How do I create a caption file for an external video?
Canvas recently introduced a new page design called the New Canvas User Interface (UI). Depending on your Canvas view, your page design may vary from the images shown in this lesson. However, the functionality and location of the components remain the same.
Note: You cannot add a closed-captioning file to an online video if you are not the owner.
Create Caption Files
Amara is the same service referenced in our lesson about creating captions in Canvas. The difference is that with YouTube and other third-party sites, your video is already uploaded to the Internet, so to create captions, all you need is the URL to the video.
Note: Your video must be publicly accessible for the URL to work and stored on a supported third-party site.
Upload Caption Files
Most online video sites that support closed captioning will have a link to upload caption files. Each site will have its own requirement for the type of file required.
YouTube accepts a variety of file types, the most common being .srt, .sbv, and .txt. If you grant them permission, sites such as Amara and CaptionTube can link directly to your YouTube account and add the caption files directly to your video.
