Learn the difference between closed captions vs subtitles so you can better understand which is best suited for your video project..

Whether they’re scrolling for entertainment or searching for how-tos on YouTube, 50% of people report watching videos with captions or subtitles. While both perform similar roles and can improve viewer engagement, video captions and subtitles have specific use cases. In this article, we’ll explore the difference between closed captions vs subtitles so you can better understand which is best suited for your video project.

Is there a difference between captions vs subtitles?

Yes—captions and subtitles have different purposes and serve distinct audiences. For example, captions are usually more descriptive than subtitles and include sound effects, speaker identification, and other auditory information. On the other hand, subtitles are a textual representation of the dialogue in a video.

What are captions and when should you use them?

Captions are descriptions of the video audio features. They may include dialogue, music, and sound effects. Video captions typically appear at the bottom of the video as white text on a dark background. Captions make video content more accessible and easier to understand.

Open captions

Have you ever seen a movie where the characters suddenly start speaking a different language? Then you’ve likely seen open captions appear on the screen.

Open captions refer to captions that are part of the video track and are visible to all viewers. They are part of the video itself, so viewers do not need to figure out how to turn them on.

Open captions are often used for informational videos that are to be widely distributed to a diverse audience. A workplace training video, for example, may use open captions to maximize accessibility.

Closed captions

Closed captioning is the most common type and can be toggled on and off at will by the user. On social media and video-sharing platforms such as YouTube, a button is typically embedded in the media player labeled “CC.” When the viewer wants to see the captions, they can do so by clicking the CC button.

Closed captions are often auto-generated, meaning the video-sharing platform uses AI to create captions. While auto-generated captions are helpful in a pinch, they are often inaccurate and typically lack readability features such as punctuation.

To ensure viewers get the maximum benefit from video captions, many creators hire a professional transcriptionist to create closed captioning.

Why do viewers prefer to use captions?

Here are a few reasons viewers may choose to enable captions:

  • Deaf or hard-of-hearing viewers use captions to follow along without missing any vital details.
  • Many viewers choose to enable subtitles simply because they like being able to read along.
  • Captions are helpful in situations when a viewer may want to avoid turning up the volume on their device, such as in a shared space.
  • Language learners may choose to enable video captions to aid their understanding of dialogue, especially when spoken quickly or heavily accented.

Why invest in closed captioning?

Make your video more accessible.

With quality captions, your video will be accessible to deaf and hard-of-hearing viewers. Making provisions for your deaf and hard-of-hearing viewers is more than a kind gesture—it significantly improves their quality of life.

Broaden your video’s reach

Captioning is a simple accessibility feature that helps viewers from all walks of life engage with your content. By including video captions, you’re sure to attract more viewers.

Help educate viewers

Captions are commonly used by those who are using videos to learn languages. Generally speaking, it’s easier to understand written language than spoken. Therefore, providing captions is extraordinarily helpful for language learners.

Boost your SEO

Well-captioned videos are great for SEO. Search engines can’t “watch” a video, but they can detect text in your captions. So including a few keywords in your captions can help audiences find your videos more easily.

Create a better user experience

Captions help viewers engage with your video, no matter who they are or where they are. With captions, viewers can easily watch without headphones or follow along despite a language barrier. (Considering there are more than 500 million Spanish speakers in the world, Spanish transcription sounds like a good idea!)

Tips for successful captioning

When learning how to caption your videos, there are a few things to consider. So here are a few tips for successful captioning:

Don’t rely on auto-generated captions.

It may seem easier to let your video-sharing platform do the captioning, but auto-generated captions aren’t very accurate, and caption mistakes make things more difficult for viewers. Edit your captions to ensure they’re accurate and readable.

Do include the following:

  • All dialogue and narration, including speech effects such as stuttering
  • Song identification with artist name and lyrics
  • Identification of off-screen speakers
  • Audio descriptions of sound effects relevant to the story (e.g., explosions)

Don’t include the following:

  • Every single word or sound effect if it’s impractical to do so (e.g., in areas of fast-paced dialogue, you may leave out repeated words.)
  • Text that’s already on-screen (e.g., signage at a protest)

Maximize readability.

To ensure your text can be easily read by audiences, make sure you follow grammar and spelling conventions. Take timing into consideration as well—captions should stay on-screen for at least two seconds. In addition, lines shouldn’t exceed 37 characters, and captions should not be longer than two lines.

Ensure the captions match the video.

Captions should reflect what’s happening on screen as much as possible. That may mean including ellipses to account for pauses in speech, adjusting the timing of the caption to coincide with the video, and including descriptions of sound effects.

What are subtitles and when should you use them?

While captions are meant to assist those who can’t hear the audio, subtitles are intended to help bridge a language gap between the viewer and the video using on-screen text. Subtitles are captions translated into a different language.

For example, if you’re a native English speaker who would like to enjoy a Spanish film in its original language—that is, a non-dubbed version—you may choose to watch it with English subtitles. That means you’ll hear the original actors’ voices and intonations while still understanding what’s happening.

Open subtitles (hard subtitles)

Hard subtitles, or open subtitles, are added to the video itself and appear in-frame. That means the viewer doesn’t need to do anything to turn them on.

However, because it’s “burned” into the video, open subtitles only allow for translation into one language. This may be suitable in certain situations; for example, a Polish video being distributed to the English market.

Closed subtitles (pre-rendered)

Similar to closed captions, closed subtitles can be turned on and off by the viewer. On a technical level, they’re encoded as a separate video file that’s laid over the original.

With closed subtitles, it’s possible to add multiple language options to a single video. Videos made for a diverse international audience typically contain closed subtitles in several of the world’s widely-spoken languages—and with enough translators, there is no end to the number of translations you could provide using closed subtitles.

Soft subtitles

Soft subtitles are similar to closed subtitles. But rather than existing as a video overlay, soft subtitles live in a separate file that runs alongside the video. “Fansubs,” or fan-created subtitles, are typically soft subtitles.

Is subtitling a worthwhile investment?

If your video is intended for an international audience, subtitling is a no-brainer—subtitling may be the difference between thousands or millions of views. That said, subtitling can get pricey. So here are a few things worth considering:

Does your video have global appeal?

When deciding whether it’s worth investing in subtitles, ask yourself whether your videos have global appeal. For example, if you create video essays about life in American cities, it might not make sense to subtitle your videos. But if your video is about a famous telenovela, subtitles are a good move.

Do you live in an area with many speakers of other languages?

Another variable to consider is whether you want to appeal to speakers of other languages. If so, hiring translators to help you with subtitles may be a good idea.

For example, a channel that caters to the Los Angeles market may subtitle their shows in Spanish, Chinese, Tagalog, and Vietnamese to help make video content accessible to a broader audience.
