With Canto, you can now manually upload subtitles to a video, and Canto will embed the file in the video. For now, Canto only supports VTT (WebVTT) or SRT files. See below for instructions on how to get started.
Note: you will need to reach out to your account manager to make sure to have the feature applied to your Canto library before getting started.
1) Select the desired video to add subtitles and click the Closed Caption icon at the top left
2) When the following window appears > select the language in the drop-down menu > click Upload to select your caption file > click Close and you're all set!
