Closed captioning is the process of displaying text on a screen or other visual display to provide a textual alternative to the audio portion of a video or broadcast; WHAT.EDU.VN offers accessible information to help understand and utilize closed captions effectively. By understanding the nuances of closed captioning, including its creation and implementation, individuals and organizations can enhance accessibility and engagement for a wider audience. Delve into the specifics of captioning, subtitling, and transcription.
Closed captioning is a textual representation of the audio in a video or television program, displayed on a screen for viewers. Unlike subtitles, which typically only transcribe dialogue, closed captions include not only spoken words but also other relevant sounds, such as background noises, music cues, and speaker identification. The primary purpose of closed captioning is to make content accessible to individuals who are deaf or hard of hearing, but it also benefits those who are learning a new language, watching videos in noisy environments, or simply prefer reading along with the dialogue.
Closed captions are encoded into the video signal and can be turned on or off by the viewer using a decoder or built-in settings on their device. This feature distinguishes them from open captions, which are always visible and cannot be disabled.
2. Why is Closed Captioning Important?
Closed captioning is crucial for several reasons, spanning accessibility, legal compliance, and audience engagement:
- Accessibility: Closed captions make video content accessible to individuals who are deaf or hard of hearing, ensuring they can fully understand and enjoy the material. This aligns with the principles of inclusivity and equal access to information.
- Legal Compliance: In many countries, laws and regulations mandate closed captioning for broadcast television, online video content, and public events. For example, the Americans with Disabilities Act (ADA) requires closed captioning for certain types of video programming in the United States.
- Enhanced Comprehension: Research indicates that closed captions can improve comprehension and retention, especially for viewers learning a new language or those with cognitive disabilities. A study by the Journal of the Academy of Marketing Science found that closed captions enhance brand recall, verbal memory, and behavioral intent.
- Improved SEO: Search engines cannot “watch” videos, but they can analyze the text in closed captions. Adding captions to your videos can improve their search engine optimization (SEO) by providing valuable keywords and context, making them more discoverable.
- Increased Engagement: Many people watch videos without sound, particularly on social media platforms. Facebook has reported that 85% of its videos are watched without sound. Closed captions ensure that these viewers can still understand the content, increasing engagement and watch time.
- Versatile Use: Closed captions are beneficial in various environments, such as noisy public spaces, libraries, and offices, where audio may be disruptive or unavailable. They also assist individuals with learning disabilities or those who prefer reading along with the dialogue.
3. What are the Key Differences Between Closed Captions and Subtitles?
While closed captions and subtitles both display text on a screen, they serve different purposes and have distinct characteristics:
| Feature | Closed Captions | Subtitles |
|---|---|---|
| Purpose | Primarily designed for viewers who are deaf or hard of hearing, providing access to all audio elements. | Designed for viewers who can hear the audio but need a translation or clarification of the dialogue. |
| Content | Includes dialogue, speaker identification, and descriptions of other relevant sounds (e.g., music, sound effects). | Primarily includes dialogue, often translated from the original language. |
| User Control | Can be turned on or off by the viewer using a decoder or device settings. | Typically always visible and cannot be disabled (open subtitles) or can be selected by the viewer. |
| Encoding | Encoded into the video signal and require a special decoder or player to display. | Often provided as a separate file (e.g., SRT, VTT) that is loaded alongside the video. |
| Target Audience | Individuals who are deaf or hard of hearing, language learners, and viewers in noisy environments. | Viewers who speak a different language than the original audio or who need clarification of the dialogue. |
4. How are Closed Captions Created?
The process of creating closed captions involves several key steps:
- Transcription: The audio content of the video is transcribed into text. This includes dialogue, speaker identification, and descriptions of significant sounds. A trained transcriptionist typically takes four to five hours to transcribe one hour of normal audio or video content.
- Timecoding: The transcribed text is synchronized with the video, assigning precise start and end times to each caption. This ensures that the captions appear on screen at the correct moments.
- Editing: The captions are edited for accuracy, clarity, and readability. This includes correcting errors in grammar, spelling, and punctuation, as well as ensuring that the captions are properly formatted and do not obscure important visual content.
- Encoding: The completed captions are encoded into the video file or a separate caption file (e.g., SCC, SRT, VTT). This allows viewers to turn the captions on or off as needed.
- Quality Control: The captions are reviewed to ensure they meet quality standards for accuracy, synchronization, and readability. This may involve both automated checks and human review.
5. What are the Different Types of Closed Captioning?
There are several types of closed captioning, each with its own characteristics and applications:
- Real-Time Captioning: Used for live events, such as news broadcasts, sports games, and conferences. Real-time captioning involves a stenographer or trained captioner transcribing the audio in real time and displaying the captions on screen with minimal delay.
- Offline Captioning: Created for pre-recorded video content, such as movies, television shows, and online videos. Offline captioning allows for more time and resources to ensure accuracy and quality.
- Open Captioning: Also known as “burned-in” captions, these are always visible on the screen and cannot be turned off by the viewer. Open captions are often used in public spaces, such as airports and restaurants, where it is important to ensure that everyone can understand the audio content.
- EIA-608 Captioning: An older standard for closed captioning used in North America for analog television broadcasts. EIA-608 captions are encoded in line 21 of the vertical blanking interval of the video signal.
- EIA-708 Captioning: A newer standard for closed captioning used in North America for digital television broadcasts. EIA-708 captions offer more features and flexibility than EIA-608 captions, including support for multiple languages, fonts, and text sizes.
6. How Much Does Closed Captioning Cost?
The cost of closed captioning can vary widely depending on several factors, including the length of the video, the complexity of the audio, the turnaround time, and the vendor or method used.
- In-House Captioning: Organizations may choose to create closed captions in-house using their own staff and resources. The cost of in-house captioning includes the salaries of transcriptionists, editors, and project managers, as well as the cost of software and equipment. A conservative estimate for in-house, large-scale closed captioning operation averages $165 per hour of video, which is more than double the cost of hiring a professional closed captioning service.
- Professional Captioning Services: Many companies offer professional closed captioning services. The cost of these services typically ranges from $1 to $27 per minute of video, depending on the vendor, quality, and turnaround time. Opting for a vendor that uses a mix of technology and human editing can provide a cost-effective and high-quality solution.
- Automatic Speech Recognition (ASR): ASR technology can be used to generate automatic captions for videos. While ASR is often cheaper than human captioning (averaging around $0.25 per minute), the accuracy may be lower, requiring additional editing and quality control.
- Crowdsourcing: Some companies use crowdsourcing platforms to create closed captions. While this can be a cost-effective option, it may also result in lower quality and inconsistencies.
7. What are the Legal Requirements for Closed Captioning?
