What is subtitle captioning?

Subtitle captioning is the process of transcribing spoken dialogue, sound effects, and relevant audio information into text that appears on screen during video content. This helps viewers understand the audio, particularly those who are deaf or hard of hearing or watching in a different language. Subtitle captioners listen to audio tracks and create accurate, synchronized captions that match the timing of the speech and sounds in the video. The captions must be readable, concise, and properly timed to ensure a smooth viewing experience.
