Subtitles and captions are no longer just an accessibility feature. They have become a powerful tool for content creators. From improving viewer retention and engagement for those watching on mute, to making videos accessible to a wider audience, adding captions can significantly enhance the performance of your content.

In this guide we cover all things ‘caption’ helping you ensure every word of your video reaches your audience.

Captions and Subtitles; What’s the difference?

The terms caption and subtitle are often used interchangeably, but they do both serve slightly different purposes. Subtitles are typically used to translate spoken dialogue into another language, as in the familiar term ‘subtitled film’. Captions on the other hand are designed to provide a text version of all important audio within a video. This can include speech, sound effects, and music cues.

Captions are of particular value to viewers who are deaf or hard of hearing, watching on mute or viewing content in a noisy environment. Subtitles help creators reach international audiences. Understanding the difference between the two terms can help you choose the right option for your video.

Why captions matter

Captions have become an essential part of modern content creation. Whatever platform you are producing video for, captions help viewers follow along with the narrative regardless of where they are watching.

For example, many users browse social media in public spaces where it would be inappropriate to play audio out loud. Captions allow them to consume content without the need for headphones.

Another advantage of captions is to help improve comprehension. Being able to read along with the dialogue in a video can help viewers to retain more information as well as stay engaged throughout the video. How many of you find yourself reading along to captions subconsciously even though the audio is playing?

Accessibility benefits

Another important reason to add captions is accessibility. Captions make video content available to people who are deaf, hard of hearing, or have auditory processing difficulties.

This naturally helps you reach a wider audience as well as demonstrating that you value inclusivity. Including accurate captions ensures that everyone can enjoy and understand your content, regardless of their hearing ability.

SEO benefits and discoverability

Many creators overlook the fact that captions can also help improve your chances of your video being discovered on platforms. This is because search engines can’t watch video content, but they can read text. When you add captions in the form of a transcript, you’re providing valuable information that search engines can index.

For platforms such as YouTube, captions may help improve keyword relevance and provide additional context about your content. This can increase the likelihood of your videos appearing in search results and being discovered by new audiences.

Adding hard-embedded (burned-in) captions alone will not help with discoverability. In order to benefit from the added SEO boost you should upload a caption file (such as .srt). YouTube does generate it’s own auto-generated captions but these can be inaccurate so it is important that you take the time to correct any mistakes. This will give YouTube a clean text transcript that can help it understand:

And, while captions alone won’t guarantee higher rankings, they are an effective additional tool to support a broader video SEO strategy.

Open captions and closed captions (CC) What’s the difference?

Now that we understand the difference between captions and subtitles what is the difference between open and closed (CC) captions. Closed captions allow the user to close or disable the captions at will. (CC) captions are therefore generated by the video platform.

Open captions on the other hand are embedded directly into the video itself. This means they are always visible and cannot be turned off by the viewer. Because they form part of the video image, they are often referred to as burned-in or hardcoded captions.

This table explains the core differences:

Closed captions vs Open captions

Closed Captions	Open Captions (Burned-In)
Can be turned on or off	Always visible
Stored as a separate file or track	Permanently embedded in the video
Often used for accessibility	Often used for style and engagement
Viewers can customise appearance on some platforms	Creator controls the appearance
Can support multiple languages	Fixed to whatever is shown in the video

Open captions vs closed captions: Which should you use?

Once you’ve decided to add captions to your videos, the dilemma every creator faces is whether to embed the captions directly into the video or use a platform’s automatic captioning tools.

The main advantage of using burnt in (open) captions is they give creators complete control over the look and deployment of the text. This includes styling, placement, colours, animations, and timing. This functionality makes open captions particularly popular in short-form content on TikTok, Instagram Reels, and YouTube Shorts.

Closed Auto generated captions, on the other hand, offer distinct advantages of their own. The first being the viewers ability to turned them on or off. There is also the SEO advantage that we have already covered. Platforms such as YouTube, Facebook, TikTok, and LinkedIn all offer automatic captioning features making the process simple. YouTube even allows creators to upload their own caption files for improved accuracy.

To help you decide which approach is right for your content, here’s a quick breakdown of the advantages and disadvantages of both captioning methods.

Open Captions (Burned-In Captions)

Advantages

• Always visible, so viewers don’t need to enable captions.
• Ideal for social media platforms where videos often autoplay without sound.
• Complete control over font, colours, animations, positioning, and timing.
• Can become part of your visual branding and editing style.
• Ensures every viewer sees the same caption experience.

Disadvantages

• Cannot be turned off by viewers.
• May clash with platform-generated captions if both appear at the same time.
• Difficult to correct once the video has been exported and published.
• Don’t offer viewers accessibility customisation options such as changing font size or colour.
• Can obscure important visual elements if not positioned carefully.

Closed Captions (CC)

Advantages

• Viewers can turn captions on or off as needed.
• Better for accessibility, allowing users to customise how captions appear on some platforms.
• Easy to edit and update without re-exporting the entire video.
• Support multiple languages through additional subtitle tracks.
• Can provide platforms such as YouTube with an accurate transcript of your video.

Disadvantages

• Some viewers may never enable them.
• Platform-generated captions can contain errors if not reviewed.
• Less creative control over styling and presentation.
• Appearance may vary between platforms and devices.
• Not always available or supported equally across every platform.

What do most creators choose?

There isn’t a single right answer as to which type of caption to use. Instead there are trends that cover certain types of content. Open captions are often the preferred choice for short-form content, so sites like TikTok, Instagram Reels, and YouTube Shorts. This is because viewers of short form content are more likely to be watching on a device with no volume so it guarantee’s they can follow the video. Closed captions are generally favoured for longer-form content, particularly on YouTube, where accessibility and viewer choice are important.

Many creators now use a combination of both approaches: stylish burned-in captions to improve engagement and readability, alongside platform captions to support accessibility and give viewers greater control over their viewing experience.

How to add captions

The process of adding captions will vary depending on whether you choose open captions (burned-in captions) or closed captions. Fortunately, most modern editing software and social media platforms make both options relatively straightforward.

Adding open captions (Burned-in captions)

You will need to add these captions during the editing process, generally as one of the last steps. Many video editing tools, including CapCut, Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro, offer automatic caption generation. These facilities use AI to analyses the audio and speech to create a script. The captions can then be customised with different fonts, colours, animations, and positioning. You should also proof read any auto generated text as even the best tools can make mistakes.

Adding closed captions (CC)

Applying closed captions is a simpler process. Platforms such as YouTube can automatically generate captions from your video’s audio, so you can simply switch on the closed captions option when uploading you content. It is always strongly recommended to review the captions for accuracy as it’s not always 100% reliable.

Creators can also choose to upload caption files, such as SRT files. These can provide more accurate timing and transcription. This is often the preferred option when publishing longer-form content, educational videos, and professional productions where it is important to support reliable accessibility.

Making captions pop! Getting creative with text

In recent years captions have evolved to become more than just an accessibility tool. They’ve become a design feature in their own right. Across TikTok, Instagram Reels, YouTube Shorts, and other short-form platforms, creators are getting inventive with the way captions are displayed. They are using animated captions and bold decorative fonts to grab attention and add personality to their content.

For example, modern caption styles often highlight individual words as they’re spoken or use different colours to draw attention to key phrases. These techniques are great for grabbing viewers attention, especially during the crucial first few seconds of a video.

While eye catching captions can be effective it should not be at the expense of readability. Captions should remain easy to read on all devices. They should also complement your content rather than distract from it. The most effective caption designs strike a balance between creativity and accessibility.

Common mistakes to avoid

While adding captions is hugely beneficial, poor captioning can have a negative affect on the viewer experience.

Be aware of the following potential pit falls:

• Don’t rely entirely on auto-generated captions without proofreading them.
• Applying text that is too small to read on mobile devices
• Displaying captions for too short a time
• Placing captions over important visual elements
• Positioning your open captions too low so that when they are viewed on slightly different social media ratio’s they get cut off
• Having text that cannot be read easily due to clashes with the background. i.e Black text on dark backgrounds

Taking a few extra minutes to review your captions before publishing or pushing your video live can make a significant difference to the overall quality of your content.

Using subtitles for international audiences

As we learnt earlier subtitles fulfil the role of translator. They are therefore a powerful tool in reaching a worldwide audience. To successfully enable subtitle capabilities it is best not to use burned-in captions. Instead, if you intend your content to be viewed in other languages use closed captions.

One advantage of closed caption subtitles is that platforms like YouTube can automatically translate them into other languages. Viewers will have to select “Auto-translate” in order for the video to display the subtitles in their native tongue. In some cases, YouTube may translated the captions based on the user’s language settings, but it generally isn’t as seamless as platforms like Netflix.

Captions, music, and sound effects

Captions help viewers understand what’s happening on screen when it’s not possible to hear the audio. As well as dialogue, good captions will also describe other forms of audio such as music cue’s, sound effects and atmospheres. Think important audio cues, such as “[upbeat music]”, “[crowd cheering]”, or “[door slams]”. These cues provide context while highlighting the role that sound plays in the viewing experience.

While the captioned descriptions can help set up the scenes they don’t replace the impact of great audio. Music and sound effects remain essential elements that help shape emotion, build atmosphere, and enhance engagement.

The key to a fully rounded video is to combine accurate captions with high-quality production music and professional sound effects. This helps create more immersive, engaging content that resonates with audiences, whatever their circumstances.

Summary

Captions and subtitles are no longer an optional choice for creators. They have become an established and essential aspect of modern content creation. With the changes in ways people consume online video content it’s vital you provide a written as well as visual framework. And like so many aspects of video production, where competition for attention and retention is high, captions have also started to be used as an effective stylistic engagement tool.

For most creators, the question is no longer whether to incorporate captions, but how to deliver them most effectively. The answer will depend on the type of content you produce, the platforms you publish on, and the audience you’re trying to reach. As with many aspects of video production, your captioning strategy will likely evolve over time as you experiment with different approaches and discover what works best for your viewers.

Hopefully, this guide has provided the information you need to make informed decisions about captioning and subtitles. Whether you opt for open captions, closed captions, or a combination of both, a thoughtful approach to captioning can help create a more accessible, engaging, and complete viewing experience that keeps audiences watching from start to finish.
