We strongly recommend that you associate a timed transcript with your video. Transcripts can be helpful for students whose first language isn't English, or who can't watch the video or want to review the video's content. The transcript scrolls automatically while your video plays. When a student clicks a word in the transcript, the video opens to that word. You can also allow your students to download the transcript so that they can read it offline. You'll associate the transcript with the video when you create the Video component.
To create or obtain a transcript, you can work with a company that provides captioning services. EdX works with `3Play Media <http://www.3playmedia.com>`_. `YouTube <http://www.youtube.com/>`_ also provides captioning services.

.. note:: Make sure that all your transcript file names are unique to each video and language. If you use the same transcript name in more than one Video component, the same transcript will play for each video. To avoid this problem, you could name your foreign language transcript files according to the video's file name and the transcript language.
For example, you may have two videos, named 12345abcde.mp4 and 54321edcba.mp4. Each video has a Russian transcript and a Spanish transcript. You can name the transcripts for the first video 12345abcde_ru.srt and 12345abcde_es.srt, and name the transcripts for the second video 54321edcba_ru.srt and 54321edcba_es.srt.
