Closed Captions - Boost Your Content Quality!

Crucial for elevating your content experience, closed captions present text on video or audio, transcribing spoken words and describing sounds. Viewers can toggle them, assisting those who are deaf or hard of hearing, those learning a new language, or in noisy environments, allowing viewers to follow along without needing sound. While often auto-generated, using caption generator software enhances accuracy, ensuring a precise and inclusive viewing experience.

Frequently Asked Questions

What's the difference between subtitles and closed captions?

Chevron down icon

Subtitles translate spoken dialogue into another language for viewers who understand the audio but not the language. They exclude non-dialogue sounds. Closed captioning is for the deaf or hard of hearing, detailing all audio elements, including dialogue, sound effects, and speaker changes, in the same language as the audio. Subtitles are for translation, while closed captions ensure accessibility.

Why are closed captions called closed?

Closed captions are termed "closed" because they can be turned on or off by the viewer, unlike "open captions," which are always visible and cannot be turned off.
