What is “Video Captions”?

Captions are a text form of audio information in video and animations. This includes the words that are spoken, who is speaking when it is not evident, and important sounds like music, laughter, and noises. Captions must be synchronized with the visual content to contextualize them.

What are the additional benefits?

What needs to happen for this to work?

Captions must be made available with pre-recorded and live video content. Voice recognition software can help create captions for some type of videos. Sometimes such voice recognition software is built into the computer or social media platform. Automatically-generated captions often need editing. For many languages there are captioning services, often also remote services.

Video Captions
Video isn't just about pictures, it's also about sound. Without the audio, you would have to guess what this film is about. A man sat at a desk starts watching a video on his computer.
[no sound] The video on his computer shows a person speaking to the camera. It is playing with no audio.
Frustrating isn't it? Not knowing what's going on. That's the situation for everyone who can't hear. The man watching the video has a hearing aid.
Captions make videos accessible. He turns on captions for the video playing.
Which is also handy for people who want to watch video in loud environments. Another man is watching the captioned video with a group of people chatting away next to him.
Or where you need to be very, very quiet. Turns out that they are in a library. The group is shushed by the librarian.
Web accessibility: Essential for some, useful for all. The video is shown playing with the captions on.
