At ASU, all online videos must be captioned. Captions are synchronized transcriptions of audio content, displayed as an additional track or burned into a video.

- How to write captions
At ASU, live streaming videos at a minimum must have auto-captions. See how to enable:
If someone with a hearing impairment requests an accommodation at a live event, please see SAILS for help arranging these.
At ASU, captions must be provided for all recorded videos consumed by students, staff, or the public in digital formats, such as on websites, presentations, social media and trainings.
Captions may be either professional human-generated transcripts (see SAILS for help arranging these) or edited auto-generated captions (see below).
Because human transcription services can be expensive, many people choose to add free auto-generated captions, then edit them.
If you add auto-generated captions, you must edit them. Unedited auto-captions do not satisfy the requirements of the Americans with Disabilities Act (ADA) or Section 508 of the Rehabilitation Act.
See the following for instructions for enabling and editing auto-captions on a number of platforms.
- MediaPlus: Built-in auto-captioning is coming soon. Meanwhile, you can request auto-generated captions. You can also manually upload caption files (VTT) for videos hosted in MediaPlus.
- YouTube: Most videos uploaded to YouTube are automatically auto-captioned. Learn how to edit those captions. Once edited, you can download captions as an SRT and VTT file for use on other platforms.
- Wistia: See instructions and the form for requesting auto-captions.
- Happyscribe: Offers a free transcription editor. They also have human transcription services for $2.00 per minute, as well as auto-generated captions at $0.20 per minute.
- Vimeo: For paid members, videos will be automatically captioned during the upload process. You must edit the transcript for accuracy.
- Otter: Provides auto-generated captioning for $8.33 per month and 6000 minutes.
- Happyscribe: see above.
- Camtasia: Manually add captions or use the integrated Microsoft speech-to-text engine to add auto-generated captions in Camtasia.
- Windows Speech Recognition: Use this free speech recognition software built into Windows to generate a transcript.
- Google Docs Voice Typing: Use this free "voice typing" software in Google docs (available in the Chrome browser only) to generate a transcript.
If you don't have the time or resources to edit auto-captions or create captions for a recorded video, there are many paid human transcription services available. In some cases, it may make sense to take advantage of a paid service to edit auto-generated captions or to transcribe a recorded video.
If you'd like to use a library-owned or -licensed video in class or on Canvas that is not yet captioned, add it to your ASU Library Resource Organizer in Canvas, and the library will automatically caption it. Or you can submit a Streaming Video Reserve request form, and the library will activate the tool in Canvas and add the item for you.
See more information about library streaming videos.
If a request for an accommodation is made, provide Communication Access Realtime Translation (CART) captioning or American Sign Language (ASL).
- If a student who is registered with SAILS requests an accommodation, notify SAILS and work with the student's Access Consultant to meet the student's needs.
- If an employee requests an accommodation, contact the Office of Diversity, Equity and Inclusion.
- If a member of the public requests an accommodation, contact the Manager of Deaf and Hard of Hearing Services for recommendations of CART and ASL vendors. Fill out a request form:

The recommended guide to writing captions is the Department of Education-supported Described and Captioned Media Program (DCMP) Captioning Key. The BBC's Subtitle Guidelines is also good.
