Yes! edX course videos have interactive transcripts as well as closed captions. In some courses, the transcripts can also be downloaded.
Turn on Interactive Transcripts
You can turn on interactive transcripts for a video by clicking the double quotation (") button in the lower right corner of the video player. Interactive transcripts appear to the right of the screen, and keep pace with the video as it plays.
Turn on Closed Captions
You can turn on closed captions by clicking the closed caption (CC) button. Closed captions appear along the bottom of the video.
Choose Your Preferred Language
Some videos may offer captions and interactive transcripts in multiple languages. In this case, you can select your language preference by clicking the closed caption (CC) button and then select your preferred language. Auto-generated captions will be indicated atop the interactive transcript and offer the opportunity to provide feedback on quality. If you have urgent transcription concerns, click the Help button in the lower right hand corner of this page to contact Learner Support.
Download Transcript Files
Many courses offer downloadable transcripts in SubRip (.srt) or text (.txt) file formats. You can access the transcripts by clicking the download options below the video window under Transcripts.

SubRip (.srt) files can be opened by most word processor programs and browsers. Please note that .srt files include time information. If you prefer to download a file without the time information, choose the .txt format. This format does not include time data, and therefore might be easier to read.
To download a video transcript, below the video player, select the download option for the transcript file format that you want. In the dialog that opens, you can choose to open or save the transcript file.
