I didn't like some of the other answers, which led to a trial version of an overpriced software, a software that did not make it clear you were downloading a trial version. I found this link: http://features.en.softonic.com/how-to-burn-subtitles-to-a-movie-on-a-mac Those instructions involve the use of ffmpegx, which is a free software, was easy to use, and performed the task pretty quickly.
