Recognition (ASR) technology to produce machine-generated captions. These captions are generally 75-85% accurate and can improve over time as the program adapts to learn your voice. Captioning is automatic and does not need to be requested for lecture videos. No matter what type of captions your videos may have, they may require manual editing due to errors, specialized vocabulary, or heavy accents.
To edit captions for your videos, follow the steps below:
- Click My Media on the course menu in a Canvas course (it doesn't have to be the course that contains the video you want to edit).
- From the list of your videos in My Media, select the title of a video for which you would like to edit the captions.
- Scroll down and click the Actions button underneath the video (on the right side), followed by Caption & Enrich.
- Select the pencil icon next to the caption file to begin editing the captions. If there is more than one caption file, select the one with the most recent Request Date.
- On the Closed Captions Editor screen, you can edit captions as needed. Common errors to look for include garbled words, typos, and inaccurate proper names.
Features of the Closed Captions Editor include the following:
A. Search and Replace
Search for words or phrases within the captions. Use the Replace function to trade specific words or phrases for others throughout the transcript.
B. Add Speaker
Attribute particular captions to a specific speaker. To add a speaker, highlight one (or more) captions in the Text Editor, type a name in the Add Speaker text box, and click Add.
C. Timestamp and Text Editor
Revise the text incrementally by editing words or phrases that appear incorrectly.
D. Video Preview
Play and pause the video as you edit captions. By default, the Autoscroll function is turned on, allowing the transcript to scroll as the video plays.
