How do I upload a caption file to Canvas Studio media?
In Canvas Studio, you can upload caption files for your uploaded media and for media linked from YouTube and Vimeo. Studio supports SRT file types, the most common transcript file type, and VTT file types, a more mobile-device-friendly transcript file type.
For help creating a media caption file, you can use a captioning site such as Amara.
Note: Canvas Studio allows you to generate a caption file for your uploaded media. For media files that do not already have captions, learn about generating captions using the Caption Request tool.
In your Studio account, locate the media you want to view on the My Library page , or using the search field .
To open the media file, click the View link .
Click the Captions tab . Then, to upload a caption file, click the Upload button .
In the Upload Captions section, click the Language drop-down menu , and select the language used in your caption file. Then, click the Upload button .
If Studio does not display the caption language in the list, click the Custom link .
Enter the custom language name in the Language field , then click the Upload button .
Once uploaded, the caption file displays in the Manage Captions section.
A media file can have multiple caption files in different languages. However, a media file can only have one caption file per language.
To view options for a caption file, click the Options icon . You can edit , download , replace , or delete  any caption file.
Note: Caption files download in the same file format that they were uploaded in (SRT or VTT). After downloading, you can convert caption files into word processing files on most computers.
