Video and Multimedia Tools

Resources and links are for information purposes only, no endorsement implied.

Accessible audio and video content must have equivalent transcripts and/or captions. Descriptive text transcripts or audio descriptions should also be used for video. Often, hiring a vendor to transcribe audio and add video captions is more cost effective than doing it in-house, but there are tools available to help.

Audio Descriptions

An alternate caption track enables low-vision or blind users to experience visual cues and/or action sequences by listening to a narration of events.

Captions and Transcripts

Many applications and vendors feature both transcription and captioning services. Resources listed may provide transcription, captioning or a combination of both.
