Why adding subtitles to videos is so important

According to the BBC, four out of five viewers aged 18-25 said they use subtitles all or part of the time, Stagetext’s figures said. The charity’s research suggested an average of 31% of people would go to more live events and shows if more had captions on a screen in the venue. Among 18-25s, that figure was 45%, compared with 16% among over-56s.
According to preply’s survey of more than 1,260 Americans, it was concluded that:
  • 50% of Americans watch content with subtitles most of the time.
  • 55% say it is harder to hear dialogue in shows and movies than it used to be.
  • 62% of Americans use subtitles more on streaming services than regular TV.
  • 57% watch content in public; 74% of Gen Z do so.

What are the benefits of adding subtitles to a video

  1. Enhanced Comprehension for Diverse Audiences

In a world where content is increasingly globalized, subtitles make films and TV shows accessible to a broader audience. They break language barriers, allowing people to enjoy content in foreign languages. For instance, shows like “Squid Game” gained international popularity partly due to subtitles making them accessible to non-Korean speaking audiences.
  1. Clarity in Dialogue

As indicated by the survey findings, many viewers struggle with muddled audio or background noise in modern productions. Subtitles ensure that the dialogue is not lost amidst these audio challenges, thus enhancing the understanding of the storyline.
  1. Assisting in Learning Languages

Subtitles can be a powerful tool for language learners. They provide a written context to the spoken dialogue, helping learners to improve their listening and comprehension skills in a new language.
  1. Adaptation to Various Viewing Environments

With the rise of mobile devices and streaming services, people are watching content in diverse environments – from noisy public places to quiet homes where they don’t want to disturb others. Subtitles allow viewers to follow along without relying solely on audio.
  1. Inclusivity for the Hearing Impaired

Subtitles are crucial for the hearing impaired, allowing them to enjoy movies and TV shows without missing out on crucial dialogue and sound cues.
  1. Multitasking and Attention Retention

In an era where multitasking is common, subtitles help viewers keep track of the plot while they might be distracted or doing something else simultaneously.
  1. Preference and Comfort

As the survey reveals, a significant number of people, especially among younger generations, prefer to have subtitles on. This preference can be due to various reasons, including better focus, understanding fast dialogue, or simple habit.
  1. Catering to Various Accents and Dialects

English, like many languages, has a wide range of accents and dialects. Shows with heavy accents, such as “Peaky Blinders” or “Game of Thrones,” are easier to follow with subtitles, ensuring that no vital plot point is missed due to misunderstandings.
Subtitles, therefore, are more than just a tool for the hearing impaired; they have evolved to enhance the viewing experience for a wider audience, adapting to the changing ways we consume content in a global, digital age.
