Captioning is the art of transcribing the audio portion of a video, program, or event into text and displaying that text on a screen. These captions can appear on a television, movie, computer, or mobile device.
Captions largely are used by members of the deaf and hard-of-hearing community, and captioning a program, conference, or event goes a long way towards making it inclusive and accessible to all.
The popularity of captions has grown in recent years as both video and captions have expanded well beyond the reach of traditional television and media. People also have become more aware of this essential service and thanks to laptops, tablets, PCs, and smartphones, captioned video can be viewed literally anywhere – at work, on the commute home, on the beach, or in a crowded bar.
Closed Captioning and Open Captioning
Captions can be produced in two ways:
The key difference between the two is that the viewer can turn closed captions on and off, while open captions always display on the screen and cannot be turned off.
Closed captions are created as a separate text file and then combined and synced with a video, which gives you the ability to switch them on and off. The captions are passed through decoders which, since 1993, have been required in all television sets 13 inches or larger sold for use in the United States. Because it’s a separate file, content creators and caption vendors like us can quickly and easily edit, correct, and re-upload closed caption files if an error pops up or something changes in the video between when it was captioned and when it airs.
Open captions, on the other hand, cannot be switched off. They are hard-coded into the actual video and appear on the screen at all times. This eliminates the need for a decoder. However, because the captions are burned into the video, editing open captions for errors or updates often means recreating the entire video file. Some training videos contain open captions, and some movie theaters will show films with open captions for all.
We’ve been the industry leader since 1986.
Trust our unmatched experience, and rest assured that you will receive the highest quality product and superior customer service.
Traditionally, captions have been created by highly trained professionals who understand the nuances of language, and who bring human sensitivities and contextual awareness to the captioning table. VITAC strongly believes in this essential human element in creating captions. Our captioners are recruited, trained, tested, and reviewed to ensure professional, reliable, round-the-clock, and secure customer service.
That being said, technology continues to play a greater role in all facets of life, and the captioning sector is no exception. As automatic speech recognition (ASR) programs such as Siri and Alexa are becoming more prevalent, some are promoting them as an alternative captioning option.
The appeal of ASR is that the software provides instant, realtime captions and perhaps most importantly, an inexpensive or free solution, as in the case of YouTube. It’s a relatively simple procedure that checks most of the right boxes, except for the most important one – providing accurate, reliable, error-free onscreen information.
Though speech automation certainly has a role in creating captions, the programs need a human hand guiding and assisting it. The problem in quality lies with “unassisted” automatic captions, where a human is not involved.
Even the most advanced speech recognition programs lack human intelligence and are, in essence, a guess by machines at the spoken word. Without having a human eye or ear monitoring the machine for items such as accuracy and completeness, ASR can fail to meet expectations.
Live or realtime captions are created as the program is being broadcast or the event is being held. Examples of live captioning can be found on:

There is no doubt that captions are a key to ensuring that your video content is accessible to all people whenever and wherever they want to watch. But it also goes a long way towards making your videos more searchable, digestible, and engaging.
Accessibility Anytime, Anywhere
Captions make television shows, movies, and online videos accessible to audiences who would not otherwise be able to enjoy the content. There are nearly 50 million Americans in the deaf and hard-of-hearing community alone who might be interested in the videos you share. When you also include the ever-growing number of Americans who watch videos in places where it’s impossible to hear the audio — on public transit, in a busy restaurant, on a noisy gym treadmill, or at the library — the number of people who rely on the accessibility captions provide grows substantially larger.
Improved Retention and Engagement Rates
Studies have shown that viewers retain 95% of a message when they watch it as a video compared to 10% when reading it as text, and audiences are about 10 times more likely to engage, embed, share, and comment on video content than non-video blogs or social posts. Adding captions to videos — as many schools, universities and businesses have discovered — has been shown to make the content more engaging, improving the retention and overall learning experience for all viewers.
Video content helps boost a site’s Search Engine Optimization (SEO) ranking, with research finding that having video on your page drives a 157 percent increase in organic traffic from search engines. Often, though, SEO programs aren’t properly able to “read” videos unless they contain some sort of text that can be indexed. Captioning videos allows search engines to translate audio to text. By adding captions, you are essentially embedding transcripts of your content in the video file’s metadata, pulling all the video’s searchable keywords to the forefront and in the process, boosting your search rankings.
English as a Second Language
Captions are beneficial to those learning English as a Second Language (ESL). They give students the opportunity to review confusing materials or reference difficult, complex terms that they may have had trouble translating without a written reference.
