Adding captions to YouTube videos makes your videos more accessible to people who can’t follow along with the audio either because of a disability or because they speak a different language. Some video tools like Adobe Captivate already have functions built-in that allow you to create subtitles or captions. From there you can simply upload the video. Alternatively, if you have already completed your movie and simply need to add Captions/Subtitles or if you already uploaded it to YouTube, you can still create them as well.
