The University of Texas Libraries Captioning and Transcription Service exists to ensure campus media is accessible to everyone. We prioritize video and audio content that directly serves those with hearing difficulties, but our services are available to the entire campus.

Additionally, the university has set aside some limited funds to cover captioning and transcription of certain pre-recorded materials. At this time, if content is directly related to an option I or option II course, the cost is covered.

As a content creator or owner it’s your responsibility to provide these essential accommodations to your audience. We’re excited to partner with you to make the process as easy and seamless as possible.

Send us your captioning, transcription or alignment requests.

Captions are on-screen text, synchronized to video or audio that provide additional or interpretive information. Captions mainly describe spoken dialog, but can also include non-verbal cues such as a “door closing” or music description.

  • Fee: $1.00 per minute
  • Glossary of caption file formats
  • Do-it-yourself options


Transcripts are similar to captions except there is no timing information. We can provide both captions and transcript, or one or the other. When only audio is available we usually provide a transcript. Transcriptions are typically delivered as Word, PDF and plain text, file formats.


Our alignment process takes your transcript and syncs every word to the audio or video provided. We do this by using an automated tool therefore a high quality verbatim transcript produces the best alignment.

  • Fee: Free if under 10 minutes
  • $0.10 per minute after that
  • Do-it-yourself options


There are often many details to consider when making video and audio fully accessible. Each situation can be unique. We’d love to connect and answer any questions you have about your individual needs. No project is too small. Please email to begin a conversation with us.

Caption File Format Glossary

  • CAP – This is a common subtitle/caption file format for broadcast media. It was developed by Cheetah International.
  • DFXP – This is a common format used for captioning Flash video. It’s a timed-text format that was developed by W3C and stands for “Distribution Format Exchange Profile”.

  • SBV – This is a YouTube caption file format that stands for “SubViewer.” It’s what you get when you download captions from YouTube. It’s a text format that is very similar to SRT.
  • SCC – Popular standard used for Line 21 broadcast closed captions, web media, DVD, as well as iTunes, iPods, iPads, and iPhones. It was originally developed by Sonic and stands for “Scenarist Closed Caption.” This file format can be useful for implementing additional formatting such as caption placement (vertical alignment, left, right, center) italics, bold, color and special characters. We don’t support complex formatting but can re-align captions to avoid overlapping on screen information.
  • SRT – This is the most common subtitle/caption file format. It is a text format that originated in the SubRip and stands for “SubRip Subtitle” file.
  • WebVTT – Common caption format for HTML5 media players.

YouTube explains caption formats for their platform. SCC is preferred but they support many other formats.
