When it comes to making videos accessible, two common methods are often used: SDH subtitles and closed captions. While they may seem similar, they serve different purposes and have distinct differences.

Closed captions (CC) are a crucial tool for ensuring that individuals who are Deaf or hard of hearing can fully enjoy and understand video content. CCs provide a text representation of the audio, including important sounds that move the plot along, clarify information, and show key aspects to characters. This includes dialogue, music, sound effects, and even silence. By law, some media platforms are required to include closed captions to ensure equal access for everyone.

On the other hand, SDH (Subtitles for the Deaf and Hard of Hearing) subtitles focus more on providing a text representation of spoken dialogue only. They do not include sounds or music, unlike CCs. SDH subtitles are often used in situations where the primary audience is not deaf or hard of hearing, but may benefit from additional support.

One key difference between CCs and SDH subtitles lies in their purpose. Closed captions aim to provide a comprehensive representation of the audio, including important sounds that enhance the viewer's experience. SDH subtitles, on the other hand, focus solely on providing a text representation of spoken dialogue for the benefit of those who are deaf or hard of hearing.

Another significant difference is in how they are created. Closed captioning technology began in mid-century broadcast television and has evolved over time to include advanced tools and software. Captions are synchronized with the timing of the video, ensuring that the text accurately represents the audio. In contrast, SDH subtitles typically involve a manual process of transcribing dialogue into text.

In summary, while both CCs and SDH subtitles serve the purpose of making video content more accessible, they differ in their scope and focus. Closed captions provide a comprehensive representation of the audio, including important sounds that enhance the viewer's experience, whereas SDH subtitles focus solely on providing a text representation of spoken dialogue for those who are deaf or hard of hearing.

By understanding the differences between CCs and SDH subtitles, content creators can make informed decisions about how to ensure equal access for their audiences. Whether it's closed captions or SDH subtitles, both methods play a vital role in making video content more inclusive and enjoyable for everyone.
