what is CAPTIONING?

Captioning is a process that involves dividing transcript text into small parts, known as “caption ,” and time-coding each frame to synchronize with the audio of the video. The output of captioning are captions which are typically located at the bottom of a video screen.
Captions are similar to television subtitles and give people who are deaf, deafened or hard of hearing access to live performance. The actors’ words appear on an LED caption unit (or units), placed next to the stage or in the set, at the same time as they are spoken or sung.
Captioning is a very specialized type of transcription. It takes a highly skilled typist (usually with court reporting certification or experience) to do this work, particularly for the real-time captioner. Those with these skills and experience can earn a good living from home working as a captioner.
