Video captions and subtitles are the on-screen text of what a video says, timed to the speech, and business videos need them because many viewers scroll with the sound off or cannot hear it. Captions keep your offer, prices and contact details readable, make the video usable for people with hearing loss and take a few minutes per video.

This article is part of our complete guide: Video Marketing for Business.

What is the difference between captions and subtitles?

Captions show the words and important sounds of a video in its own language, while subtitles usually translate the speech for viewers who speak another language. In everyday use the two words overlap, and in some countries subtitles covers both.

The W3C Web Accessibility Initiative notes that the two terms are used for the same thing in different parts of the world, and it separates them by purpose. Captions are an accessibility feature: a text version of the speech and the non-speech audio someone needs to follow the video. Translated subtitles help a different audience, people who can hear but do not understand the language, so they are not an accessibility accommodation in themselves. For a business posting short videos to a local audience, captions in the language you speak are the job; translation comes later, if at all.

The second split that matters is open versus closed. Closed captions sit in a separate track or file that the viewer can switch on or off, and the platform shows them over the video. Open captions are burned into the picture itself, so everyone sees them and nobody can hide them. Short video feeds lean heavily on open captions because many viewers never touch the settings, but a closed captions file still has value because platforms can read it and viewers who need larger or cleaner text can use the player's own display.

There is one more source of confusion. On Instagram, TikTok and Facebook the word caption also means the text you type under a post, the description with your hashtags. That post text is useful, but it is not a caption of the speech. When this guide says captions, it means the words of the video shown in time with the voice.

Why do captions matter for a business video?

Captions matter because a business video only works if the viewer understands the offer, and many viewers meet your video without sound. Without captions, a muted viewer sees a face talking and scrolls on.

Think about where people watch short videos: on a bus, in a queue, at a desk in an open office, in bed next to someone asleep. The Ofcom research above found people turning to subtitles because of background noise and as an alternative to raising the volume so they do not disturb others, and the same habits carry over to phones. A bakery in Leeds announcing a new weekend loaf needs the name of the loaf, the days and the street to land even when the phone is on silent. Captions are what make that happen.

Captions also protect the details that cost you sales when they are misheard. Names of products, prices, phone numbers, opening hours and place names are exactly the words a viewer is most likely to miss in a quick video with music underneath. A plumber in Nairobi saying "same day callouts across Westlands and Kilimani" loses half the message if the viewer cannot hear the area names. Written on screen, those words stay in front of the viewer for the full second or two they need.

There is a fairness reason too. People who are Deaf or hard of hearing are customers and neighbours, and a video without captions shuts them out of your marketing completely. Captioning is one of the simplest accessibility steps a business can take.

Who actually relies on captions?

Captions serve people who are Deaf or hard of hearing first, and then a much wider group who watch in noise, in silence or in a second language. Both groups are large enough to matter to any business.

The World Health Organization's March 2026 fact sheet puts the number of people needing rehabilitation for hearing loss at 430 million, over 5% of the world's population, and projects more than 700 million by 2050. Not all of them will be your customers, but in any town some of the people you want to reach cannot hear your video at all. The WAI guidance adds a further group: people who process written information better than audio. That includes some people with cognitive or neurodevelopmental conditions, which the Ofcom research also describes, where subtitles help them confirm what they heard.

Then there are viewers who can hear but cannot use sound at that moment, and viewers who follow written words more easily than a fast accent. None of these people will tell you they skipped your video because it had no captions; they simply move on. That silent loss is why captions belong in the routine.

Are automatic captions good enough?

Automatic captions are a fast first draft, not a finished job. Every platform that offers them warns that they make mistakes, so check every line before you post.

YouTube's help page on automatic captioning says the captions are produced by machine learning, that quality may vary, and that they might misrepresent the spoken content because of mispronunciations, accents, dialects or background noise. Its advice is plain: always review automatic captions and edit any parts that have not been transcribed properly. The W3C guidance goes further, warning that missing a single word such as "not" can make captions say the opposite of the speaker. For a business, a wrong price or a misspelt street name is the same kind of error.

The words most likely to go wrong are the ones that matter most to you: your business name, product names, local place names, numbers and anything said quickly over music. A sensible routine is to let the app or editor create the captions, then read them once with the sound off, as a viewer would, and fix anything that looks odd. That pass takes a few minutes for a 30 second video and catches the errors that would otherwise sit under your logo for as long as the video stays up.

Automatic captions also tend to miss sound that carries meaning. If a doorbell, a sizzling pan or a customer laughing is part of the story, a short note such as [doorbell rings] tells a viewer who cannot hear it what is happening. The WCAG understanding of captions includes meaningful sound effects and who is speaking, not only dialogue.

How should captions look on a short vertical video?

Captions on a phone should be large, high in contrast, a few words at a time, and placed where the app's buttons and text will not cover them. Readability beats style every time.

TikTok's creative best practices suggest 5 to 10 words per second when you use on-screen text and ask advertisers to keep content inside the safe zone, the area not covered by the interface. In practice that means keeping captions away from the very bottom of the screen, where the post caption and account name sit, and away from the right edge, where the like, comment and share buttons are. The middle third of the screen, slightly below the face of whoever is talking, is usually the safest place to start. Check one finished video on each app before you settle on a position, because each interface is laid out differently and they change.

Short lines read faster than long ones. Break captions at natural pauses so each block is a phrase someone can take in at a glance, and avoid splitting a name or a price across two blocks. Strong contrast matters more than colour: white or yellow text with a dark outline or a dark box behind it stays readable over a busy kitchen or a bright street. Keep one font and one style across your videos so captions become part of a recognisable look rather than a distraction.

Timing is the last check. Captions should appear when the words are spoken and leave when the speaker moves on; a caption that lags by a second makes the whole video feel out of step. Most editors let you nudge each block, and the sound off read through will show you where the timing slips.

How do you add captions on each platform?

Each platform offers its own captioning tools, and they change often, so treat the steps below as a starting point and check the app's help pages. The safest approach is to make the captions once and keep a file.

YouTube gives the most control: you can upload a captions file with or without timing, paste a transcript and let it set the timings, or type captions directly, and it creates automatic captions you can then edit. Instagram's help centre describes automatic closed captions for reels, which use speech recognition to write the speech at the bottom of the video once they are switched on. TikTok's own guidance for advertisers asks for captions or text overlays and includes closed captions among its tips for making videos accessible.

A captions file in the common SRT format is a plain list of numbered lines with start and end times. Keeping one per video means you can upload the same captions wherever a file is accepted and use it as the source for burned in captions on TikTok and Reels, instead of retyping the words for each app. If you work with a video editor or a tool that hands you a captions file, ask for it every time and store it next to the video.

What else does a captioned video need before it is posted?

A captioned video still needs a cover that earns the tap and hashtags that describe it honestly. Those two pieces decide whether the right people find the video at all.

The cover image is what people see on your profile grid, in search results and in shares, and on YouTube Shorts it shapes whether someone chooses to watch at all. Hashtags work differently on each platform and are easy to overdo, and the platforms are clear that irrelevant tags can hurt rather than help. Both deserve their own guides, so two narrower questions sit under this one: what makes a good cover image for a short video, and which hashtags a business should use on short videos. Read them once your captions routine is in place, because a strong cover and honest hashtags bring viewers to a video they can then follow with the sound off.

Questions business owners ask about captions

Do captions help a video get found?

They can help, but no platform publishes how much weight it gives to the words in a captions file. What is clear is that captions make the video understandable to people watching without sound, which affects whether they keep watching. Treat any discovery benefit as a bonus, not the reason.

Should I use open captions or closed captions?

For short vertical videos on TikTok, Instagram and Facebook, burn in open captions so every viewer sees them. Keep a closed captions file as well and upload it wherever the platform accepts one, especially YouTube. Using both costs little once the words are checked.

How long does it take to caption a 30 second video?

With automatic captions as a draft, the review usually takes a few minutes: read once with the sound off and correct names, numbers and anything said over music. The time grows with fast speech, several speakers or heavy background noise. It is far quicker than fixing a wrong price after people have seen it.

Do I need captions if my video has no talking?

If the video is only music and pictures, you need on-screen text that carries the message instead. Write the offer, the price and how to reach you as short text blocks. If a sound matters to the story, describe it in brackets.

Should I translate captions into other languages?

Translate only when a real share of your customers speaks another language and you can check the translation. A wrong translation of a price or a promise does more harm than no translation. Start with accurate captions in the language you speak in the video.

Caption your next video this week

Pick the next video you plan to post and give it a full caption pass before it goes live.

Let the editor create the captions, then read them once with the sound off. Correct every name, price, place and number, and check that no line is hidden under the app's buttons. Save the captions file next to the video so you can reuse it wherever a file is accepted.
