How do I create a caption file using the subtitle creation tool as an instructor?
When you record a new video or upload an existing video in Canvas, you can upload a caption file for your users. If you do not have a caption file, you can use the subtitle creation tool to create the file for your video.
Once you have created and downloaded your caption file, learn how to add captions to Canvas videos.
Note: Canvas must render the video and create a URL link before you can create a caption file. If you try to add subtitles and the subtitle creation tool is not yet available, try accessing your video later.
