How do I use the Caption Editor to edit a caption file?

In Canvas Studio, if your media includes a caption file, you can search and edit caption text in the caption editor. Caption files can be uploaded from your computer, or auto-generated.

Open Media

Locate the media you want to edit on the My Library page [1]. To search for media, click the Search icon [2].

  • Captions that are deleted cannot be recovered.
