Captioning videos is important for accessibility reasons as well as Universal Design for Learning principles. There are various methods to auto-generate captions that can be downloaded and shared on a University of Toronto hosting platform.
These programs use speech recognition to generate captions:
- Classic Microsoft Stream
- The new Stream (OneDrive/Sharepoint)
- Zoom and the Zoom Quercus Integration
Overview of Captioning & Hosting Tools
University of Toronto offers several ways to generate recordings. We recommend using Microsoft Stream or Zoom for their captioning capabilities.
Please read below on how to caption videos created by the various institutionally-available recording tools and how to share captions on those platforms.
- Microsoft Teams recordings with transcriptions that are saved to OneDrive or SharePoint can be viewed along with the transcription; however, the captions can’t be edited for accuracy.
- MyMedia does not have a method for generating captions however an caption file from Stream or Zoom can be uploaded to the site along with a video.
