How do I add captions to new or uploaded videos in the New Rich Content Editor in Canvas as a student?
You can easily create and upload caption files when you add video content in the New Rich Content Editor. The New Rich Content Editor is used in features that support the editor (Announcements, Assignments, Discussions, Pages, and Quizzes).
This lesson only applies to creating captions for videos created in or uploaded into Canvas. If you've created a video outside of Canvas that you want to share in your course, you can create captions using an external captioning tool such as Amara or YouTube.
Note: Users can view video captions in the Canvas apps. However, iOS devices can only display captions in WebVTT format. If you use another format besides WebVTT, users on iOS devices will not be able to display the video captions.
