What are subtitles?
Subtitles are short blocks of text that transcribe the spoken language in a video, allowing you to read what is being said while watching the video. They usually follow the speed of speech and the rhythm of the editing, so the text appears for two to seven seconds at a time. Subtitles are usually found at the bottom of the screen, and they can either reproduce the dialogue in the same language or provide a translation from another language. In other words, subtitles make video content more accessible and understandable across languages and audiences.
Although subtitles are traditionally associated with movies and TV, they have also taken on a significant role in digital communication. When you produce videos for social media or advertising, subtitles are crucial because many people watch videos with the sound off. This way, subtitles can ensure that your message still gets across—even when the user is on the train or scrolling through their phone with the sound off.
How do you use subtitles?
You use captions to make video content more accessible and engaging. In their simplest form, they simply follow the dialogue, but you can also include descriptions of sounds and music for viewers with hearing loss. You can create them manually by typing the text and adjusting the timing, or you can use automated tools that generate captions using speech recognition. It’s important that the text appears on screen long enough to be read at a natural pace—typically three to six seconds, depending on the length.
If you work in video marketing, you can incorporate subtitles as part of your overall content production. For example, when you’re editing a video for social media, you can embed subtitles directly in the editing software or add them as separate files in formats such as SRT or VTT. This makes it easier to repurpose the video across different platforms, each of which has its own preferences for format and display.
That's why you should use subtitles
Subtitles aren’t just a matter of accessibility—they influence how your content is understood and remembered. Many people watch videos without sound because they’re in situations where sound isn’t practical. If your video communicates only visually, you lose a large part of your message. With subtitles, you preserve the context and increase the likelihood that the viewer will watch the video all the way through.
At the same time, subtitles help anchor your message linguistically. When users both see and read the same message, it enhances their understanding and retention of key points. This mechanism is particularly relevant when working with branding or campaigns where recognition of tone, name, and product is crucial. Even short commercials with subtitles can create more impactful communication in this way, because you’re actively combining sound, visuals, and text.
What types and varieties are available?
There are essentially two types of subtitles: translated and transcribed. Translated subtitles convey the meaning from one language to another, such as from English to Danish. Transcribed subtitles reproduce what is said in the original language and often include additional information for viewers with hearing loss—such as descriptions of music or background sounds.
As a video producer or content manager, you can combine the two formats so that your video reaches both international users and people with hearing impairments. When publishing content on social media, you might even consider adding multiple language versions if your target audience spans several markets. Of course, this requires you to keep track of translations and file formats, but the investment pays off in the form of greater reach and a better user experience.
How do you use subtitles in practice?
The most practical approach is to create your subtitles as text files that are synchronized with the video. Popular formats such as SRT and VTT are widely used on social media and video platforms like YouTube or Vimeo. You can create your files in a simple text editor, where each text block is assigned a timestamp, or you can use dedicated platforms that offer automatic generation and editing.
When you take a strategic approach to content marketing, you can link the subtitling process to SEO and performance analytics. For example, you can incorporate keywords into your YouTube subtitles so the platform can more easily understand the context of your video. The same applies to paid social media, where clear subtitles can increase the click-through rate in the news feed and ensure a better ROAS, because more people will get the message.
An example of how you can use subtitles in your marketing:
What should you keep in mind?
Although automated tools provide quick results, high-quality subtitles still require human editing. You need to ensure that the text is grammatically correct and that it matches spoken expressions and intonation. Small adjustments—such as pauses, stress, and word choice—make a big difference in how the video is perceived. You should also check the readability: choose a clear font, avoid characters that are too small, and ensure there is contrast with the background.
Finally, you should consider the implications for language learning if you produce content in multiple languages. Viewers learn best when subtitles match the spoken language, and poor timing or translations can actually hinder comprehension. Therefore, you should test your subtitles on a representative sample of users before rolling out the video to a wide audience.
In other words, when you work professionally with video and digital marketing, subtitles become an integral part of the overall picture. They support both your messaging and your strategy for SEO, social media, and brand identity—and they make it easier to reach your entire audience, no matter where or how they view your content.
