Transcripts are required for your videos. Transcripts help learners with hearing impairments understand audio content, and they are helpful for learners who speak other languages. You can allow learners to download transcripts so that they can read them offline. You associate a transcript with a video when you create the video component.
Timed transcripts in the SubRip Text (.srt) format are strongly recommended. Learners can select the Show transcript (”) icon in the video player’s control bar to show the transcript next to the video. The transcript automatically scrolls as the video plays, and learners can select a line in the transcript to jump to the point in the video where that word is spoken.
Learners can also choose to show the transcript file as overlaid closed captions for the video by selecting the CC icon in the video player’s control bar.
To create or obtain a transcript in .srt format, you work with a company that provides captioning services. When you choose a company, make sure that the transcripts you receive are in .srt format.

To prevent errors when you upload your video transcripts, edX recommends the following conventions for naming your transcript files.
By default, a .txt file is created when you upload an .srt file, and learners can download either the .srt or .txt transcript when you allow transcript downloads. Options to download these transcripts appear below the video. For more information about allowing transcript downloads, see Enable Video and Transcript Downloads.
You can also provide transcripts in formats other than the .srt format, such as .pdf, and you can provide additional transcript files in different languages. For more information about these options, see Specify Additional Transcript Options.
Historically, some courses used .sjson files for video transcripts. Use of .sjson files is no longer recommended. However, if transcripts in your course use this format, see Upload an .sjson File (Deprecated).
