All Things Captions

Captions are time-synchronized text that can be read while watching a video and are usually noted with a CC icon. They originated as an FCC mandate in the 1980s, but have since expanded to online video and internet applications.

Captions assume the viewer can’t hear, so they include relevant sound effects, speaker identifications, and other non-speech elements to make it easier for the viewer to understand.

Many people use captions, subtitles, and transcripts interchangeably, but it’s important to distinguish between them because they all mean something different.

As mentioned, captions are time-synchronized and assume the viewer can’t hear. Subtitles, on the other hand, assume the viewer can hear, but can’t understand the language. Transcripts are just a plain text version of the audio and aren’t time-synchronized.

Creating Captions

If you want to DIY your captions, you can utilize a free automatic caption tool with YouTube. Although accuracy is a huge issue when it comes to automatic captions, the video platform allows users to go back and edit the script if necessary.

Whether you create captions yourself or go to a professional captioning company, it’s important to consider quality standards. The industry standard is a 99% accuracy rate. It’s based on word f-for-word, meaning each word has that percentage chance of being wrong.

Captioning Accuracy Rates
Word-to-Word Accuracy 1 of x Words Incorrect 8-Word Sentence Accuracy 10-Word Sentence Accuracy
50% 1 of 2 0% 0%
67% 1 of 3 4% 2%
75% 1 of 4 10% 6%
85% 1 of 7 27% 20%
90% 1 of 10 43% 35%
95% 1 of 20 66% 60%
98% 1 of 50 85% 82%
99% 1 of 100 92% 90%

Publishing Captions

There are many ways to publish captions. The most common way is through a sidecar file, which is a file that stores captions so they can be associated with the corresponding video.

Another way is to encode captions onto the video. These are found in many kiosks and offline videos and can also be turned off or on.

Open captions are burned into the video and can’t be turned off or on. Open captions are great for social videos since most social media platforms don’t support captions.

Lastly, integrations are simply a publishing process for captions. It’s a preset workflow between your captioning process and video publishing process. It helps make the captioning process more streamlined.
