How to Edit Video Captions on YouTube
By Sarah Wendorf (Instructional Designer) & Jeff Tranchemontagne (Multimedia Specialist)
Accurate video captions are a necessity for some and a benefit to all. They are not only good for Universal Design for Learning, but they are also mandated by accessibility laws in Ontario for the public sector.
When you post videos to YouTube for your students to watch as part of their learning, YouTube’s automatic captioning service will create automatically-generated captions for your video. However, these automatic captions are not always accurate. This may disadvantage some students who rely upon, or prefer to watch videos using captions. They may miss out on important terminology, names, dates, and other information that may be missed when spoken words are not captioned accurately. As well, poor audio quality, accents, microphone feedback, or background noise may add further inaccuracies.
Luckily, you are able to quickly and easily make edits to your video captions within YouTube’s video editor. This is only possible for videos that you upload yourself and have editing access to.
It may take a few hours for YouTube’s automatically-generated captions to appear on your video. Once that process is complete, follow the steps below to learn how to edit your video captions on YouTube.
