A transcript is simply a text version of words spoken in a video that does not necessarily synchronize with video content. Captioning converts all audio content in the video (words spoken, sounds, background noises, singing, etc.) into text that is arranged to display synchronously with video content. Captioning is required for accessibility for viewers who are deaf or those experiencing hearing loss.
Some software has captioning built-in, but it's pretty rare. However, hosting locations are getting better about making it part of their upload process or after upload.
Captioning options:
- YouTube - You can edit automatically created transcriptions and add captioning in the YouTube Creator Studio to make accessible video content. See the edit or remove captions article on YouTube's help section for assistance.
- Panopto - Allows you to upload captions after recording
- Google Slides - Can perform live captioning during the presentation of slides
